CA 7 was recently upgraded from 11.3 to 12.1. It seems jobs were executing correctly but we recently noticed that some jobs sporadically have the following message:
SM50-14 DATASET OUT OF SPACE
25196 024510 REPL,nnnnnnn,JCLID=254
The message indicates that the dataset is out of space. Current size was only 1 cylinder. To address this, the CA 7 override library needs to be increased to a larger size.
