CRS-07502

The Oracle Grid Infrastructure process 'string' failed to open the shared memory file <ORACLE_BASE>/crsdata/string/shm/string*.

Cause

The reason for this issue was one of the following:

  • The Oracle Grid Interprocess Communication (GIPC) daemon failed to start.
  • The GIPC daemon shared memory was deleted accidentally.

Action

(a) If the GIPC daemon is not online, then investigate to determine the reason and try to start GIPC daemon using 'crsctl start res ora.gipcd -init' command. (b) If the GIPC daemon is online, but the shared memory file does not exist, then:

  • An external process deleted the GIPC daemon shared memory file.
  • Restarting the Oracle Grid Infrastructure stack restarts the GIPC daemon and, upon GIPC daemon restart, the shared memory file is re-created.
