In case of problems, a PMR, et.al. it is sometimes necessary to verify, that you have installed all WAS Fixpacks and patches requireed by a specific product. Fortunately, WAS provides a handy command line tool for that.

Just switch to the Websphere/AppServer/bin directory like

  cd /opt/ibm/WebSphere/AppServer/bin

and call "./versionInfo.sh  -maintenancePackages" (without the "-maintenancePackages" only the WAS version and the installed Fixpacks are displayed. With "-maintenancePackages" the installed patches are also shown):
