Benefits of a diagnostic run

The advantages of performing a diagnostic run are:
  • It collects diagnostic information automatically, thus allowing you to get CICS back into production quickly.
  • When CICS failed, a system dump may not have been produced. A diagnostic run provides one.
  • If the diagnostic run is not able to retrieve all the records from the CICS system log, the last record it retrieves shows the point at which the log became unreadable, and may indicate the cause of the problem.
  • A diagnostic run allows you to capture a dump of the MVS logger address space. See Getting dumps of the MVS logger and coupling facility address spaces.
