Description

You can specify a time interval, in seconds, during which new transactions, both User Language and IFAM are prevented from starting. If non-zero, the CPTS parameter gives in-flight transactions a chance to end before they are forced into sub-transaction wait. If all transactions end during the specified interval, a transaction checkpoint is taken instead of a sub-transaction checkpoint.The parameter applies only when sub-transaction checkpoints are activated: that is CPTYPE=1.

Note: When non multicursor IFAM updating threads are active the CPTS parameter may be ineffective, because for those threads transactions are always in progress.
