CA IDMS DLI Transparency Back End

The back end consists of the RHDCDLBE module The back end processing is initiated by a BIND RUN-UNIT issued by IDMSDLFE. The back end performs the following functions during initiation of the run unit:

• Loads the appropriate fixed IPSB
• Acquires storage
• Acquires PCB information from the IPSB and then uses the information to build the PCBs

Once the run unit is initiated, the back end performs the following functions for it:

• Issues appropriate CA IDMS/DB calls to service DL/I requests
• Accepts from CA IDMS/DB retrieved data and/or status information
• Sends retrieved data and/or status information to the front end

After the DL/I application program has executed, RHDCDLBE receives a FINISH from either the front end (in batch processing) or IDMSINTC (in CICS processing) and terminates processing.
