DFS555A SUBSYSTEM xxxx OASN yyyyyyyyyyyyyyyy STATUS COMMIT|ABORT
Explanation
This addition to message DFS555I is produced by the IMS sync point processing modules. The purpose of this message is to give the operator enough information so that the external subsystem resources can be properly managed. xxxx represents the subsystem name and the y value represents the originating application sequence number (OASN) that is a part of the recovery ID for the thread.
System action
IMS, acting as a commit coordinator, attempts to manage the thread as indicated in this message. If conditions do not allow IMS to do this, the system programmer can do it by using the appropriate external subsystem commands. IMS must be notified when the system programmer has run the appropriate command.
Operator response
Notify the system programmer about this segment appearing in the message.
System programmer response
The inconsistency of the thread status between IMS and the external subsystem must be corrected. The /CHANGE command enables the function to correct the IMS status. The external subsystem should provide similar function for its half of the thread.
