Cause

java memory too low

Environment

Unified Infrastructure Management (Any version)

Maintenance_mode probe

Resolution

-Verify if error is displayed in the maintenance_mode log :ORA-04036: PGA memory used by the instance exceeds PGA_AGGREGATE_LIMIT, if yes, work with Oracle DBA on the Oracle-related issue and fix increasing the Oracle PGA memory, to fix it. 

  • Check the ems and maintenance_mode and spectrumgtw probes, if the java memory min/max is too low so increase them to 2048/4096. And with spectrumgtw at 1024/2048.
  • Then a cold start (Deactivate-Activate) such probes.
  • Verify if no errors whatsoever seen in those probes any longer even at loglevel 5.

 

Additional Information

  • The status of a node in maintenance, e.g., white icon, should not be checked in IM as that is legacy behavior not related to OC for the state of the node.
