Reducing false contention

If false contention becomes a problem, try the following:

Reduce the amount of real lock contention in your applications, if possible
Specify a larger size for the lock structure and manually rebuild it
Ensure the MAXSYSTEM parameter of the Couple Data Set utility is not too large for the number of members in your Parallel Sysplex®
A MAXSYSTEM value of 7 or less allows you twice as many lock entries as a MAXSYSTEM value of 8, as shown in Table 1.
