In the Space user menu of the DBA Cockpit, you can find, among other things, a display of the OMS heap usage since the last start of the liveCache Monitoring.
Open the DBA Cockpit (transaction code DBACOCKPIT) and choose .
The OMS Heap configuration parameters are displayed: OMS_HEAP_LIMIT, OMS_HEAP_THRESHOLD, OMS_HEAP_BLOCKSIZE, OMS_HEAP_COUNT
The current values of the following memory areas are displayed: Data Cache, Converter, maximum heap usage, and system heap
The system displays information on OMS heap usage.
