You must be an experienced Oracle Solaris Cluster administrator to administer the Geographic Edition framework.
This section describes the following Oracle Solaris Cluster administration topics that you need to understand before you administer the Geographic Edition framework:
You use either Oracle Solaris Cluster commands or the Oracle Solaris Cluster Manager browser interface to create failover and scalable resource groups.
For more information about administering resources and resource groups in Oracle Solaris Cluster software, see the Oracle Solaris Cluster 4.3 Data Services Planning and Administration Guide.
This section lists the requirements for legal characters for the names and values of Geographic Edition entities.
This appendix contains the following sections:
Geographic Edition entity names consist of the following:
Cluster names, which must follow the naming requirements for host names
Protection group names
Custom heartbeat names
All names must comply with the following rules:
Must start with a letter
Must not exceed 255 characters
Can contain the following:
Upper and lowercase letters
Dashes (-), except as the last character of a host name or cluster name
Underscores (_), except in a host name or cluster name
For more information about host name requirements, see RFC 1123 at http://www.rfcs.org/.
The Geographic Edition entity values fall into two categories: property values and description values. Both types of values share the following rules:
Values must be in ASCII
The maximum length of a value is 4 megabytes minus 1, that is, 4,194,303 bytes
Values cannot contain a newline or a semicolon
This section describes how to administer role-based access control (RBAC) rights in the Geographic Edition framework. For information about rights for the Geographic Edition framework, see Planning Security in Oracle Solaris Cluster 4.3 Geographic Edition Installation and Configuration Guide.
When you grant authorization to users other than the root role, you must do so on all nodes of both partner clusters. Otherwise, some operations that have a global scope might fail due to insufficient user rights on one or more nodes in the partnership.
To modify the rights for a user, you must be logged in as the root role or assume a role that is assigned the System Administrator rights profile.
For example, you can assign the Geo Management rights profile to the user admin as follows:
# usermod -P "Geo Management" admin # profiles admin Geo Management Basic Solaris User #
For more information about how to modify the rights properties for a user, refer to Chapter 2, Oracle Solaris Cluster and User Rights in Oracle Solaris Cluster 4.3 System Administration Guide.
The logical hostname is a special high-availability (HA) resource. The geoadm start command configures the logical hostname that corresponds to the cluster name. You must set up the IP address and host maps for the logical hostname before you run this command.
For more information about using the geoadm start command, see Enabling and Disabling the Geographic Edition Framework.
All naming services that are being used
The local /etc/inet/hosts file on each cluster node, after you install the Oracle Solaris OS software
For more information about configuring the IP address and host maps during the installation of Oracle Solaris Cluster software, refer to Chapter 2, Installing Software on Global-Cluster Nodes in Oracle Solaris Cluster 4.3 Software Installation Guide.
A device group is a hardware resource that is managed by the Oracle Solaris Cluster software. A device group is a type of global device that is used by the Oracle Solaris Cluster software to register device resources, such as disks. A device group can include the device resources of disks and Solaris Volume Manager disk sets.
For information about configuring device groups in Oracle Solaris Cluster software, refer to Chapter 5, Administering Global Devices, Disk-Path Monitoring, and Cluster File Systems in Oracle Solaris Cluster 4.3 System Administration Guide.
The Geographic Edition framework configures Oracle Solaris Cluster device groups to include replication.
For more information about configuring data replication in the Geographic Edition framework, see the Geographic Edition documentation for the data replication product you use.
The following table lists administration tasks for your Geographic Edition configuration.
