Configure Oracle MaxRep High Availability

You can configure two Oracle MaxRep Replication Engines as a clustered high availability (HA) pair.

Prerequisites

HA Cluster information includes:

IP address or host name
Multicast Group IP address
Ping node IP address

Primary and secondary node information includes:

IP address or host name
Fully qualified domain name

Two Replication Engines make up an HA cluster. One Replication Engine is in Active mode, while the other Replication Engines is in Standby, or Passive mode. Both of the Replication Engines in the cluster use the same multicast group IP address.

After you configure the HA environment, you cannot access the Oracle MaxRep Support User Interface from the cluster IP address or host name. Instead, update the individual Replication Engine host name.

Important: Configuring HA in the Oracle MaxRep for SAN environment is a one‑way process. If you change your mind and want to configure your system as non‑high availability, then you must start the configuration process from the beginning, which might also include reinstalling the Replication Engine image.

Log in to the Support User Interface page on the control service Replication Engine.
Result:
The Dashboard page displays.
Select Management Tasks > Configure MaxRep HA.
Select the Primary Node Replication Engine.
Enter the Domain Name of Primary Node.
Select the Seondary Node Replication Engine.
Enter the Domain Name of Secondary Node.
Enter the remaining HA configuration information:
- Multicast Group IP Address
- Ping Node
- Cluster IP Address
- Appliance HA Cluster Name
To save your changes, click Save HA Details.

When you save your changes, the system displays the Task Status page. You can monitor the task progress and, in some cases, cancel the change from this page.
