This procedure describes how to use the scrgadm command to register and configure Sun Cluster HA for Sun Java System Application Server EE (HADB) 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 as of 4.4), which is SUNW.hadb_ma
The names of the cluster nodes that can master the data service
The sections that follow contain instructions for registering and configuring Sun Cluster HA for Sun Java System Application Server EE (HADB) resources. For information about the extension properties, see Appendix A, Properties for Sun Cluster HA for Sun Java System Application Server EE (Supporting HADB Versions as of 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 |
Identifies the extension property that you are setting
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.
Perform the following steps to complete your configuration.
Become superuser on a cluster member.
Register the resource type for Sun Java System Application Server EE (HADB).
# scrgadm -a -t SUNW.hadb_ma |
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 |
Specifies that a resource group is to be created.
Specifies the name of the resource group that is to be created.
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.
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.
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.
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 |
Specifies that a data service resource is to be created
Specifies the name of the resource that you are creating
Specifies the name of the resource group to which the resource is to be added
Specifies the predefined resource type name
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.
Bring the resource group online.
# scswitch -Z -g resource_group |
Enables the resource and its monitor
Specifies the name of the resource group that is to be brought online
Verify that the resource group and HADB resource are online.
# scstat -g # ps -ef |
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.
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 |
