Symptoms


Error "ORA-04031: unable to allocate 4000 bytes of shared memory" could be displayed in different scenarios, here some of those:


Accessing Portal:

Portal pages show HTTP-404 errors after Portal has been in use for a couple of days.
At the same time, the following error is seen in the OC4J_Portal application.log file:

08/08/24 11:11:06 portal: [module=RepositoryServlet, ecid=<ECID>] ERROR: Repository Gateway
error: Database Error: ORA=4031 ORA-04031: unable to allocate 4096 bytes of shared memory ("shared
pool","select /*+ rule */ bucket, e...","Typecheck heap","kgghtInit")
ORA-06512: at "PORTAL.WWERR_API_ERROR_UI", line 233
ORA-06512: at "PORTAL.HOME", line 121
ORA-00604: error occurred at recursive SQL level 4
ORA-04031: unable to allocate 4000 bytes of shared memory ("shared pool","select /*+ rule */
bucket, e...","Typecheck heap","seg:kggfaAllocSeg")
ORA-06508: PL/SQL: could not find program unit being called
ORA-06512: at line 25

The database containing Portal is then restarted which allows Portal to continue working until the same error appears again.
