IBM Information Management System 14 details

Easier application deployment and management

Change database schemas using standard data definition language. Load application control blocks from the IMS™ Catalog, eliminating DBDGEN, PSBGEN, and ACBGEN. Record information about how Open Database Manager processes database access requests. Users of extended architecture global transactions using IMS resource adapter can locate IMS and IMS Connect on separate LPARs. Refresh PWFI or WFI programs in dependent regions without the need to recycle the region.

Support for growing transaction and data volumes

Private storage required for open data sets for OSAM databases is reduced. Single IMS OTMA TPIPEs now support multiple active RESUME TPIPE requests, improving failover protection and increasing throughput. Abends previously associated with exhausted 31-bit storage for APPC clients are reduced by queueing support for 64-bit storage, which can also be exploited for IMS high-speed utilities.

Greater agility through dynamic change

Make dynamic changes, which increases IMS availability, to the IMS Connect configuration, MSC resources, and Fast Path DEDBs.

Improved integration of IMS and Db2® for z/OS

IMS and Db2® for z/OS® integration is more robust with the addition of a new user exit that resolves in-doubt threads and reduces the time that Db2 holds locks. New subsystem types for ESAF users help distinguish IBM® MQ and WebSphere® Optimized Local Adapter (WOLA) subsystems from Db2 for z/OS.
