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 work cause I don't want to change the way other
people use DSS. So my rexx must be able to process any data set list syntax
DSS recognizes.
Thanks.

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. Changing the job by adding build-include-list step,
before calling ADRDSSU, which uses REXX to call the IGGCSI00 Catalog
Search
Interface and built an explicit filter list (FILTERDD), reduced that wait
time to
2 minutes.
If you need to ENQUEUE on the dataset, just add
//DD001 DD DISP=SHR,DSN=dataset1
etc
to your backup JCL.

Hi,got
We encountered a problem on our production system.
A job was using DSS to backup a lot of data sets (logical dump) and we
ADR321E for one extended format PS data set: the data set was not on thewill
supposed volume.
This job will run more than 3 hours and we found out that another job
delete the data set and re-create it during that time (1.5 hours afterthe
dump job starts). It might be the cause of ADR321E.<snip>
