How to setting up TSA Peer Domain Manually

Creating the TSA peer domain manually

Follow the steps below to create TSA manually your machine:

Example:

Host1: coralaixtest16
Host2: coralaixtest12

From Host1 execute the following commands:

Step 1: preprpnode coralaixtest12 coralaixtest16

Step 2: mkrpdomain db2domain coralaixtest12 coralaixtest16

Step 3: export CT_MANAGEMENT_SCOPE=2

Step 4: startrpdomain db2domain

Output:
-bash-3.2# lsrpdomain
Name OpState RSCTActiveVersion MixedVersions TSPort GSPort
db2domain Online 2.5.3.2 No 12347 12348

-bash-3.2# lsrpnode
Name OpState RSCTVersion
coralaixtest16 Online 2.5.3.2
coralaixtest12 Online 2.5.3.2

Removing the TSA peer domain

1. Check if the peer domain exists on the machine by executing the following command:

-bash-3.2# lsrpdomain

Name OpState RSCTActiveVersion MixedVersions TSPort GSPort
db2domain Online 2.5.3.2 No 12347 12348

If nothing is listed, the host is TSA clean. Only one TSA peer domain can be active (online) at any given time, and any operation (stopping/removing/adding a node) will only affect this online domain.

2. List all the nodes in this active peer domain by running the lsrpnode command. The output of this command should be similar to the following:

Name OpState RSCTVersion
instaixtest5 Offline 2.5.2.2
instaixtest8 Online 2.5.2.2
instaixtest7 Online 2.5.2.2

3. Remove the membership from online peer domain. This step can be accomplished in two ways:

Use this option if you want to remove one or more nodes from your peer domain.

a. Identify one of the online nodes as your target node.
b. Run the stoprpnode <target_node_name> command.
c. Run the rmrpnode <target_node_name> command.
d. Repeat these steps for any other node that you would like to remove from your peer domain.
e. Use this option if you want to remove the entire peer domain, including all nodes.

a. Run the rmrpdomain [PD_name] command.

Example:

rmrpdomain <domainname>

If you want remove the TSA peer domain forcefully, execute the following command:

rmrpdomain –f <domainname>

4. Confirm if the peer domain has been removed or trimmed appropriately.
a. To confirm the peer domain has been removed, run the lsrpdomain command.
b. To confirm the peer domain has been trimmed, run the lsrpnode command.

The TSA peer domain should not be listed in the output.
