Local fix

. If this leads to restart issue where Db2 cannot be brought

up then special usermod will be required to expand pool

to allow for recovery processing.

The USERMOD code changes the storage size, which Db2 uses for

Db2 internal control block PDA, from 2GB to 16GB so that

Db2 can successfully restart to process log records.



To avoid the storage pool from exceeding limit, customers should

monitor for the following message and take action:

.

DSNJ016E csect-name WARNING - SYSTEM CHECKPOINT PROCESSOR MAY

HAVE STALLED. LAST CHECKPOINT WAS TAKEN date-time.

...

No local fix to avoid the overlay that can occur.
