Recovery Manager domain recovery messages

The messages are produced by the Recovery Manager after processing the system log, and they accurately represent the state of the CICS® system workload at the time the cancellation, abend, or termination occurred. When the messages are produced, the Recovery Manager attempts to resolve the UOWs by committing, backing-out, or temporarily suspending completion (shunting) them.

The messages are as follows:-

DFHRM200

 <applid> xx Indoubt UOWs were reconstructed       

After reading the system log, the CICS Recovery Manager found that there was the specified number of UOWs that were shunted indoubt, or were waiting indoubt at the time the system was terminated. Both types have suffered an indoubt failure with their recovery coordinator, for example, another CICS, or DBCTL. They must wait to be reconnected or resynchronized with the coordinator before they can commit or backout the changes made within a particular shunted UOW, that is to complete a syncpoint. Recovery coordinators will be across LU6.2, LU6.1, MRO (XM/IRC/XCF) links, or a product interface through the Resource Manager Interface (RMI) such as DBCTL, IBM® MQ or DB2®.

DFHRM201

<applid> xx backout-failed and commit-failed UOWs were reconstructed

After reading the system log, the CICS Recovery Manager finds a specified number of UOWs shunted while awaiting the availability of a LOCAL recoverable resource that was updated by the task in question. The local resources to CICS are files, RLS files, TD queues, TS Queues, RDO objects and user. There are many reasons why a recoverable resource cannot be committed or backed out, for example, RLS server not available, I/O errors on data sets, coupling facility errors, backout exit failures. As with the message DFHRM200, the UOWs could not complete their syncpoint processing. However, they are not shunted while awaiting resolution of an indoubt failure.

DFHRM202

<applid> xx inflight UOWs were reconstructed

After reading the system log, the CICS Recovery Manager finds a specified number of UOWs in progress. That is, the number of tasks that were executing in the CICS region before the system was terminated abnormally. These tasks are in between syncpoint requests and therefore have to be backed-out (rollbacked) or shunted awaiting resynchronization with an external resource manager such as DBCTL.
