CasePoint OS/2 1.3 R1 Release Notes Important Installation Notes ---------------------------- CasePoint OS/2 is an OS/2 Presentation Manager program that can be installed to OS/2 version 2.0 and above. CBR Express OS/2 is not yet available, but CBR Express/Windows can be used to build and maintain case bases for CasePoint OS/2. CBR Express/Windows can be run under WIN-OS2. When performing a re-installation of CasePoint onto a network, ensure that the Overwrite Files option is selected in the Install program. RDM Installation: 1. If CBR Express and CasePoint will be run on the same machine at the same time, make sure that the "tafPath" variable in the file CBRX.INI for CBR Express and CBRX.OS2 for CasePoint, points to the same directory. 2. If CasePoint will be installed on a network, all users must be given full rights to the TAF directory. This is the directory specified by the "tafPath" variable in the CBRX.OS2 file. Full access is required because RDM will attempt to create, read, write, and delete the transaction log files in this directory for all users. Without full access, users will experience locking problems. SQL Installation: 1. CasePoint 1.3 R1 provides database support for both Oracle 6 and Oracle 7. However, CasePoint is currently configured to use ora6.dll. For Oracle 7, this file is only distributed with the Client/Server version of Oracle. Additions to the current OS/2 version of CasePoint -------------------------------------------------- The following changes have been incorporated in this version of CasePoint OS/2: 1. Upgrade from level 1.3 to 1.3 R1. 2. Support for case bases extended to include DB2/2, Oracle and SQL Server, in addition to the previous support for RDM (Raima Data Manager). 3. Conversion program to port case bases from RDM to DB2/2. 4. Support for read-only case bases, on network or CD-ROM. 5. Support for re-directing unresolved cases to a different path when the case base is on a read-only path. 6. Support for controlling concurrent DDE sessions to multiple instances of CasePoint. 7. Supplied DDE Client examples in C and WordPerfect. 8. Support for customizing text in the CasePoint title bar. Generic Additions to CasePoint 1.3 R1 from CasePoint 1.3 -------------------------------------------------------- New functions have been added to provide more information about the case base. These functions allow a cooperating application to retrieve information about actions and questions for a given case. The addition of these functions completes the API for retrieving information about the data in the case base. Refer to the CasePoint Application Programming Interface User's Guide for more information about these functions. Problems Fixed in CasePoint 1.3 R1 ---------------------------------- A number of problems regarding question ordering in the search window have been corrected. The previous release of CasePoint would display a maximum of 100 questions with no consideration given to the questions of the highest scoring cases. This is no longer the case. Furthermore, no consideration was given to answered questions as well. This too has been corrected. Toolbar buttons upon being pressed will now display a status line message describing their functionality. Ampersands in lieu of underscores now appear in case, question and action titles in the search window and the Text Question dialog box. In the Standard Version, unresolved searches can now be saved via either double-clicking on the icon, clicking on the pulldown menu item, or using the keyboard shortcut. Known Problems in CasePoint 1.3 R1 ---------------------------------- A maximum of 26 case bases can be opened per invocation of CasePoint. Currently, we do not provide any example case bases with CasePoint for SQL. However, the installation program does not make this clear. If you would like to create these example case bases, CBR Express 1.3 is supplied with example .CDF files that can be used to import into an SQL database. See the CBR Express documentation and release notes for more information. CasePoint will need access to the resulting .CBS and .CBR files. For DB2/2, we provide a conversion program which can be used to port the case bases from RDM to DB2/2. There is a problem using DDE to perform searches to CasePoint when CasePoint is minimized. As a result, search scores can be incorrect. This is caused by an error in OS/2 low level functions, which has been reported to IBM. If the search window alone is minimized, then CasePoint avoids the problem by temporarily maximizing the window. If CasePoint itself is minimized then the scoring problem will occur, and can only be avoided currently by not minimizing CasePoint. Important notes about upgrading to CasePoint 1.3 R1 --------------------------------------------------- CasePoint 1.3 R1 and CasePoint 1.3 environments are fully compatible and nothing need be done to upgrade other than installation of the software. Differences between CasePoint OS/2 and CasePoint/Windows -------------------------------------------------------- 1. CasePoint OS/2 runs as a native 32-bit application under OS/2 Presentation Manager, as opposed to 16-bit under Windows. 2. CasePoint OS/2 supports extended filename formats for the High Performance File System in addition to the FAT file system. 3. CasePoint OS/2 supports the loading of case bases built using the Windows version of CBR Express. Support for an OS/2 version of CBR Express will be provided in future releases. 4. The CasePoint OS/2 extended browse facility can call programs in multiple environments: Presentation Manager programs including CMD and REXX files, Windows programs running under WIN-OS2, and DOS programs from the DOS box. 5. A new icon is provided for CasePoint OS/2 in the toolbar for "Text browse". This allows a browse of text (additional information) when there is also a graphic browse defined, so that two types of browse information are available to the user. 6. File associations for the extended browse facility in CasePoint OS/2 are defined in a CasePoint specific file, and must be set up by the user. To use this facility you must create a text file called ASSOC.OS2, which contains a header line containing the text [Extensions] followed by the list of file extensions that are to be associated with programs. These should be one per line, as follows : [Extensions] txt=e.exe ^.txt bmp=iconedit.exe ^.bmp cbd=c:\casepnt\casepnt.exe ^.cbd This file must be placed in the same directory as the CasePoint program. To change existing graphic browse entries, so that they make use of file association, use CBR Express to edit the graphic browse field and remove the name of the program executable from the page field. Then, specify the name of the file that is to be passed as a parameter to the target program. 7. The current version of CasePoint OS/2 supports case bases to be held in a RDM format database, DB2/2, Oracle or SQL Server. 8. Screen attributes are different for OS/2 and Windows. OS/2 Presentation Manager screen co-ordinates are based on 'bottom left' but Windows is based on 'top left'. This affects the start up parameter to set the application position and size, and the DDE window geometry calls for the CasePoint API. 9. For CasePoint OS/2, ToolBook browses will start from the first page, not from the name or number of a specific page. 10. The CasePoint Preferences file is named CBRX.INI under Windows, and CBRX.OS2 under OS/2. 11. The current version of CasePoint OS/2 now supports case bases held on CD-ROM or on read-only paths on a network. The Preferences dialog has been extended in the Standard Version to allow the user to specify the path where unresolved cases may be saved (this information is usually determined by the case base author and saved within the case base). 12. As there is currently no OS/2 version of CBR Express, case bases to be stored in DB2/2 must be created using the conversion program supplied with CasePoint OS/2. 13. The text in the title bar of CasePoint may be changed by editing the resource file and replacing the text of the resource IDS_TITLE_CAPTION. Refer to Chapter 3 of the CasePoint Application Programming Interface Guide for further details of performing this customization. 14. Multiple concurrent DDE sessions may now be performed with CasePoint as the DDE Server. The DDE Client application must control the starting and initialization of each CasePoint server to ensure the proper connection. 15. CasePoint OS/2 DDE Client application examples are now provided in C and WordPerfect for OS/2. The C example is called CLIENT.EXE (the C source file is CLIENT.C and a batch file COMPILE.CMD is provided to generate CLIENT.EXE). The WordPerfect example is a macro called DDESAMP.WCM. Both examples are provided as source files so that the contents may be modified. Further details of the examples are provided in Chapter 2 of the CasePoint Application Programming Interface User's Guide. 16. UserIDs entered into the Preferences dialog may consist of up to six alphanumeric characters. Under Windows, the limit is seven.
