Installing a new data sharing group

Although you can install and immediately enable Db2 data sharing on a new Db2 13 member, you should do so only in low-risk situations. The recommended approach is to migrate to, or install, a Db2 13 member, use it for a while, and then enable data sharing.

Before you begin

Familiarize yourself with the following information:

• Planning for Db2 data sharing
• Strategy for creating a Db2 data sharing group

About this task

If you decide to install and immediately enable data sharing on a new Db2 13 member, that member becomes the originating member of the data sharing group. This member's Db2 catalog is used as the Db2 catalog for the entire data sharing group.

To install a new data sharing group:

1. Run the installation CLIST as described in Generating tailored Db2 13 installation, migration, or function level activation jobs. Then on installation panel DSNTIPA1, specify the following values.

   INSTALL TYPE ===> INSTALL
   DATA SHARING ===> YES

2. On installation panel DSNTIP0A, specify option 1 to indicate the group data sharing function.

   | DSNTIP0A                      |
   |                               |
   |  DATA SHARING FUNCTION:       |
   |                               |
   |  Select one.                  |
   |          1 1. Group           |
   |            2. Member          |
   |            3. Enable          |

3. On installation panel DSNTIPK, specify:

   GROUP NAME   ===> group name
   MEMBER NAME  ===> originating member name

   Verify that the originating member name is unique within the z/OS® Parallel Sysplex®. Installation job DSNTIJMV edits the ssnmMSTR startup procedure with the group name and member name you specify here.

4. Complete the installation panels and specify all of the parameters.
5. Complete the installation of Db2 by following the installation steps in Installing Db2 13.
6. Run the installation verification procedures (IVP).
