ORA-04031: unable to allocate 4200 bytes of shared memory

Smith, Ron L.

2005-03-03

Replies:
I have a couple of unrelated Oracle 8.1.7 databases that occasionally
getting the following error:
ORA-04031: unable to allocate 4200 bytes of shared memory ("shared
pool","unknown object","sga heap","state objects")=20

Flushing the Shared Pool does not help the problem. The size of the
Shared Pool has been increased several times, but doesn't appear to
help. Neither database is very busy.

One of the databases serves as a "Gateway" database between a 7.3.4 and
a 9.2 database just for connectivity. The other is just a straight
8.1.7 OLTP database.

Bouncing the database ALWAYS corrects the problem for several weeks.

Can anyone help be diagnose the problem?

Thanks!
Ron
