Java Heap Size

Hi,

I am trying to run one script, but getting error as below

Please advise how to increase Java Heap Size. It Development system for MDM, OS is Unix.

Please also advise how to check Java Heap Size.

Thanks & Regards,

Hi Aman

Could you refer the SAP KBA for the error message "Exception in thread "main" java.lang.OutOfMemoryError: Java heap space "

Hello Aman,

The OutOfMemory error was generated by the MDM application according to the error.

First I would like to recommend this note: 1289240 - How to deal with out of memory errors which explains the OOO errors in general. Maybe the issue is due to a memory leak, which will not be solved by simply increasing the heap size.

Anyway, the heap size can be increased in the Config tool -> click on the instance -> VM Parameters -> Memory tab -> set the initialHeapSize and the maxHeapSize to the desired (and same) value.

Best Regards,

Peter
