Running the CLIST for adding a new member

The process of adding a new data sharing member involves running some of the installation jobs. Before you run the installation jobs, tailor them to your environment by running the installation CLIST.

About this task

The add-member CLIST tailors the following jobs:

  • DSNTIJIN
  • DSNTIJTM
  • DSNTIJMV
  • Start of changeDSNTIJMAEnd of change
  • DSNTIJUZ
  • Start of changeDSNTIJULEnd of change
  • DSNTIJID
  • DSNTIJFT
  • DSNTIJDE
  • DSNTIJGF

Procedure

To tailor the installation jobs for adding a new member:

  1. Invoke the installation CLIST as described in Generating tailored Db2 12 installation, migration, or function level activation jobs.
  2. On installation panel DSNTIPA1, specify the following values: 
    INSTALL TYPE ===> INSTALL
DATA SHARING ===> YES
.
.
INPUT MEMBER NAME  ===> originating member's output PDS member
OUTPUT MEMBER NAME ===> new member's output PDS member

    Start of changeIn the INPUT MEMBER NAME field, specify the same PDS member name that you specified in the OUTPUT MEMBER NAME field when you ran the CLIST to define the first (originating) member of the data sharing group.End of change

  3. On installation panel DSNTIP0A, specify option 2 for adding a member. 
    | DSNTIP0A                      |
|                               |
|  DATA SHARING FUNCTION:       |
|                               |
|  Select one.                  |
|          2 1. Group           |
|            2. Member          |
|            3. Enable          |
  4. On installation panel DSNTIPK, specify a new member name: 
    MEMBER NAME ===> new member name

    Verify that the new member name is unique within the z/OS® Parallel Sysplex®. Installation job DSNTIJMV edits the ssnmMSTR startup procedure with the member name that you specify on panel DSNTIPK.

  5. Complete the installation panels, specifying parameters according to the Db2 subsystem parameters guidelines.
    Recommendation: Rename the tailored SDSNSAMP data set for each member. This data set contains tailored JCL for each member, including jobs that are used for disabling and re-enabling data sharing, if that should ever become necessary. If you do not rename the SDSNSAMP data set, it is overwritten when you install a new member. Rename the data set by choosing a new name for the prefix.NEW.SDSNSAMP data set on installation panel DSNTIPT. For example, use prefix.member_name.SDSNSAMP.
