DB2 error message SQL1224N occurs on AIX

Problem or error: The following DB2 error message occurs on AIX: SQL1224N A database agent could not be started to service a request

Solution: If the database was running when the user received the error, and the maximum number of agents was not exceeded, then the system may have run out of shared memory segments per process.

If the database is on the same machine where the Unica Campaign server is installed and the platform is AIX, a possible solution is to have the database administrator catalog the database through loopback, using TCP/IP, instead of a shared memory connection. TCP/IP connection avoids the shared memory limitation on AIX.

See the DB2 documentation for complete details on this error.
