Explanation
The user requested control be given to the installation-wide
exit so a new block size for the data set
dsname could
be specified during recall or recovery processing. However, the existing
block size is used. If the
return-code is nonzero,
the user requested no reblocking of the data set. If the
return-code is
0, reblocking does not occur as a result of one of the following conditions:
- The ESTAE macro failed for the installation-wide exit (message
ARC0304I is issued).
- The installation-wide exit resulted in an abnormal end (abend)
(message ARC0004I is issued).
- The user requested a block size larger than the maximum record
size (32760).
- The user requested a block size smaller than the existing record
size.
- The block size did not change from the existing block size.
System action
Recall or recovery of the data set continues
with the existing block size. DFSMShsm processing continues.
Programmer response
If the reblocking does not occur because
of an installation-wide exit abend, the installation-wide exit is
disabled until the problem is corrected and the installation-wide
exit control is reestablished by issuing a SETSYS command.
