CA IDMS DLI Transparency Index Maintenance

CA IDMS DLI Transparency creates and updates DL/I index entries for the index relationships defined in the CA IDMS/DB database. In other words, when a source record is inserted, replaced, or deleted in a CA IDMS/DB index relationship, CA IDMS DLI Transparency makes sure that the index relationship's requirements can be met for the insert, replace, or delete call.

You should not input to the load utility any DL/I index entries that would be created by CA IDMS DLI Transparency's index maintenance routines. For example, assume that you have a DL/I index database that is populated whenever a particular root segment is inserted into an associated HDAM database. Since loading of the HDAM database will also populate the index database, there is no need to load the entries in the DL/I index database into the CA IDMS/DB index relationships. CA IDMS DLI Transparency will do this for you.

You can use index suppression exits or null value criteria specifications to support DL/I sparse indexing during the load process. See Index Suppression Exit Support for a discussion of index suppression exits.
