<number_of> out of memory exceptions

OMS out of memory exceptions : <count>


This message can occur for SAP liveCache technology only.

DB procedures failed due to too little memory in the OMS heap.

User Response

  • Look in the kernel log for more detailed information.
  • Check the OMS versions, and check how much space they occupy in the OMS heap, for example, by using the log files DBAN_OMS_VERSIONS.csv and DBAN_OMS_HEAP.csv.
  • Check the OMS heap and, if possible, increase the size of the heap.
