Important tip on Sametime installs - increase the JVM heap size for Installation Manger

I wanted to mention this tip as I have just finished my part of a 80+ Sametime server environment and this tip helps the installer work so much better (including helping it not to crash "out of memory" sometimes):

  • Increase the JVM heap size for the Installation Manager
  • Close Installation Manager
  • Go to the Installation Manager install directory (C:\Program Files\IBM\Installation Manager\eclipse)
  • Add the line "-Xmx1024m" to IBMIM.ini
  • Run the offering launchpad again to invoke the installation
Thanks to Tony Payne and Andy Yiu from IBM for this tip.


  1. This is only for windows installs....right?

  2. It is recommended to be done on ALL deployment types, so no, it's not only for windows.
