CSVH0957E Problem(s) were found with data sets in the APF list.

Explanation
 Check CSV_APF_EXISTS found a problem in the
APF list.
 CSVH0955I has been placed in the message buffer to
describe the APF list entry error and condition that caused the exception.
 A
potential system integrity risk exists when a data set cannot be allocated
using the criteria specified in the system APF list. If this data
set were created it would be considered APF-authorized.
  The error is one of the following conditions: DS is alias
The data set name is an alias of another data set.  An APF list entry that has the alias of a data
set rather than the real data set does not APF-authorize the data
set.

DS is migrated
The data set is migrated. APF-authorized data sets should not
be migrated because they might not be restored to the same volume.
DS is SMS-managed
The data set is SMS-managed, but the APF list entry specified
a volume.  If the APF list entry represents
a SMS-managed data set but has specified the volume parameter, the
data set would not be authorized if it were moved to a different volume.
 In order for DFSMShsm to verify APF-authorization properly, the APF
list entry must indicate that the data set is SMS-managed.

DS not SMS-managed
The data set is not SMS-managed, but the APF list entry specified
a SMS-managed data set.  This entry does
not result in the cataloged data set being APF-authorized.  The APF
list entry must identify the volume that contains the data set when
a data set is not SMS-managed.

Volume not found
The specified volume could not be found.
DS not found
Indicates that either the data set was not on the volume specified
in the  APF list entry or the data set name is an alias.  When the APF list entry indicates a *SMS* volume,
the catalog entry for the data set is in error. If this data set were
to be created it would be considered APF-authorized.

Allocation failure
The data set could not be allocated.

System action
 This check is performed against the current APF
list.  The system continues processing.

Operator response
 Report this problem to the system programmer.

System programmer response
 Correct the error for each APF list
entry reported by CSVH0955I in the message buffer.

Problem determination
 See CSVH0955I in the message buffer which
lists the APF list entries that are in error.
 To see additional
messages that describe an allocation failure, use the MODIFY hzsproc command
to request debug mode and run the check again. There might be a temporary
problem such as the data set's being in use by another job.  You can use the following commands:

F hzsproc,UPDATE,CHECK(IBMCSV,CSV_APF_EXISTS),DEBUG=ON

F hzsproc,RUN,CHECK(IBMCSV,CSV_APF_EXISTS)

 Look
in he message buffer to see diagnostic messages, like HZS1093I, that
describe an allocation failure.
