## 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 cluster name to the 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 Availability Suite, EMC Symmetrix Remote Data Facility or Sun ZFS Storage Appliance 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. | See Creating and Modifying a Partnership.
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 Availability Suite, see Chapter 1, Replicating Data With the Availability Suite Feature of Oracle Solaris, in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Oracle Solaris Availability Suite. 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. For information about replicating data by using Sun ZFS Storage Appliance, see Chapter 1, Configuring and Administering Sun ZFS Storage Appliance Protection Groups, in Oracle Solaris Cluster Geographic Edition Remote Replication Guide for Sun ZFS Storage Appliance.
Create protection groups. | Create a protection group. See one of the following data replication guides: How to Create and Configure an Availability Suite Protection Group in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Oracle Solaris Availability Suite How to Create and Configure an SRDF Protection Group in Oracle Solaris Cluster Geographic Edition Data Replication Guide for EMC Symmetrix Remote Data Facility How to Create and Configure a Sun ZFS Storage Appliance Protection Group in Oracle Solaris Cluster Geographic Edition Remote Replication Guide for Sun ZFS Storage Appliance Add data replication device groups. See one of the following data replication guides: How to Add a Data Replication Device Group to an Availability Suite Protection Group in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Oracle Solaris Availability Suite 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 Chapter 1, Configuring and Administering Sun ZFS Storage Appliance Protection Groups, in Oracle Solaris Cluster Geographic Edition Remote Replication Guide for Sun ZFS Storage Appliance Add application resource groups to the protection group. See one of the following data replication guides: How to Add an Application Resource Group to an Availability Suite Protection Group in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Oracle Solaris Availability Suite How to Add an Application Resource Group to an SRDF Protection Group in Oracle Solaris Cluster Geographic Edition Data Replication Guide for EMC Symmetrix Remote Data Facility How to Add an Application Resource Group to a Sun ZFS Storage Appliance Protection Group in Oracle Solaris Cluster Geographic Edition Remote Replication Guide for Sun ZFS Storage Appliance Create a protection group that does not require data replication. 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 an Availability Suite Protection Group in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Oracle Solaris Availability Suite How to Activate an SRDF Protection Group in Oracle Solaris Cluster Geographic Edition Data Replication Guide for EMC Symmetrix Remote Data Facility How to Activate a Sun ZFS Storage Appliance Protection Group in Oracle Solaris Cluster Geographic Edition Remote Replication Guide for Sun ZFS Storage Appliance
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 Availability Suite Data Replication, in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Oracle Solaris Availability Suite Chapter 3, Migrating Services That Use SRDF Data Replication, in Oracle Solaris Cluster Geographic Edition Data Replication Guide for EMC Symmetrix Remote Data Facility Migrating Services That Use Sun ZFS Storage Appliance Remote Replication With a Switchover in Oracle Solaris Cluster Geographic Edition Remote Replication Guide for Sun ZFS Storage Appliance 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 an Availability Suite Protection Group From Primary to Secondary in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Oracle Solaris Availability Suite 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 How to Switch Over Sun ZFS Storage Appliance Remote Replication From the Primary Cluster to the Secondary Cluster in Oracle Solaris Cluster Geographic Edition Remote Replication Guide for Sun ZFS Storage Appliance Note - You cannot perform personality swaps if you are running EMC Symmetrix Remote Data Facility/Asynchronous data replication.
Take over services from primary to secondary during a disaster. | See one of the following data replication guides: How to Force Immediate Takeover of Availability Suite Services by a Secondary Cluster in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Oracle Solaris Availability Suite How to Force Immediate Takeover of SRDF Services by a Secondary Cluster in Oracle Solaris Cluster Geographic Edition Data Replication Guide for EMC Symmetrix Remote Data Facility How to Force Immediate Takeover of Sun ZFS Storage Appliance Services by a Secondary Cluster in Oracle Solaris Cluster Geographic Edition Remote Replication Guide for Sun ZFS Storage Appliance
Recover from a takeover. | Data recovery and error repair outside of the Geographic Edition infrastructure. See the Availability Suite, EMC Symmetrix Remote Data Facility or Sun ZFS Storage Appliance documentation. Resynchronize the partner clusters.
