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.
