Registering and Configuring Sun Cluster HA for Sun Java System Application Server EE (HADB)

This procedure describes how to use the scrgadm command to register and configure the Sun Cluster HA for Sun Java System Application Server EE (HADB) data service as a resource mastered on multiple nodes at one time.

See Tools for Data Service Resource Administration in Sun Cluster Data Services Planning and Administration Guide for Solaris OS for details about additional options that enable you to register and configure the data service.

To perform this procedure, you need the following information about your configuration.

• The name of the resource type for Sun Cluster HA for Sun Java System Application Server EE (supporting HADB versions before 4.4), which is SUNW.hadb

• The names of the cluster nodes that can master the data service

Setting Extension Properties for Sun Cluster HA for Sun Java System Application Server EE (HADB)

The sections that follow contain instructions for registering and configuring resources for Sun Cluster HA for Sun Java System Application Server EE (HADB). For information about the extension properties, see Appendix B, Properties for Sun Cluster HA for Sun Java System Application Server EE (HADB Versions Before 4.4). The Tunable entry indicates when you can update a property.

See Appendix A, Standard Properties, in Sun Cluster Data Services Planning and Administration Guide for Solaris OS for details about all of the Sun Cluster properties.

To set an extension property of a resource, include the following option in the scrgadm(1M) command that creates or modifies the resource:

-x property=value 

-x property

Identifies the extension property that you are setting

value

Specifies the value to which you are setting the extension property

You can also use the procedures in Chapter 2, Administering Data Service Resources, in Sun Cluster Data Services Planning and Administration Guide for Solaris OS to configure resources after the resources are created.

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 the Sun Java System Application Server EE (HADB).

   # scrgadm -a -t SUNW.hadb

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

   # 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 Sun Java System Application Server EE (HADB). 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), either with or without auto-recovery.

   • If you do not require the auto-recovery feature, execute the following command.

     # scrgadm -a -j resource -g resource_group -t SUNW.hadb \ -x Confdir_list=config_directory_list \ -x HADB_ROOT=install_directory \ -x DB_name=database_name

     -a

     Specifies that a data service resource is to be created

     -j resource

     Specifies that the resource you are creating is named resource

     -g resource_group

     Specifies that the resource is to be added to the resource group named resource_group

     -t SUNW.hadb

     Specifies the predefined resource type name

     -x Confdir_list=config_directory_list

     Specifies the path to the configuration directory

     -x HADB_ROOT=install_directory

     Specifies the installation directory

     -x DB_name=database_name

     Specifies the name of the HADB database

   • If you do want to use the auto-recovery feature, execute the following command.

     # scrgadm -a -j resource -g resource_group -t SUNW.hadb \ -x Confdir_list=config_directory_list \ -x HADB_ROOT=install_directory \ -x DB_name=database_name \ -x Auto_recovery=TRUE \ -x Auto_recovery_command=command \ -x DB_password_file=password_file

     -x Auto_recovery=TRUE

     Specifies that you are using the auto-recovery feature.

     -x Auto_recovery_command=command

     Specifies the command to execute after the database recovery. This extension property is optional, regardless of the value of the Auto_recovery property.

     -x DB_password_file=password_file

     Specifies the file from which HADB reads the database password. See the Sun Java System Application Server documentation for the format and content of the password file.

     ---

     Note –

     The auto-recovery command and the database password file must both exist in the local file system on each node.

     ---

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 application resource group that is being enabled

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 Sun Java System Application Server EE (HADB), run the following command.

   # hadbm status database_name --nodes

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

Example 2–1 Creating a SUNW.hadb Resource With Auto-recovery

This example shows the creation of a SUNW.hadb resource with auto-recovery.

In this example 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 resource type. The registration of the resource type is not shown in this example.

• The configuration directory is located at /etc/opt/SUNWhadb/dbdef/hadb.

• The installation directory is located at /opt/SUNWappserver7/SUNWhadb/4.

• The HADB database instance associated with this resource is named hadb.

• Auto-recovery is on.

• The full path to the command to execute after auto-recovery is /usr/local/etc/create-session-store.

• The HADB password file is /usr/local/etc/hadb-password-file.

scrgadm -a -j hadb-rs -g hadb-rg -t SUNW.hadb \
-x Confdir_list=/etc/opt/SUNWhadb/dbdef/hadb  \
-x HADB_ROOT=/opt/SUNWappserver7/SUNWhadb/4 \
-x DB_name=hadb \
-x Auto_recovery=true \
-x Auto_recovery_command=/usr/local/etc/create-session-store \
-x DB_password_file=/usr/local/etc/hadb-password-file
