Description:
We are getting errors, especially in our oclc_server logs like the following:

Oracle error: handle_connection
ORA-04031: unable to allocate 27504 bytes of shared memory ("shared po

Our current setting is:

SHARED_POOL_SIZE=268435456 #256M
SHARED_POOL_RESERVED_SIZE=13421772 #13M

Should these be upped?

Resolution:
From site: We believe that the problem here may have been a system setting. In particular, the semsys:seminfo_semmsl setting.

We had to up our number of Oracle processes to 1000 and did not make the corresponding change to the system configuration. We have since upped the semsys:seminfo_semmsl number and rebooted the machine.
