(Workflow) Fail over a PN to an RN

When you start an RN, whether agent‑based or agent‑less, you are indirectly shutting down the PN and PN proxy (VM) respectively and disabling backups for that PN.

To fail over a PN to an RN on the HA Appliance:

1.	Log on to the HA Appliance’s onQ Portal.

2.	Start the recovery node or, if the PN has a Build‑on‑Demand RN creation policy, create the on‑demand RN.

If the RN is agent‑less, the Backup Mode switches from Agentless to Recovery Node.

3.	If applicable, restore the Oracle database:

•	Back up and restore Oracle 11g database on Linux

•	Back up and restore Oracle 10g+ database on Windows

4.	Fix the PN’s server.

When you’re ready to fail back to the PN, go to To fail back an agent‑based RN to a PN on the HA Appliance:

To fail over a agent‑less PN to an RN on the DR Appliance:

If you start an agent-less PN’s RN in production mode on the DR Appliance, you must perform the following steps so that the HA Appliance can back up the RN in production mode on the DR Appliance. This procedure enables onQ to back up the RN on the HA Appliance as a standard agent‑based PN.

1.	Start the RN in production mode on the DR Appliance.

2.	RDP to the RN, then, from a browser window, launch the HA Appliance’s onQ Portal.

3.	Click the Protect Me button to install the onQ Monitor service on the RN.

In the Modify a Protected Node page, switch the RN’s Backup Mode from Agentless to Recovery Node, then SAVE the configuration.

When you’re ready to fail back to the PN, go to To fail back an agent‑less RN to a PN on the DR Appliance:
