ORA-4031 errors frequently and users are having locking / hanging problems. The ORA-4031 errors show SQL AREA.


ORA-04031: unable to allocate 4000 bytes of shared memory ("shared pool","select audit$,options from p...","sql area","seg:kggfaAllocSeg")

ORA-04031: unable to allocate 4096 bytes of shared memory ("shared pool","SELECT EVENT_CASE_ID FROM ...","sql area","kgghteInit")

Looking in the ORA-4031 trace shows (in this example) 400MB allocated to SQL AREA which was the bulk of all shared pool allocation.


cursor_space_for_time = true (non-default setting)
