2.See the Reliable Transaction Router Installation Guide for information on installing the product and reading release notes.

In a cluster environment, a planned transition from RTR Version 2 to Version 3 could be done as follows:

1.Install RTR Version 3 on a single standalone node.

2.Bring up RTR Version 3 on the standalone node with the RTR application.

3.Verify that the application and RTR Version 3 work as expected. Resolve any problems before proceeding.

4.Stop all transactions and RTR with the following commands:

$ RTR STOP RTR

$ RTR DISCONNECT SERVER $ RTR DUMP JOURNAL

5.Examine the output of the DUMP JOURNAL command to verify that all transactions have been flushed from the journal.

6.Bring down RTR Version 2 on the entire cluster.

7.Install RTR Version 3 on the cluster.

8.Start up RTR Version 3 on each node.

9.Verify that the application is running correctly on each node.

10.Verify that the application is running correctly on the cluster.

11.Verify that the application is running correctly throughout the RTR facility and network environment.

2.1 Cleaning Up the Old Version 2 Environment

Before bringing up the RTR Version 3 environment, you will need to shut down RTR Version 2 on client systems, let the RTR journal file clear, and then bring up RTR Version 3. This should be part of the process you use in your planned migration. See Section 2.6 for more information on checking journal files.
