Re: When will ADRDSSU start to ENQUEUE on data sets?

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,<snip>
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
delete the data set and re-create it during that time (1.5 hours after the
dump job starts). It might be the cause of ADR321E.
