CICS VSAM Transparency for z/OS, Version 1.2


Automated mapping job 2

The batch jobs to create the DDMs have the same job name and are therefore serialized. The job steps are as follows:
Step number Step name Function
1 SQ000000 Extracts the DDM mapping data produced by step 7 in automated mapping job 1.
2 PRECOMP Pre-compiles the assembler source using the DB2® DSNHPC program and creates the DB2 DBRM.
3 PRECOMP Splits the assembler produced by step 2 into multiple CSECTS.
4 ASMB001 Assembles the CSECT for the runtime control blocks.
5 ASMB002 Assembles the CSECT for SQL forward processing.
6 ASMB003 Assembles the CSECT for SQL backward processing.
7 LKED Link-edits the CSECTs from the preceding assembly steps.
8 BIND Binds the DBRM from step 2 into a DB2 package, and binds the application plan for the DDM.
The number of assembly steps is a factor of the value you specify for the number of concurrent threads parameter, which is explained in Specifying mandatory defaults panel 1. If you specify a value of 5, there will be eleven assembly steps.

Step 2 always ends with a return code of 04. Step 7 also might end with a return code of 04, but this is dependent on z/OS® system defaults. All of the other steps should produce return code 00.
