Issue/Introduction

Run HDDL line command in Batch using an Alternate Catalog

Environment

DB2 for Z/OS

Release : R20

Resolution

1. Set your Alternate catalog 

On the main menu turn on and reference the ACM

20.0.06  Database Management Solutions for Db2 for z/OS       yyyy/mm/dd hh:mm
OPTION ===>                                                   SCROLL ===> CSR

DB2 SSID ==> ssid LOCATION ==> LOCAL                   DB2 VERSION: V12R1M500
ACM      ==> ON   ACMID    ==> ACMNEW   SQLID ==> authid1


2. Go to RC/Query and select the object and enter the HDDL line command.

The dataset must have a DCB of FB, LREL 80.
If it does not exist yet, the JCL will create it for you.

The generated JCL looks like this:

The output dataset authid1.MLQ.HDDLOUT will contain the DDL of the objects selected and dependants as requested on the screen.

As this example was run using the "SPUFI Compatible . . . N" setting, it can only be run using BATCH PROCESSOR as it has BATCH PROCESSOR commands in it. If, however "SPUFI Compatible . . . Y" is used before execution of the batch job, the DDL will be generated WITHOUT any BATCH PROCESSOR commands such as .CONNECT so that it can be executed by any SQL processing program like SPUFI or DSNTEP2 for instance.
