Lotus Sametime Entry 8.5.1 and BES Express 5.0.x co-existing on the same Domino server

I was confronted with two issues when installing Sametime Entry 8.5.1 after the BES Express server was installed on the Domino 8.5.2 FP2 server.

When I installed Sametime Entry 8.5.1 over Lotus Domino 8.5.2 FP2 today I got an error message stating: “Xsp Initialization error – Could not get JVM environment”.  After a little bit of searching I found out the following:

The problem turned out to be that the BES Express installation was effectively setting any JVM to be disabled in the Domino server’s notes.ini.   The setting that BES Express changed in the Notes.ini was:

HTTPDisableJVM =1
I changed the value to 0 and the error message went away.

However,  despite the change the STaddin task was still not loading when Domino started up.  I checked the domino log and I noticed the following error message:

05/25/2011 11:31:20 AM  HTTP JVM: JVMJ9GC027E Malformed option: ‘-Xmx64sM’

05/25/2011 11:31:20 AM  HTTP Server: JVM: Missing entrypoint in JVM runtime library.05/25/2011 11:31:21 AM  HTTP Server: Shutdown

I did a “sh conf http*” on the Domino console and saw that my HTTPJVMMaxHeapSize was set to 64M.  I fixed this by increasing the HTTPJVMMaxHeapSize to 128M  and restarted the server. Everything is working now. What a happy day for me. : )
