A cluster that is using Geographic Edition software with a data replication product is subject to the standard configuration rules of a cluster that is running the data replication product with Oracle Solaris Cluster software. Partner clusters must have compatible software configurations to support data replication between the clusters.
The Geographic Edition product supports the following data replication products:
The Availability Suite feature of the Oracle Solaris OS
EMC Symmetrix Remote Data Facility software.
MySQL software.
Oracle Data Guard software, in configurations that use Oracle Database software.
Oracle ZFS Storage Appliance software from Oracle.
Geographic Edition script-based plug-ins.
The following sections describe the types of replication that the above products provide:
The Availability Suite feature of Oracle Solaris software is a host-based replication method. This method consists of software installed on a host that controls replication from one server to a secondary server.
Oracle ZFS Storage Appliance and EMC Symmetrix Remote Data Facility replication use a storage-based method. This method uses replication that is built into the storage hardware. If you use Oracle ZFS Storage Appliance software or EMC Symmetrix Remote Data Facility software, you must install the software on each node of the cluster.
Oracle Data Guard functionality is part of the Oracle Database software and so does not require you to install additional software onto your system. The Geographic Edition module for Oracle Data Guard can only be used with Oracle databases.
MySQL database software offers a built-in replication protocol. Configuring the Geographic Edition MySQL replication module enables you to control replication between MySQL instances on each site.
The Geographic Edition script-based plug-in enables the user to develop replication modules to integrate additional replication protocols into Geographic Edition. The plug-in provides the interface to register custom replication control scripts with Geographic Edition.
