DFS2850E COLDSTART REQUIRED DUE TO GLOBAL ONLINE CHANGE

Explanation

An attempt to warm start or emergency restart this IMS system failed because a global online change was performed while this IMS was down. This IMS must have a cold start if:
  • This IMS was down during two or more global online changes.
  • This IMS was down during the last global online change and this IMS restart type conflicts with the last global online change that was performed.

This message is sent to the system console in response to a restart command such as /NRE or /ERE.

System action

IMS terminates abnormally with abend 2801, subcode 12.

Operator response

Start IMS again and enter either a cold start command (/NRE CHECKPOINT 0), or enter a restart command that does not conflict with the last online change type.

The following table shows the types of IMS restarts that are permitted for an IMS that was down during online change, with the online change type that was performed while the IMS was down:
