Oracle GoldenGate is a replication software. In general, you need at least two instances of Oracle GoldenGate for the software to be fully functional.
The corresponding Oracle GoldenGate instance can be configured either as a failover or as a multiple master.
For failover configuration, the following two options are available:
The corresponding Oracle GoldenGate instance can to be configured within the same cluster or in a different cluster. If you plan on using a different cluster for configuring the corresponding Oracle GoldenGate instance, then repeat the configuration steps as described in this document.
If you do not plan on making the corresponding Oracle GoldenGate instance highly available, then just install and configure Oracle GoldenGate on the unclustered server. If you do plan on making the corresponding Oracle GoldenGate instance highly available on a platform other than Oracle Solaris Cluster, then follow the documentation for the other platform.
In a multiple master configuration, you will also have a multiple master configuration for your database. Install and configure the replication for the Oracle GoldenGate instances for every database that you made highly available. You might have to configure replication with Oracle GoldenGate between the databases within this cluster, or just have the databases as replication targets for a different Oracle GoldenGate instance, depending on the Oracle GoldenGate replication topology.
