Wright (wrightc@dtcweb.com) ********************************************************************** A warning to all who use OS/2's Feature install subsystem (to install TCP/IP 4.1, Java 1.1, etc...) For those who have not yet noticed, this WPS-based system allows the user to uninstall an application by opening its install object (under \OS2\Install\Installed Features,) selecting components to uninstall, and clicking the uninstall button. IBM sometimes recommends this procedure before installing upgraded versions of products. I strongly recommend AGAINST using this "Uninstall" function. I recently tried to uninstall Java 1.1.6 this way. Apparently it uses the system's INI files to locate certain objects and files to delete. If you have errors in your INI files, such as cross-linked file handles or possibly shadows to improper files these files can be unintentionally deleted during the process. This has occured on two different systems here, resulting in the loss of hundreds of megabytes of important data. I would appreciate hearing from others who have had this happen. If I can determine that this is a fairly common problem I will send a report to IBM about it. ---------------------------------------------------------------------- To subscribe, unsubscribe, or for more information on WarpCast, visit: http://www.warpcast.com/ ----------------------------------------------------------------------
