Using CA IDMS DLI Transparency Within CA IDMS/DB Programs › Operational Considerations › System Execution

System Execution

The automatic scheduling of an IPSB associated with an application program (as defined in the CA IDMS DLI Transparency program definition table) is performed whenever the application program is linked to, either by the CA IDMS/DB system itself or from another application program.

• If an application program named in the CA IDMS DLI Transparency program definition table (DLPDTAB) is also associated with a CA IDMS/DB task code, then entering that task code in response to an ENTER NEXT TASK CODE message causes automatic scheduling of the IPSB before CA IDMS/DB passes control to the application program.
• The automatic scheduling is done during the linking process (that is, after the program issuing the LINK command gives up control but before the target program receives control) if an application program that is not named in the DLPDTAB links to an application program that is named in the DLPDTAB.

All application programs receiving control from a region controller (following the automatic scheduling) must be set up to receive the scheduled PCBs. This is the same as for CA IDMS DLI Transparency batch, IMS-DC, and IMS-DB.
