Description

CheckPoint PAGe THReshold.

The new fullword CPPAGTHR parameter can be set to force a checkpoint when the number of pages written to the current stream hits the threshold.

If the threshold is small and it's hit while the checkpoint PST is writing out subtran checkpoint data, the threshold is ignored. If the checkpoint fails (must be non-subtran) it is not retried.

If the parameter is reset below the number of pages written to the current checkpoint stream, a checkpoint is immediately forced.

The default for CPPAGTHR is 0, meaning that it is not in use.
