> I have a couple of unrelated Oracle 8.1.7 databases that occasionally

: 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?
