CICS units of work (UOWs)

CICS® UOWs and DBCTL units of recovery are more or less synonymous, except that from CICS’s point of view, a UOW begins at the beginning of a task, and a unit of recovery begins when that task issues its first DL/I request. For simplicity, in the rest of this book, we use the CICS term UOW to refer to both. The IMS publications use the term unit of recovery.
