A unit of recovery also known as a Logical Unit of Work (LUW) is a sequence of operations within a unit of work and includes the data and control information needed to enable CA Datacom/DB to back out or reapply all of an application's changes to recoverable resources since the last commit point. A unit of recovery is initiated when a unit of work starts or by the termination of a previous unit of recovery. A unit of recovery is terminated by a commit or rollback operation or the termination of a unit of work. The commit or rollback operation affects only the results of SQL statements and CA Datacom/DB commands executed within a single unit of recovery.
