Special Load IPSBs

The IPSB Load Module

The IPSB load module provides the CA IDMS DLI Transparency run-time interface with a description of the DL/I database hierarchies that are referenced in the PCBs (database views) defined for the DL/I application. The IPSB also defines those logical relationships that involve other DL/I databases. Make sure that these logical relationships are correctly defined so that the load utility can find the logical parent records necessary to populate the logical workfile.

Review the IPSB

Specifically, make sure that the IPSB defines:

Note that logically related databases are defined by way of multiple PCBs within the IPSB. The multiple PCBs are the equivalents of multiple logical DBD descriptions, with full hierarchical definitions, included within the same PSB. Each logically related database is represented by at least one PCB. If the logical relationships do not cross database boundaries, only one PCB that defines the logical relationships is required in the IPSB load module.

In the case of multiple DL/I databases, it is recommended, but not required, that you use one IPSB load module with multiple PCBs.
