Multiple instances of the TCBs (RRS, DYx, and RCF, for example) can be created during the life of an IMS session as the workload requires. The initialization of each new TCB produces this message.
System action
After sending this message, the identified component will process any queued work requests.
System programmer response
If IMS fails during or immediately after the initialization process, the absence of this message helps in identifying the component in which the failure occurred.
