The CA IDMS DLI Transparency Syntax Generator

What is the CA IDMS DLI Transparency Syntax Generator

The CA IDMS DLI Transparency syntax generator helps to automate the conversion process on the database definition level. It accepts as input control blocks (load modules) for the program specification blocks (PSBs) and database definitions (DBDs). These are used by the DL/I application against the existing DL/I database(s).

The Syntax Generator Produces Source Statements

For output, the syntax generator produces the source statements necessary to create the interface program specification block (IPSB). It also produces source definitions needed to create an appropriate schema, DMCL, and subschema. Collectively, the schema, DMCL, and subschema definitions represent the database definitions for the new CA IDMS/DB database.

After producing the sets of source statements, you can check them and modify them (particularly the DMCL), to address capacity planning and performance and tuning concerns.You can then input the source statements to the CA IDMS/DB compilers and the IPSB compiler, respectively.
