2.9 Rollback to RTR Version 2

To restore the RTR Version 2 environment if RTR Version 3 does not work with your applications as expected, use the following procedure:

1.In the RTR Version 3 environment, stop all clients so that no new transactions can be initiated.

2.Monitor the RTR Version 3 journal to check the status of all current transactions. Once all transactions are complete and the journal is empty, you can proceed to the next step.

3.When all transactions are complete, and the journal file is empty, delete the journal, and shut down the entire RTR Version 3 environment as follows:

a.Shut down RTR applications.

b.Shut down RTR Version 3.

$ RTR DISCONNECT SERVER

c.Remove RTR Version 3 by issuing the following command: $ product remove RTR
