How to: Remove subsystems from an RTE

Edit online

To remove a subsystem from a particular runtime environment, clear out all the runtime members that are no longer used in your production libraries. This topic explains how to perform this task using PARMGEN.

About this task

To remove subsystems from your runtime environment using PARMGEN, delete the corresponding parameters in the configuration profile, re-run the $PARSE job and clear out the obsolete members.

Procedure

  1. Define the RTE that you want to configure.
    1. Start the installation and PARMGEN by running the command EX 'gbl_target_hilev.TKANCUS' where gbl_target_hilev is the high-level qualifier for the SMP/E target libraries where the products are installed. The Welcome screen is displayed.
    2. Select option 3 (Configuration Workflow) to enter PARMGEN.
    3. Specify the information of the RTE that you want to configure including GBL_USER_JCL, RTE_PLIB_HILEV, and RTE_NAME. PARAMETER GENERATOR (PARMGEN) Workflow - Primary Option Menu is displayed.
  2. Delete the corresponding parameters in the configuration profile. In the following example, Db2 subsystem SS02 is being deleted from the RTE.
    1. From the Workflow - Primary Option Menu, select option 2 (Customize PARMGEN configuration profiles). The Customize PARMGEN Configuration Profile Members panel is displayed.
    2. Select option 1 to edit the RTE profile.
    3. Block delete all the KD2_DB02_* parameters in the RTE profile.
    4. Save the changes and return to the Workflow - Primary Options Menu panel by pressing F3.
  3. Re-create the RTE and jobs.
    1. Select option 3 (Create this RTE’s members and jobs). The Create the Members and Jobs panel (KCIP@PR1) is displayed.
    2. Select option 1 to go over the job profile and then submit the job.
    3. Press F3 to return to the Workflow - Primary Options Menu panel.
  4. Clear out the obsolete members in production user libraries.
    1. Type U on the workflow main panel to enter the Utilities panel.
    2. Select option 29 to see the detailed information of KCIJPW1R job. This composite job empties out the production user libraries and then copies the work libraries to the production libraries.
    3. Type Submit in the command line to submit the job.

Results

The subsystem is removed from the RTE.
