The Java heap size must always be defined INDIVIDUALLY depending on the configuration of the server and your UMS environment, but it must be less than the amount of available physical RAM. General recommendations can be found in the Oracle article Tuning Java Virtual Machines (JVMs); see also the -Xmx
option there.
Note also the following:
- All heap size changes are at your own risk! Change the heap size only if you know exactly what you are doing. In the case of improper configuration, the ICG server will be unable to run.
- Reducing the memory may affect the function of the ICG and is NOT recommended.
- During the ICG update, the heap size value is set to the default. Therefore, you have to adapt it again.
