If you are missing the files “updateJVMArgs.py” and “ccmUpdate.sh” resp “ccmUpdate.bat” aftre you installed IBM Connections 4.5 CR1, then you might have forgotten one step.
After unpacking the ZIP file with all CR1 fixes you find one additional ZIP file “45-CR1-CCM-OPTIONAL-UPDATE-UNZIP-AND-PLACE-JAR-IN-FIXES-DIRECTORY.zip” which also need to be unzipped.
The resulting fix “LO75060-IC4500-CR01-CCM.jar” also needs to be installed with the Connections update manager.
Afterwards the missing files should be available in the ” /opt/IBM/Connections/addons/ccm/ccmDomainTool/” directory.
