Distributed transaction resources

Unlike all other resources in a cold start, CICS® preserves any information (units of work) about distributed transactions.

This action has no effect on units of work that relate only to the local CICS; it applies only to distributed units of work. The CICS recovery manager deals with these preserved units of work when resynchronization with the partner system takes place, just as in a warm or emergency restart.

This action is effective only if both the system log stream and the global catalog from the previous run of CICS are available at restart.

For information about recovery of distributed units of work, see Troubleshooting intersystem problems.
