activation, SQL1224N will be returned, and the instance will be
brought down, instead of the expected graceful SQL10003C which
would not cause an instance abend. The following symptoms will
be seen:

| Local Fix: |
Ensure there are no memory allocation errors during a database
startup. The error (SQLO_NOMEM_BPH) is a consequence of a
misconfigured operating system (shared memory kernel
configuration parameters too low), or a lack of real memory. |
