Johnny,
You may want to look into using Concurrent Copy with your backups. That way
you won't lose datasets that are deleted after the start of the backup, and
the actual backup will be closer to a real point-in-time image of all the
datasets processed by the job.

Hello Johnny,
Does your backup job use generic dataset masks for the INCLUDE list?
Search the archives for earlier posts on DF/DSS using the older SVC26
interface to retrieve CATALOG data.
In one case here a job took 2 hours to build the dataset list before mounting
the first output tape.
Bruce,
Thanks a lot!!!
I must say, it's a great idea. We have lots of job runing hours to backup
data sets both in production and test environment and they all use generic
filter.
The possible performance gain is well worth doing and I will work on it
right now.
The rexx requires some
I think there might be one issue you also need to deal with. This is old
knowledge and I do not know if the limit still exists, but at one time DFDSS
could only handle so many control cards at one time. The generic allowed
you to handle 100's of files but specific data set backups had a
Yes, it exists.
We're using z/OS 1.7 and the limitation forced me to use FILTERDD. The
limitation is only for the SYSIN.

Hello
Hi,
We encountered a problem on our production system.
A job was using DSS to backup a lot of data sets (logical dump) and we got
ADR321E for one extended format PS data set: the data set was not on the
supposed volume.
This job will run more than 3 hours and we found out that another job will
There is a delay between the building of the list and actually backing up each
dataset on the list. Generally, an enqueue is not set at the time the list is
built - as you said, it may be hours before each dataset is actually backed up.
Do you run DSS natively or are you calling it from
