Issue/Introduction

The customer is planning to register over 1000 DASD volumes as disk volumes to be processed and has the following questions regarding maximum numbers during CA Disk processing: 
Is there any upper limit the number of DASD volumes or the number of data sets that can be backed up with one job by CA Disk? 
Is there any upper limit the number of DASD volumes or the number of data sets that can be deleted with one job by CA Disk? 
Is there an upper limit value of the number of SELECT commands that can be specified in the SYSIN-dd statement by CA Disk's ARCHIVE & SCRATCH processing? 
Would using a 'TABLE=...' member help?

Is there a maximum number of volumes or data sets that can be backed up with one job by CA Disk?

Environment

Release:
Component: DISKOS

Resolution

These numbers are really going to be limited by the amount of region the job has available. There is no internal limit check.
Using a TABLE will not help for that as the control blocks are built by the data in the TABLE.
