This section helps you to adapt the configuration of your Oracle Solaris Cluster software for the installation of Geographic Edition software. This section also helps you to plan the installation of your data replication software.
Geographic Edition software must be installed on a cluster that is running the Oracle Solaris operating system and the Oracle Solaris Cluster software. You can install Geographic Edition software at the same time that you install Oracle Solaris Cluster software or at any time afterwards. The Geographic Edition software configuration is identical to the Oracle Solaris Cluster software configuration.
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:
StorageTek Availability Suite software.
Hitachi TrueCopy and Universal Replicator software.
EMC Symmetrix Remote Data Facility software.
Oracle Data Guard software.
Geographic Edition script-based plug-ins.
The StorageTek Availability Suite 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.
The Hitachi TrueCopy and Universal Replicator and EMC Symmetrix Remote Data Facility replication use a storage-based method. These methods use replication that is built into the storage hardware. If you use Hitachi TrueCopy and Universal Replicator RAID Manager 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 Database and Oracle Real Application Clusters 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.
