How to Register and Configure Sun Cluster HA for Sun Java System Application Server EE (HADB)

Perform the following steps to complete your configuration.

Steps

1. Become superuser on a cluster member.

2. Register the resource type for Sun Java System Application Server EE (HADB).

   # scrgadm -a -t SUNW.hadb_ma

3. Create the resource group for the Sun Java System Application Server EE (HADB) software.

   This resource group is configured to be mastered by multiple nodes at the same time.

   # scrgadm -a -g resource_group \ -y Maximum_primaries=nodes_in_rg \ -y Desired_primaries=nodes_in_rg \ -h nodelist

   -a

   Specifies that a resource group is to be created.

   -g resource_group

   Specifies the name of the resource group that is to be created.

   -y Maximum_primaries=nodes_in_rg

   Specifies the maximum number of nodes on which the resource can start. You must specify the same number as the value of the Desired_primaries property.

   -y Desired_primaries=nodes_in_rg

   Specifies the desired number of nodes on which the resource can start. You must specify the same number as the value of the Maximum_primaries property.

   -h nodelist

   Specifies a comma-separated subset of cluster nodes to run the Sun Java System Application Server EE (HADB) software. If this option is omitted, all cluster nodes run Sun Java System Application Server EE (HADB). Use the scconf -p | less command to find the node list names.

4. Create a resource for Sun Java System Application Server EE (HADB).

   See Appendix A, Properties for Sun Cluster HA for Sun Java System Application Server EE (Supporting HADB Versions as of 4.4) for a detailed description of the extension properties for this resource type.

   # scrgadm -a -j resource -g resource_group -t SUNW.hadb_ma \ -x HADBM_PASSWORDFILE=path_to_pw_file

   -a

   Specifies that a data service resource is to be created

   -j resource

   Specifies the name of the resource that you are creating

   -g resource_group

   Specifies the name of the resource group to which the resource is to be added

   -t SUNW.hadb_ma

   Specifies the predefined resource type name

   -x HADBM_PASSWORDFILE=path_to_pw_file

   Specifies the full path to the file containing the HADBM administrative password

   For details about the contents of the password file, see the Sun Java System Application Server documentation.

5. Bring the resource group online.

   # scswitch -Z -g resource_group

   -Z

   Enables the resource and its monitor

   -g resource_group

   Specifies the name of the resource group that is to be brought online

6. Verify that the resource group and HADB resource are online.

   # scstat -g # ps -ef

7. To verify that you have correctly installed and configured Sun Cluster HA for HADB, run the following command.

   # hadbm status database_name --nodes

   The output should indicate that the database that you specified is running.

Example 1–1 Creating a SUNW.hadb_ma Resource

This example shows the creation of a SUNW.hadb_ma resource.

In this example the default values for the extension properties are used. The resource has the following characteristics:

• The resource is named hadb-rs.

• The resource is a member of a resource group named hadb-rg.

• The resource is an instance of the SUNW.hadb_ma resource type. The registration of the resource type is not shown in this example.

scrgadm -a -j hadb-rs -g hadb-rg -t SUNW.hadb_ma \
-x HADBM_PASSWORDFILE=/global/disk1/hadbm-pwfile
