Issue/Introduction

CA-Disk backup jobs occasionally abend with S822 using REGION=8M, other abend with S878 using REGION=7500K.  

Will introducing NON_VSAM_XTIOT=YES relieve for CA-Disk backup jobs  the LSAQ?

That means, CA Disk would need to check whether NON_VSAM_XTIOT=YES is set and,

if so, specify the parameters "XTIOT", "UCB NOCAPTURE" and "DSAB-above-the-line" when dynamically allocating files to be backed up and process the data set with "DCBE LOC=ANY". 

The DSAB's in the LSQA are the problem because they're not freemain´ed at the end of the step, but only at the end of the job. 

Environment

Release : 12.5

Component : CA Disk Backup and Restore

Resolution

No, CA Disk does not use the "XTIOT", "UCB NOCAPTURE" and "DSAB-above-the-line" parameters , so setting NON_VSAM_XTIOT=YES would not help in these cases.
