Explanation

A checkpoint was written to the IMS system log, as the result of one of the following:
  • A restart command
  • A /CHECKPOINT command
  • A /DBRECOVERY command
  • A /DBDUMP command
  • Automatic initiation by the IMS system logger
  • A completed XRF takeover by the alternate IMS system
Upon completion of restart, the restart type is provided. During termination of IMS, the shutdown completion message is issued. The values of yyddd/hhmmss, ctype, and rtype are:
  • yyddd/hhmmss is the time stamp that identifies the checkpoint.
  • ctype is the checkpoint type. Possible values are: *SIMPLE*, *FREEZE*, *DUMPQ**, *SNAPQ**, and *PURGE**.
  • rtype is the restart type. Possible values are:
    • COLD
    • WARM
    • EMERGENCY
    • BUILDQ WARM
    • *BUILDQ* EMERGENCY
    • *COLDBASE* EMERGENCY
    • *COLDBASE* *BUILDQ* EMERGENCY
    • *COLDCOMM* EMERGENCY
    • *COLDSYS* EMERGENCY

System action

Normal processing continues or IMS terminates, depending upon the checkpoint type.

For the IMS SHUTDOWN (DBCTL) COMPLETED form of the message, the DBCTL terminates. For the IMS SHUTDOWN (DCCTL) COMPLETED form of the message, the DCCTL terminates.

For the STATISTICS CHECKPOINT COMMAND COMPLETED form of the message, IMS performance statistics records are written to the system log. This checkpoint is not a restart checkpoint.

For the XRF TAKEOVER COMPLETED form of the message, some of the recovery functions might still be active. In this case, new transactions that are not in conflict with recovery processing are allowed to run in parallel with the recovery processing.

Programmer response

No action is required.
