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.
