System for retrieving and processing stability data from within a secure environment

[0001] The present invention generally relates to a method which will systematically check for and retrieve data from a known, public system to a system inside company firewall restraints. This data is processed and stored into an internal database for the express purpose of allowing timely access to stability and configuration information, for field engineers or managers within a proprietary company database. The method is able to function virtually unattended once initial set up is complete.

[0002] This application is related to co-pending U.S. Ser. No. 10/308,388, entitled “Method For Scanning Windows Event Logs In A Cellular Multi-Processing CMP Server”, which is incorporated herein by reference.

[0003] This application is related to co-pending U.S. Ser. No. 10/308,370, entitled “Method For Collecting And Transporting Stability Data”, which is incorporated herein by reference.

[0004] Previous methods for transporting customer configuration and stability information were prone to breaches of system security, cumbersome and either too costly in terms of processor utilization or not current. A means was necessary to provide a mechanism whereas data could be swiftly retrieved from a known public location into an internal, secure system-operating environment in a regular and timely manner, without using excessive amounts of the processor.

[0005] The general purpose of the software methodology described herein is to systematically check for and retrieve data from a known, public system to a system inside company firewall restraints. This data is processed and stored into an internal database for the express purpose of allowing timely access to stability and configuration information, for field engineers or managers within the company. The method is able to function virtually unattended once initial set up is complete. This methodology is part of a system designated as the Availability Monitor System.

[0006] One prior art method to which the method of the present invention generally relates is described in U.S. Pat. No. 6,128,647 entitled “Self Configuring Peer To Peer Inter Process Messaging System”. This prior art method provides remote program execution, data transport, message communication, status communication and relocation of computer resources by using an arbiter associated with each computer. An originating arbiter of a process resource sends messages between arbiters that are received by each arbiter and then sent to a destination arbiter, if required. If necessary, the message may be retransmitted by intermediate arbiters and eventually received by the destination arbiter, which interprets, and executes the message. As a result, the arbiters provide actual communication between the resources. Each arbiter may be resident in each of a plurality of computers, which are part of a network linked by a network. Each arbiter independently reviews and processes the messages so that the computers communicate directly with each other on a peer to peer basis without the need for a master controlling program or other gateway for controlling and processing the messages as the messages are transmitted between computers.

[0007] The present invention differs from the above prior cited art in that the prior invention focuses on self-configuring or remote program execution. The method of the present invention retrieves files from a public location and processes them within a secure environment, which is not related to the method of the prior art.

[0008] Yet another prior art method to which the method of the present invention generally relates is described in U.S. Pat. No. 6,301,584 entitled “System And Method For Retrieving Entities And Integrating Data.” This prior art method is a data integration system and method which gathers information dynamically from one or more data sources, which may be located at different servers and have incompatible formats, then structures the information into a configurable, object-oriented information model, and outputs the information for the user according to an associated, configurable visual representation with automatic content classification.

[0009] The present invention differs from this prior art in that the cited prior art deals with integrating data. This is in no way related to the method of the present invention, which is to retrieves files collected in known public locations for processing at a secure central site. The data in these files is then used to update a central database.

[0010] Yet another prior art method to which the method of the present invention generally relates is described in U.S. Pat. No. 6,141,699 entitled “Interactive Display System For Sequential Retrieval And Display Of A Plurality Of Interrelated Data Sets”. This prior art method is a method, system and program product for monitoring, from a client computer system, the performance of an application program residing on a server computer system. A probe program residing at the client computer generates requests for the services of the application program and records transaction records based upon service responses from there. The requests and transaction record generation is controlled by a set of probe configuration information units at the client computer. Transaction records are provided to a central repository whereat statistical information is pre-processed and inserted into statistics tables. A display system enables a computer user to interactively request and view a plurality of displays of data sets of the monitoring data. Each data set includes data elements, which may be interactively indicated by the viewer to cause the retrieval and display of related data sets having data elements associated with those in the original display.

[0011] The present invention differs from this prior art in that this referenced prior art deals with interactive displays. This prior art method does not teach the method of the present invention of updating a central database with data contained in files sent from a myriad of sites through a firewall.

[0012] Yet another prior art method to which the method of the present invention generally relates is described in U.S. Pat. No. 6,026,392 entitled “Data Retrieval Method And Apparatus With Multiple Source Capability”. This prior art method involves a generation of output or reports on information contained in a data source which may be any of two or more types of source data, in a standardized or uniform manner. A plurality of drivers are provided specific to different types of source data which include programming for identifying structural or other characteristics of the various data sources, e.g. for use in defining a new database. Preferably the new database is configured to permit highly flexible and/or rapid output or reporting or is otherwise optimized for reporting purposes. In one embodiment, this prior invention includes conversion of one or more data sources into one or more uniform databases, preferably generating one or more key categories for organizing the data, optionally generating category groupings or rollups and additional data or optional references. In one embodiment, one or more databases are created which have a degree of uniformity of structure, even though they may be based on two or more different data sources, which may have very different structures. The different data sources are automatically analyzed and this analysis can be used to identify and/or create categories of data for use in organizing the data.

[0013] The present invention differs from this prior art in that the referenced prior art teaches the actual structure of the database, whereas the method of the present invention teaches how specialized files can be organized in a database for ease of evaluation of partitions and service processors. This prior art is unrelated to the present inventions method of using a database to store data that has been retrieved from customer sites.

[0014] Yet another prior art method to which the method of the present invention generally relates is described in U.S. Pat. No. 4,815,030 entitled “Multitask Subscription Data Retrieval System”. This prior art method is a multitask multi-user system which provides for efficient transfer of data from a remote data base to individual subscribers and has particular utility in the distribution of stock market data. A primary provider distributes the incoming data directly to user tasks or to an inquiry provider or a monitor provider. The inquiry provider responds to specific inquiries by users for information in the database. The monitor provider maintains lists of information, which are being monitored by the host computer for individual users. The inquiry provider and the monitor provider do not repeat requests to the remote database where a similar request is already pending from another user. Data transfer paths between tasks are established by a code module, which may be linked to any of the tasks. The transfer paths are established using information from a configuration list and they are monitored by the operating system through a wait list established for each user task. Providers in the system may establish subscriber lists through the code module.

[0015] The present invention differs from this prior art in that the method of the present invention does not relate to multi-tasking or a multi-user system, as does the cited prior art. The prior art method is unrelated to the present method, which is intended for one central secure engineering site to retrieve files from multiple customer sites for subsequent evaluation.

[0016] It is therefore an object of the present invention to systematically check for and retrieve data from a known, public system to a system inside company firewall restraints.

[0017] Still another object of the present invention is to access specialized data files, then process and store data in an internal database.

[0018] Still another object of the present invention is to allow timely access to acquired stability data and configuration information.

[0019] Still another object of the present invention is to function to hold stability information data and to provide this function virtually unattended in a timely manner.

[0020] Still another object of the present invention is to provide a secure method for accumulating customer data for subsequent evaluation.

[0021] The present method provides a means for retrieving stability data from a non-secure site to a secure site. This data is then deposited into a central repository for the purpose of providing a central Unisys engineering group with a means to measure system stability and availability. This method provides a piece of an Availability Monitor system that will ultimately be used to detect potential hardware and software problems in an attempt to support the customer thereby adding integrity to the system.

[0022] Still other objects, features and advantages of the present invention will become readily apparent to those skilled in the art from the following detailed description, wherein is shown and described only the preferred embodiment of the invention, simply by way of illustration of the best mode contemplated of carrying out the invention. As will be realized, the invention is capable of other and different embodiments, and its several details are capable of modifications in various obvious respects, all without departing from the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive and what is intended to be protected by Letters Patent is set forth in the appended claims.

  General Overview:

[0182] FIG. 12 is a diagram illustrating the components, which utilize the Availability Monitor program 20. The Availability Monitor Program (20) is installed on a customer's ES7000 service processor (10). The Availability Monitor program (20) scans the Service Processor System Event Log (130) and Application Event Log (140) searching for information relative to the system's stability. This stability information is interpreted and stored in a local stability database (110) that also resides on the customer's ES7000 Service Processor (10) and is periodically written to an XML file. This XML File (120) is then transported to a public server and fetched from across the firewall to a private secure server by the Availability Monitor Transport program (40) and subsequently stored in a central Unisys database (80). From this location, Unisys executives and engineers can extricate reports on the information therein to proactively view each customer's system availability.

[0183] This method focuses specifically on gathering the XML files from one of 2 public non-secure servers to a secure private server and then processing the data to store into a central Unisys database (80).

[0184] FIG. 13 is a diagram illustrating the components used when transferring data to the Unisys environment from a number of Availability Monitor Programs operating in the NUL (items 1311, 1312, 1313) and Public (items 1302, 1303, 1304) environments. Within the NUL environment (item 1310) Availability Monitor Programs send data to a NUL server which collects and stores this data for subsequent retrieval by the CMPTRANSPORT in the NUL environment. The NUL CMPTRANSPORT program retrieves this data from the NUL server (item 1316) and updates a NUL Central Database (item 1315) and at the same time sends this data to the Express server (item 1307) via a proxy server (item 1314). The purpose of the proxy sever (item 1314) is to act as a gateway though the NUL firewall 1Cn to the express server (item 1307).

[0185] Within the Unisys environment CMPTRANSPORT (item 1301U) pulls data from the public server (item 1305) and express server (item 1307) and updates the central Unisys database (item 1307). The NUL environment cannot directly communicate with the Unisys environment, and therefore must pass data through the public environment first. The proxy server 1314 is what makes the connection from the NUL environment to the Unisys controlled environment possible.

[0186] Previous methods for transporting proprietary information of any type from customers to a central site maintained by another company for support and similar purposes were prone to breaches of system security, were cumbersome, or were too costly in the utilization of processor resources. A means was necessary for multiple customers to be able to send data to one site without any possibility that anyone else—including other customers who are also sending data to that site—could accidentally or deliberately access that information. Moreover, a means was necessary to provide a mechanism whereby data could be swiftly retrieved from a known public location into an internal, secure system-operating environment in a regular and timely manner without using excessive system resources. To protect the customers as well as the company providing the service, it was crucial to restrict access both to the known public location and to the internal location.

[0187] The current method is able to systematically check for and retrieve data from a known, public system to a system inside company firewalls. This data is processed and stored into an internal database for the express purpose of allowing timely access to stability and configuration information for support personnel or managers within the company. The method is capable of functioning virtually unattended once initial setup is complete.

[0188] The current method prevents access to the files that other customers have transmitted by providing all users with user codes that permit only write access. This prevents external users from accessing or even listing the contents of the common folder into which all files are sent for processing.

[0189] The program CMPTransport is automatically initiated when new files appear in the input folder. CMPTransport copies files from the input folder and updates the central database with their contents. After files have been read, they are moved to an archive folder if they were successfully processed, or they are moved to an errors folder for later analysis if there are problems with the files.

[0190] This method further describes the gathering of stability data from both an NUL proprietary environment and a Unisys proprietary environment. Both environments perform the function of collecting stability and configuration data from systems and partitions and packaging it within an XML file.

[0191] In the NUL environment, this information in the XML file is first transported by NUL customers' Availability Monitor programs to an NUL public server. The CMPTransport within this proprietary NUL environment imports the XML files and then exports these files across an NUL firewall via a proxy server to a public Express Server that is readily accessible by the Unisys proprietary CMPTransport.

[0192] Within the Unisys environment, the XML file information is transported to a public Unisys Server. The CMPTransport in this environment imports XML files from both the Unisys public server and the Express server. CMPTransport then processes the information by reading the XML files and storing them into a central database on a private secure Unisys server for subsequent executive reports.

[0193] Referring now to the drawings, and FIG. 1 in particular. CMPTransport 1D is a program that runs in a secure environment within a proprietary firewall 1C. It imports files from across this firewall from servers where they are collected as referenced by file items 1A and 1B, respectively shown as Client XML files and NUL XML files. These files are placed in a temporary input folder referenced by item 1F for subsequent processing by the PROCESSFILES function, 1E, which is the procedure within CMPTransport, item 1D. The program 1D is initiated through a command “Update Database Now” 1G, at which time all the files are pulled in from the input folder 1F, and then output to a central proprietary database (item 1H), which is accessible only to the people within the proprietary environment. There are two versions of the CMPTransport, 1D, one that runs within the proprietary environment, and the second, which runs on the NUL environment. When run in the NUL environment, the files are output to the NUL XML file folder, 1B, which are then accessible by the proprietary environment.

[0194] Referring now to FIG. 2, which is a diagram that illustrates the data flow of the PROCESSFILES function, 1E. PROCESSFILES, 1E, is the main procedure within CMPTransport 1D that handles the importing of client XML files (item 1A), and subsequently writes them to the central proprietary Database (item 1H). Procedure IMPORTXMLFILES (item 2F) reads all the files across the firewall 1C from the storage unit where the client XML files 1A are stored, and outputs them to an input folder (item 1F) for subsequent processing. If the system is running in the proprietary environment, the procedure IMPORTNUL_XMLFILES is executed (item 2G), which reads in the NUL XML files (item 1B) and outputs those files into the input folder (item 1F). When running in the NUL environment, all the files accumulated in the input folder (item 1F) are read in by the EXPORTXMLFILES procedure (item 2H), and output to the NUL XML server files (item 1B) for subsequent import by the proprietary environment. After all the files are accumulated in the input folder (item 1F), the OPENXMLANDFINDVERSION (item 2I) opens each individual XML file, and verifies if it's a valid XML file, and allows continuation by READXMLFILE (item 2J). READXMLFILE reads each individual XML file from the input folder (item 1F) and processes it and stores it in the central proprietary database (item 1H).

[0195] FIGS. 3A, 3B, 3C, and 3D illustrate the procedure for PROCESSFILES, which describes how XML files are accessed and processed.

[0196] Now referring to FIG. 3A, which begins when PROCESSFILES (item 1E) is initiated by the command “Update Database Now” in item 3A. Next there is a check made as to whether or not there are input folders for both the archive and the defined input folder (item 3B). If the answer to 3B is no, processing cannot be taken any further, and the processing returns to the caller. If the folders are defined, item 3C asks if the Server Box option (item 11A) is checked. The Server Box option (item 11A) will indicate whether files are to be imported across the firewall from an external server. If the answer to 3C is no, the program proceeds to FIG. 3B. If the answer to 3C is yes the user code and password are obtained from the system registry (item 3D). Next, the program will call IMPORTXMLFILES (item 2F) passing the parameters input directory, the server IP address, the user code, and the password. The procedure IMPORTXMLFILES is used to copy files across the firewall from the various servers. The sequence after step 2F continues to FIG. 3B.

[0197] Now referring to FIG. 3B, which begins with an inquiry to check whether or not the program we are running was compiled for execution on an NUL system (item 3F). If the answer to inquiry 3F is yes, a process to get proxy server password from registry is initiated (item 3H). This is a password that NUL uses because they use a proxy server (FIG. 13) for transmitting data to Unisys central engineering. Next, when calling EXPORTXMLFILES (item 3J), the parameters input directory, NUL IP address, usercode, and password are passed. Files collected by NUL are exported to UNISYS central engineering from CMPTransport. The exporting of files, therefore, is important because it is the only way the system has a way of collecting data from NUL. The operating environment is so encapsulated, that it prevents outside access, and therefore to be able to show the desired product, data must be exported. If the answer to inquiry 3F is no, another inquiry is made as to whether or not the CKNUL box (item 11B) has been checked (item 3G). If the answer to inquiry 3G is yes, connector A gets an XML files name from input folder (item 3L). The program will reference this input folder by getting a list of all XML files that are in the input folder for subsequent processing. Next, another inquiry is made (item 3M) as to whether or not the file name in the input folder is valid. If the answer to inquiry 3M is no, the sequence will proceed to FIG. 3D. If the answer to inquiry 3M is yes, one proceeds to FIG. 3C. If the answer to inquiry 3G is no, a process to get the express server (FIG. 13) password from the registry is initiated (item 3I). This is the password that enables one to access the collection point for NUL XML files on the other side of the firewall. Next, the program will call IMPORTNUL_XMLFILES (item 2G) passing the parameters input directory, NUL IP address, usercode, and password which will copy the NUL XML files from the Express Server (FIG. 13).

[0198] Referring now to FIG. 3C, which begins with a call to OPENXMLANDFINDVERSION (item 3N), which passes the parameter of the XML file name. The file is opened up and items are examined to see if it is a valid version of the file, and that the files have not been processed before. Next, an inquiry is made (item 3O) to check if the XML file open was successful. If the answer to inquiry 30 is no, the XML file is moved to a “not processed” folder (item 3S). If the answer to this inquiry is yes, a call to READXMLFILE is made (item 3P), which reads in the file and processes all the items within the file. READXMLFILE also, at that time, updates the database 1H in FIG. 1. The call to READXMLFILE is illustrated further in FIG. 8.

[0199] Next, another inquiry is made (item 3Q) to check if READXMLFILE was successful. If the answer to inquiry 3Q is no, the XML file is moved to a “not processed” folder (item 3S). If the answer to inquiry 3Q was yes, item 3R moves the XML file to the archive folder (item 11D), which has been identified by the user during set up of the program. This is followed by a connection to FIG. 3D.

[0200] Referring now to FIG. 3D, which begins with an inquiry (item 3T) as to whether there are more files in the input folder 1F. If the answer to inquiry 3T is yes, a process gets the next file name (item 3U), and goes back to the top of the loop via FIG. 3B at item 3M, and continues processing. If the answer to inquiry 3T is no, the procedure exits at item 3V.

[0201] Now referring to FIG. 4, which illustrates the process for importing XML files, IMPORTXMLFILES 2F, and begins with a procedure entry point (item 4A), which expects to receive parameters: current directory, IP address, userid, and password. Next a call to a procedure MAKECONNECTION is made (item 4B), which establishes a physical connection to a server that passes the parameters: IP address, userid, password, and a constant “CONNECT_TO_SERVER” for subsequent processing by MAKECONNECTION. Next, an inquiry is made (item 4C) to check if the connection is established. If the connection was not successful (no) in inquiry 4C, the procedure exits at item 4E. If the connection is established successfully (yes) at inquiry 4C, a procedure to call MOVEXMLFILES is initiated (item 4D) passing parameters: current directory and IP address. The call on MOVEXMLFILES moves files from the server on the other side of the firewall into the input folder 1F. The procedure then exits at item 4F.

[0202] Now referring to FIG. 5, which illustrates the process for importing NUL XML files, IMPORTNUL_XMLFILES 2G, this begins with a procedure entry point (item 5A), which expects to receive parameters: current directory, IP address, IP usercode, and IP password. Next, a procedure to call MAKECONNECTION is made (item 5B) that passes the parameters: IP address, IP usercode, IP password, and “CONNECT_TO_SERVER” for subsequent processing by MAKECONNECTION. Then, an inquiry is made (item 5C) to check if the connection is established. If the connection was not successful (no) in inquiry 5C, the procedure exits at item 5F. If the connection established successfully (yes) at inquiry 5C, a procedure to set the current directory to “SENTINEL” is initiated (item 5E). Sentinel is the directory on the Express Server (FIG. 13) where all the XML files from NUL are stored. Next, a procedure to call MOVEXMLFILES is initiated (item 5G), which moves all the files from the server to the input folder and passes the parameters: current directory, and IP address. The process then exits at item 5H.

[0203] FIGS. 6A, and 6B illustrate the procedure for exporting XML files, EXPORTXMLFILES 2H.

[0204] Now referring to FIG. 6A which begins with a procedure entry point (item 6A), which expects to receive the parameters: current directory, PROXY IP address, PROXY usercode, and PROXY password. Next, the Express Server IP address is set (item 6B). Next, the express server usercode and password are set (item 6C). An inquiry is then made (item 6D) to ask if there is an XML file in the current directory. If there are no files in the current directory (no), as asked by inquiry 6D, the process then exits at item 6F. If there is an XML file in the current directory (yes), as asked by inquiry 6D, a procedure to call MAKECONNECTION (item 6E) is initiated, which establishes the physical connection to the express server, and pass the parameters PROXY IP address, PROXY usercode, PROXY password, and “CONNECT_TO_PROXY”. Another inquiry is made (item 6G) which examines whether or not the connection to the PROXY server is successful. If the connection to the PROXY server is not successful (no), the process exits at item 6J. If the connection to the PROXY server is successful (yes), a connection to EXPRESS Server via PROXY is established (item 6H). The EXPRESS Server directory is then set to “SENTINEL” (item 6I). This enables us to transfer the files to the SENTINEL directory on the EXPRESS Server. The process is then continued at item 6K in FIG. 6B.

[0205] Referring now to FIG. 6B, which begins with a loop (item 6K) that will process all the files that are in the input folder 1F (FIG. 1). A procedure to get the name of the XML file, 1B, from the current directory is then processed (item 6L). The file is then transferred using FTP to the EXPRESS Server (item 6M). The next file in the current directory is then found at item 6N. An inquiry is then made to see if there is a file present in the current directory (item 6O). If there is a file present (yes), the procedure loops back to item 6K, and goes through the process again. If there is not a file in the current directory present, the process exits at item 6P.

[0206] Now referring to FIG. 7, which illustrates opening of, and finding a version of XML files and begins with a procedure entry point (item 7A), which expects to receive the parameter filename. The filename is then opened as specified by filename (item 7B). An inquiry is then made (item 7C) to check if the files referenced by the filename are in use. If the file is in use (yes), the process exits passing a parameter back saying that the file is locked (CFILELOCKED) at item 7G. If the file is not in use (no), a procedure for XML.LOAD file is processed (item 7D), which actually reads and loads the XML file for processing. Another inquiry is then made (item 7E) to see if the file loaded correctly. If the file did not load correctly (no), the process exits passing a parameter back with an error code (CXMLLOADFAILURE) at item 7H. If the file did load correctly (yes), verification is made (item 7F) to check if the TALLY field within the file is valid. If the TALLY field is not valid (no), the process exits (item 7I), with an exit code of CXMLTALLYFAILURE. If the TALLYFIELD is valid in inquiry 7F, a procedure to get the version information from the XML control block is processed (item 7J). The process then returns, to the caller, a return code of success at item 7K.

[0207] FIGS. 8A, 8B, and 8C illustrate the procedure for reading an XML file, READXMLFILE 3P.

[0208] Referring now to FIG. 8A, which begins with a procedure entry point, and is followed by an inquiry to check if the XML file is a duplicate (item 8A). If the file is a duplicate (yes), the process exits with an error code of CDUPLICATEXML (item 8E). If the XML file is not a duplicate (no), procedure UPDATESYSTEMINFOTABLE is called (item 8B) which will update the SystemInformation table in the Unisys proprietary engineering database with the system information contained in the XML file. Next, procedure UPDATEPARTITIONINFOTABLE (item 8C) is called which will update the PartitionInformation table in the Unisys proprietary engineering database with partition information contained in the XML file. An inquiry is then made (item 8D) to check if the system configuration information is available. If the information is not available (no), the process proceeds to FIG. 8B at item 8G. If the information is available (yes), the process proceeds to FIG. 8B at item 8F.

[0209] Referring now to FIG. 8B. Since system configuration information is available from FIG. 8A, item 8D, then a procedure to call UPDATECONFIGURATIONINFOTABLE is processed (item 8F). This transfers all information out of the XML file that pertains to configuration information into the ConfigInformation table in the Unisys proprietary engineering database 1H. An inquiry is then made at item 8G, whether the system inventory information is available. If the information is available (yes), a procedure to call UPDATEHWINVENTORYTABLE is processed (item 8H). This moves the information from the XML file that pertains to INVENTORY into the inventory table in the Unisys proprietary database 1H. If the information is not available (no) in inquiry 8G, an inquiry is made to check if the EXCEPTIONINFO is available at item 8I. Inquiry 8I checks the EXCEPTIONINFO. If the EXCEPTIONINFO is available (yes), the process proceeds to FIG. 8C, item 8J. If the EXCEPTIONINFO is not available (no), the process proceeds to FIG. 8C, at item 8K.

[0210] Referring now to FIG. 8C, which begins with a call to UPDATEEXCEPTIONLOGTABLE (item 8J), which moves all the exception log information from the XML file to the exception log table in the central Unisys database. Exception information could include messages regarding the failure of the Availability Monitor program scan process to log in to a service processor or partition. Next, a call is made on the UPDATEEVENTLOGTABLE (item 8K), which moves all the information out of the XML files that pertains to the events to the event log table in the Unisys central engineering database. An inquiry is then made to determine if there is another partition with information available in the XML file (item 8L). If the answer to inquiry 8L is yes, proceed to FIG. 8A, item 8C. If the answer to inquiry 8L is no, another inquiry is made to check if there is another system available in the XML file (item 8M). If the answer to inquiry 8M is yes, proceed to FIG. 8A, item 8B. If there is no more information available in the XML file (no), the procedure exits at item 8N.

[0211] FIGS. 9A, 9B, and 9C show the procedure for moving XML files, MOVEXMLFILES 4D.

[0212] Referring now to FIG. 9A, which begins with an entry point into the procedure (item 9A), expecting parameters: current directory, and IP address. Next, the first XML file on the remote server is found (item 9B). An inquiry is then made (item 9C) to check if there is an XML file available. If there is no XML files available (no), the procedure exits at item 9C. If there is an available XML file (yes), a loop looking for XML files is begun at item 9D. The loop then proceeds to FIG. 9B, item 9F.

[0213] Now referring to FIG. 9B, which begins with a process to copy XML file from the server to the current directory or to the pointer where the current directory is, based on the parameter that is passed in (item 9F). This is followed by an inquiry (item 9G) to check if the file copy was copied successfully. If the file copy was not copied successfully (no), the sequence proceeds to FIG. 9C, item 9J. If the file copy was successful (yes), the timestamp of the file is changed in the current directory (item 9H) to reflect the current time that the file was moved. The XML file is then deleted from the server at item 9I, which then proceeds to FIG. 9C, item 9J.

[0214] Referring now to FIG. 9C, which begins with a process to get the next XML file name from the server (item 9J). An inquiry is followed to check if there is an XML file available (item 9K). If there is a file available (yes), the process continues at FIG. 9A, item 9D to begin looping to look for XML files. If there are no files available (no), the procedure exits at item 9L.

[0215] Referring now to FIG. 10, which illustrates a “make connection” process MAKECONNECTION 6E, and begins with a procedure entry point (item 10A) by expecting parameters: IP address, userid, password, and CONNECTION_METHOD. CONNECTION_METHOD can be CONNECT_TO_PROXY or CONNECT_TO_SERVER. An inquiry is then made (item 10B) to check what the connection method is. If the connection method is CONNECT_TO_PROXY, CONNECT_USING_PROXY or CONNECT_TO_SERVER, a process is set to open connection INTERNET_OPEN_TYPE_PRECONFIG (10D), which is an FTP open connection function. The process 10D then turns to inquiry 10E to check if the open connection was successful. If at 10B, the connection method is CONNECT_USING_PROXY, the connection is opened with INTERNET_OPEN_TYPE_PROXY (item 10C). INTERNET_OPEN_TYPE_PROXY is an FTP function. An inquiry is then made to If the open connection was not successful (no), the process exits with an error at item 10F. If the open connection was successful (yes), a CONNECT_TO_INTERNET is issued, which is an FTP function (item 10G). This connection is made using the IP address, userid, and password that were all passed in. Another inquiry is then made to check if the connection to the Internet was successful (item 10H). If the Internet connection was successful (yes), the procedure exits at item 10I. If the connection to the Internet was not successful (no), the procedure exits with an error at item 10J.

[0216] Now referring to FIG. 11, which shows a window screen snap shot of the Cellular Multi Processor (CMP) Transport screen, and the user inputted fields within. Checkbox 11A enables the copying of XML files NUL from the server into the input folder when it is checked. This is defined in further detail in field 11C. Checkbox 11B enables the copying of XML files from the Express server into the input folder as defined in 11C. Textbox 11C specifies the particular folder that the XML files will be moved to from the server and where they will be found for subsequent processing. Textbox 11D specifies the folder where the XML files will be moved to for archiving after they are processed. Command button 11E causes the CMP Transport to process “Update Database Now”. Textbox 11F specifies the Internet Protocol (IP) address of the server. Textbox 11G specifies the User ID required to access the server at the IP address in 11F. Textbox 11H specifies the Internet Protocol (IP) address of the Express server. Textbox 11I specifies the User ID required to access the Express server at the IP address in 11H.

[0217] Described herein has been a system and method for scanning and returning availability data and stability data utilizing an Availability Monitor program in a Service Processor, which supports a Cellular Multi-Processor, which manages several different Operating Systems (partitions). The availability and stability data is transported to a central engineering database for subsequent analysis. The stability data is secured from non-secure sites through a firewall. XML files are imported via the Internet to a central engineering group where information as to system and application software can be viewed as to starts, stops, errors, etc, which indicate the time and source of the events involved.

[0218] Though one embodiment of the invention has been described, other embodiments may be used which still are encompassed by the attached claims.
