Message data set contents

DFSMShsm allocates a message data set for a request once the FRBACKUP, FRRECOV or auto dump operation has been verified as eligible for processing. Therefore, messages indicating parse errors or termination prior to the ARC1801I or ARC1841I start message being issued are not placed in a message data set.

DFSMShsm prefixes each message written to the message data set with the date and time that the message was written to the data set, along with the ID of the host that wrote the message. The following format is used: yy/mm/dd hh:mm:ss Hx message-text where x is the host ID. Some messages appear multiple times in a message data set.
