Description

You can change the number of spins that can be taken when an MPLOCK is not available before going into wait.

Rocket Software recommends that you test the setting of the MAXSPINS parameter at your site. Increase the value of MAXSPINS, watching for a drop in the values of the LKWAIT and LKPOST statistics. When the values of those statistics stop dropping, that's an indication that you've found a good setting for the MAXSPINS parameter.
