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.
