The following configuration considerations affect the installation and configuration of HA for Oracle GoldenGate.
In failover configurations, the binaries of the Oracle GoldenGate software can reside on local storage. The configuration data and the trail files must reside on shared storage.
See Configuration Guidelines for Oracle Solaris Cluster Data Services in Oracle Solaris Cluster Data Services Planning and Administration Guide . This section details the advantages and disadvantages of placing the Oracle GoldenGate binaries on the local file system or on the cluster file system.
In failover configurations, you need at least one corresponding Oracle GoldenGate instance. The second instance can be configured outside of a cluster, although it is highly recommended to make it highly available as well. If you plan to make the other instance highly available also, you will need to repeat the instructions in this guide.
In multiple master configurations, the complete Oracle GoldenGate software including the configuration data and the trail files can reside in the local storage.
