Managing history files across MVS systems without shared DASD

Views can be used for easy access to fault entries in more than one history file. However, this easy access is only possible when all history files in a view are accessible from the same MVS™ system.

If the systems share DASD, they can simply use a common history file. Two other solutions are provided for sending fault entries from the system on which the fault occurred to another system for analysis:
  • The first solution uses the Notification user exit and requires no manual intervention. See Automated implementation.
  • The second solution uses the Formatting user exit to transmit fault entries "on demand" during interactive reanalysis. See On-demand implementation.
