The past weekend was packed with installations and upgrades. I’ve got a bunch of software to install for my self-education – servers like IBM WebSphere Service Registry and Repository (WSRR) made it to RedHat Enterprise Linux (RHEL) 5.5 whereas more developer-oriented solutions like ILOG JRules V7.1 or Friday’s latest release of IBM WebSphere Lombardi Edition V7.2 went to Windows 7. All worked fine. Almost.
When I went on to upgrading WID 7, it turned out that there’s a glitch with JRE. It showed up right after the upgrade and am still unable to figure out what went wrong.
The upgrade process begun with Installation Manager. Nothing unusual.
Update took a few quarters and WID was ready for a spin.
Easy stuff. I however run into an issue right after I’d restarted the IM. It ended up with a popup window and the following mysterious error message – No Java virtual machine was found?!
I’ve seen it before and I knew the solution was to correct appropriate startup file for IM – C:\IBM\InstallationManager\eclipse\IBMIM.ini. There’s -vm option that points to a JRE and it was incorrect.
Correcting it was as easy as editing the file and run up the IM again. The mystery is why it happened at all? Anyone?
