Home -> Community -> Mailing Lists -> Oracle-L -> Determining library_cache usage
We get this error:
ORA-04031: unable o allocate 40048 bytes of shared memory ("shared pool","SELECT : SASOFPD.PD_DT, : ...","sqa area","text : kpp_extend") :-4031
when trying to run a monstrous 26.1kb query. Yes that is the amount of text. The one query involves 9 case statements, some nested in others and several involving more than 50 when clauses. It also has 8 sum(), over 200 to_date() and a group by clause... Don't ask.
My guess is that we are running out of library_cache when this beast is parsed out. Sound reasonable?
Also, does anyone know of a way to determine how much library_cache/shared_pool a session is using.
