Reason:
This message is generated at the beginning of a rollback with enough log records to be defined as a long transaction. For a definition of a long transaction, see the information about the MUF startup option LOG_ROLLBACK_RECORDS in the CA Datacom/DB Database and System Administration Guide.
In the message text, the S following ROLLBACK indicates this message was generated by the start of the rollback.
Regarding the next three variables in the message text, the first xxxxxxxx is the job name, the nnnnn is the run unit number, and the second xxxxxxxx is the Transaction Sequence Number (TSN).
In the message text next, the n in L-n is a number indicating a count of total log records written by the transaction.
The n in IO-n is the count of I/Os this task has generated up to the point when the message was generated.
The identifier at the end of the message text occurs when there are transactions that executed through controlled APIs such as CA Datacom CICS Services.
This message is not generated for a transaction that has been force check-pointed.
