A method includes providing an application accelerator to an IMS region controller, which is coupled to an IMS data language interpreter (DL/I) interface. The IMS DL/I interface provides standard data access paths to a user application launched in an IMS environment. The application accelerator is configured to make alternate data access paths available to the user application in addition to the standard data access paths provided by the IMS environment. The method further includes intercepting an IMS DL/I call made by the user application and determining whether the intercepted call should be processed by the IMS DL/I interface or by an I/O engine of the application accelerator.

Systems, methods and computer readable medium for migrating Information Management System (IMS) Full-Function databases to IMS High Availability Large Databases (HALDBs) are described. Full Function database conversion operations in accordance with this disclosure assign a unique identifier to each segment having a physically paired logically related child segment. These unique identifiers may then be used during HALDB load operations to identify a segment's physically paired logically related segment. Use of the disclosed unique identifiers permit Full Function database conversion operations to avoid the input-output (I/O) and compare operations needed by prior art unload techniques to completely identify physically paired logically related segments.
