You can use system settings and Db2 subsystem parameters to improve concurrency.

Estimating the storage needed for locks
You can estimate the amount of storage needed for locks.
IRLM startup procedure options
You can control how Db2 uses locks by specifying certain options when you start the internal resource lock manager (IRLM).
Setting installation options for wait times
These options determine how long it takes Db2 to identify that a process must be timed out or is deadlocked. They affect locking in your entire Db2 subsystem.
