Abstract: This invention provides a method of intercepting a call to a database, such as a DB2 SQL call in batch, CICS, and TSO environments, and routing the call to a DB2 subsystem running in another partition (LPAR) such as a Z/OS partition or another Z/OS mainframe and then transmitting the results back to the originating program. A call is intercepted and redirected to a database in the second LPAR or mainframe. This processing is done transparently to the calling program and transparently to DB2. This allows the administrator to configure the application programming and the DB2 subsystems into separate LPARs or machines.
