IMS and DB2 are Data Base Management Systems that provide application program access to only secure data. Data that is concurrently being changed is not available to other concurrently running programs. This isolation is provided by implementing and enforcing data locking protocols where the order of such locking guarantees the integrity of data access and change. In IMS and DB2 running on IBM's z/OS operating system, this is implemented to provide inter-processor data sharing using IRLM as the global lock manager.
