Managing standard diagnostic information

You can preserve documentation that can be helpful near the time of error.

Consider implementing normal operating procedures for the following tasks:

Preserving the z/OS console (syslog)
The z/OS® Console should be saved to view relevant system messages.
Preserving the JES JOBLOG
Preserve the JES JOBLOG to view relevant job-related messages.
Preserving the IMS master console log
The IMS Master Console Log should be saved to view relevant IMS messages:
Preserving the SYS1.LOGREC
The SYS1.LOGREC should be saved to view system failures logged internally.
Preserving memory dumps
Retain all IMS memory dumps generated at or near the time of a problem.
Preserving the IMS OLDS and SLDS
The IMS OLDS and SLDS should be saved in case IMS log analysis is required.
