Description
CPTYPE = {0 | 1}
Where:
| 0 | Enables transaction checkpoints only. |
|---|---|
| 1 | Enables the use of transaction and sub-transaction checkpoints. |
In a CPTYPE=1 run, two other significant checkpoint parameters are CPTIME and CPTS.
As long as all data sets and parameters are appropriately defined and requirements met within your job, you can reset back and forth between CPTYPE=0 and CPTYPE=1. In recovery-only job steps, only set CPTYPE=0, or allow CPTYPE to default.
The CPTYPE parameter applies to timed checkpoints, meaning those initialized by CPTIME. This parameter is not referenced during CHECKPOINT command processing.
If CPTYPE is set to 1, then DKUPDTWT must be set to 0.
