System Restrictions for Deferred Checkpoint/Restart

The following restrictions apply when submitting a job for deferred checkpoint/restart:

Jobs specifying nonpageable storage (ADDRSPC=REAL) require an area of storage identical to the storage originally requested at the time the checkpoint is taken and starting at the same address.
The link pack area modules in use at the time the checkpoint is taken must reside in the same storage locations for the job submitted for deferred checkpoint/restart.
Any time a change link pack area (CLPA) is required, the locations of modules in the link pack area (LPA) might change without any changes to the LPA modules themselves. This prevents the restart from any checkpoint taken prior to the IPL in which the CLPA is required.
Changes to hardware features and other system reconfigurations may require a CLPA. Review the instructions included with any such change carefully to determine if a CLPA will be required.
The nucleus must not be changed between checkpoint and restart.
If the required storage is not available, it may be for one of the following reasons:
The link pack area expands into the required storage
The system queue area expands into the required storage.

If either of the above conditions occurs, contact your system programmer for a respecification of the system parameter to modify the area size and repeat initial program loading using the new value.
