Oracle Solaris Cluster software supports the following methods of data replication between clusters or within a cluster:
Replication Between Clusters – For disaster recovery, you can use host-based or storage-based replication to perform data replication between clusters. Generally, you would choose either host-based replication or storage-based replication, rather than a combination of the two. You can manage both types of replication with Oracle Solaris Cluster Geographic Edition software.
Host-Based Replication
Availability Suite feature of Oracle Solaris.
If you want to use host-based replication without Oracle Solaris Cluster Geographic Edition software, see the instructions in Appendix A, Example, Configuring Host-Based Data Replication With Sun StorageTek Availability Suite Software.
Storage-Based Replication
EMC Symmetrix Remote Data Facility (SRDF), through the Oracle Solaris Cluster Geographic Edition.
Oracle ZFS Storage Appliance. For more information, see Data Replication in Oracle Solaris Cluster Geographic Edition Overview .
If you want to use storage-based replication without Oracle Solaris Cluster Geographic Edition software, see the documentation for your replication software.
Replication Within a Cluster – This method is used as a replacement for host-based mirroring.
Storage-Based Replication
EMC Symmetrix Remote Data Facility (SRDF)
Application-Based Replication – Oracle Data Guard is an example of application-based replication software. This type of software is used only for disaster recovery to replicate a single-instance or RAC database. For more information, see the Oracle Solaris Cluster Geographic Edition Data Replication Guide for Oracle Data Guard .
