Brokers that handle large numbers of retained
subscriptions or publications can use up all the IRLM storage that is allocated
by default for
DB2 locks. This might
cause problems when you try to restart the broker.
The following actions
might help stop this happening.
Note: There might be a slight (approximately
1 to 2 percent) performance degradation when you run with PC=YES.
See DB2 Universal Database for OS/390 and z/OS Version 7 Administration
