The CA IDMS DLI Transparency load utility populates an existing CA IDMS/DB database with data unloaded from a DL/I database. This section presents:
  • The initial requirements and preparations you need to make
  • A description of the process of loading data with the DLI load utility
  • Sample code
  • A detailed explanation of each step
The CA IDMS DLI Transparency load utility requires:
  • An initialized CA IDMS/DB database and all supporting software necessary to access the database. The supporting software includes usable CA IDMS/DB schema, subschema, and DMCL modules.
  • The CA IDMS DLI Transparency run-time interface. The load utility runs under the control of the CA IDMS DLI Transparency region controller. Also, the back-end processor performs special handling of the DL/I data during the load.
  • A CA IDMS DLI Transparency interface program specification block (IPSB) load module that accurately describes the DL/I hierarchies involved.
  • Unloaded DL/I data in a format compatible with that produced by the IBM DL/I HD unload utility. The load utility accepts data only if it is in this format.
  • A working knowledge of CA IDMS/DB, DL/I, and CA IDMS DLI Transparency. Knowledge of CA IDMS DLI Transparency includes familiarity with the CA IDMS DLI Transparency syntax generator, the IPSB compiler, and the run-time interface.
