DFS4551E THE MSC= EXECUTION PARAMETER CANNOT CHANGE WITHOUT A COLD START
Explanation
A warm or emergency restart was attempted after the value of the MSC= execution parameter was changed. The restart failed because a cold start is required to change the value of the MSC= execution parameter.
The value of the MSC= parameter might have been changed explicitly in a startup procedure or, if the MSC= parameter is not specified in a startup procedure, IMS might have changed the effective value of the MSC= execution parameter automatically based on the presence or absence of a DFSCLL3x member for MSC resources in the IMS.SDFSRESL data set.
System action
IMS terminates with abend 0168 and reason code X’1E’.
User response
Either change the value of the MSC= execute parameter to its value at the last cold start of the IMS system, or cold start IMS. The second DFS1929I that is issued to the SYSLOG during restart indicates the incorrect value of the MSC= execute parameter.
