DORMANCY(mmmm) specification

Setting (mmmm) too high will increase delays in JES2 processing on this member. Setting it too low will create excessive contention with other members in the configuration.

A good initial value for a particular member is the sum of:

All HOLD= values for all other members in the configuration.
The length of time it takes to read and write the checkpoint. If the checkpoint data set resides on DASD, a good initial estimate for calculating this length of time on DASD is 15 (that is 0.15 seconds per member to both read and write the checkpoint).
If the checkpoint data set resides on a Coupling facility structure, checkpoint I/O is even quicker, because it does not have to set the hardware RESERVE or read the change log.

The default for the DORMANCY(mmmm) specification is 100 (1 second).
