## Overview of Geographic Edition Administration Tasks

This section provides a starting point for administering the Geographic Edition software. This section contains the following tasks:

- Prerequisite Administration Tasks

- Geographic Edition Administration Tasks

### Prerequisite Administration Tasks

Before you begin administering the Geographic Edition software, you must identify the Oracle Solaris Cluster installations you need to host protection groups. Then, you need to adjust the Oracle Solaris Cluster configuration and environment to support the formation of partnerships and protection groups with the Geographic Edition software. The following table describes these prerequisite tasks.

Table 2-2 Geographic Edition Prerequisite Tasks

Task | Description
--- | ---
Set the `SC-clustername` to the cluster name you want to use with the Geographic Edition software. | Use the `cluster`(1CL) command. For more information, see How to Enable Geographic Edition Software.
Set up the IP address and host maps for the cluster that is enabled to run Geographic Edition software. | See Chapter 2, Installing Software on Global-Cluster Nodes, in Oracle Solaris Cluster Software Installation Guide.
Install and configure your data replication product. | See the Sun StorageTek Availability Suite, Hitachi TrueCopy and Universal Replicator, or EMC Symmetrix Remote Data Facility documentation. This step is required before you can create protection groups with the `geopg create` command.
Port and configure application configuration and corresponding resource groups on clusters that are candidates for partnership. | You can use the Oracle Solaris Cluster `scsnapshot` tool to facilitate porting of application resource groups. See Creating and Modifying a Partnership for more information.
Enable the common agent container on all nodes of both clusters. | See Enabling the Geographic Edition Software.

### Geographic Edition Administration Tasks

After you have completed the prerequisite administration tasks, you can install, configure, and administer the Geographic Edition software as described in the following table.

Table 2-3 Geographic Edition Administration Tasks

Task | Description and Documentation
--- | ---
Install Geographic Edition software. | See the Oracle Solaris Cluster Geographic Edition Installation Guide.
Set up security between the candidate partner clusters. | Exchange certificates, as described in Configuring Secure Cluster Communication Using Security Certificates. (Optional) Configure a secure logical hostname that uses IP Security Architecture (IPsec), as described in Configuring Secure Cluster Communication Using IPsec.
Enable the Geographic Edition software. | Use the `geoadm start` command. For more information, see Enabling the Geographic Edition Software.
Create partnerships. | See How to Create a Partnership. This procedure includes the following: Modifying the default heartbeat. For more information, see Chapter 6, Administering Heartbeats. Configuring loss of heartbeat notification. For more information, see Configuring Heartbeat-Loss Notification.
Configure data replication. | For information about replicating data by using Sun StorageTek Availability Suite, see Chapter 1, Replicating Data With Sun StorageTek Availability Suite Software, in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Sun StorageTek Availability Suite. For information about replicating data by using Hitachi TrueCopy and Universal Replicator, see Chapter 1, Replicating Data With Hitachi TrueCopy and Universal Replicator Software, in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Hitachi TrueCopy and Universal Replicator. For information about replicating data by using EMC Symmetrix Remote Data Facility, see Chapter 1, Replicating Data With EMC Symmetrix Remote Data Facility Software, in Oracle Solaris Cluster Geographic Edition Data Replication Guide for EMC Symmetrix Remote Data Facility.
Create protection groups. | Create a protection group. See one of the following data replication guides: How to Create and Configure a Sun StorageTek Availability Suite Protection Group in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Sun StorageTek Availability Suite How to Create and Configure a Hitachi TrueCopy or Universal Replicator Protection Group That Does Not Use Oracle Real Application Clusters in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Hitachi TrueCopy and Universal Replicator How to Create and Configure an SRDF Protection Group in Oracle Solaris Cluster Geographic Edition Data Replication Guide for EMC Symmetrix Remote Data Facility Add data replication device groups. See one of the following data replication guides: How to Add a Data Replication Device Group to a Sun StorageTek Availability Suite Protection Group in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Sun StorageTek Availability Suite How to Add a Data Replication Device Group to a Hitachi TrueCopy or Universal Replicator Protection Group in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Hitachi TrueCopy and Universal Replicator How to Add a Data Replication Device Group to an SRDF Protection Group in Oracle Solaris Cluster Geographic Edition Data Replication Guide for EMC Symmetrix Remote Data Facility Add application resource groups to the protection group.

See Creating a Protection Group That Does Not Require Data Replication.
Bring the protection groups online. | See one of the following data replication guides: How to Activate a Sun StorageTek Availability Suite Protection Group in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Sun StorageTek Availability Suite How to Activate a Hitachi TrueCopy or Universal Replicator Protection Group in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Hitachi TrueCopy and Universal Replicator How to Activate an SRDF Protection Group in Oracle Solaris Cluster Geographic Edition Data Replication Guide for EMC Symmetrix Remote Data Facility
Test the configured partnership and protection groups to validate the setup. | Perform a trial switchover or takeover and test some simple failure scenarios. See one of the following data replication guides: Chapter 3, Migrating Services That Use Sun StorageTek Availability Suite Data Replication, in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Sun StorageTek Availability Suite Chapter 3, Migrating Services That Use Hitachi TrueCopy and Universal Replicator Data Replication, in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Hitachi TrueCopy and Universal Replicator Chapter 3, Migrating Services That Use SRDF Data Replication, in Oracle Solaris Cluster Geographic Edition Data Replication Guide for EMC Symmetrix Remote Data Facility Note - You cannot perform personality swaps if you are running EMC Symmetrix Remote Data Facility/Asynchronous data replication.
Migrate services to the partner cluster. | See one of the following data replication guides: How to Switch Over a Sun StorageTek Availability Suite Protection Group From Primary to Secondary in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Sun StorageTek Availability Suite How to Switch Over a Hitachi TrueCopy or Universal Replicator Protection Group From Primary to Secondary in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Hitachi TrueCopy and Universal Replicator How to Switch Over an SRDF Protection Group From Primary to Secondary in Oracle Solaris Cluster Geographic Edition Data Replication Guide for EMC Symmetrix Remote Data Facility Note - You cannot perform personality swaps if you are running EMC Symmetrix Remote Data Facility/Asynchronous data replication.
