One of our third party applications gave us the following message:

ORA-04031: unable to allocate 4192 bytes of shared memory

Environment is Oracle 8.1.7 on AIX 4.3.2

The output from "select * from v$sgastat showed about 3 mb free out of a total of 40 mb of shared pool. I increased the size of shared pool to 60 mb and started to watch the "shared pool"/"free memory" value in v$sgastat. It seems to vary between about 3 and 11 mb.

What is the application likely to be doing that requires it to allocate shared pool?
How do I know when I have the shared pool value in init.ora set high enough so that I won't get the ORA-04031 errors?
Is there any other init.ora parameter I ought to be looking at here?

Thanks,
Peter Schauss
