Configuring a Data Service for Oracle VM Server for SPARC by Using a Graphical Wizard

In earlier releases of Oracle Solaris Cluster,  you were able to configure a data service (sometimes also referred to as an agent) for Oracle VM Server for SPARC only manually using a command line interface. This was tedious, requiring the administrator to run commands on multiple nodes.

With Oracle Solaris Cluster 4.3 comes a new graphical wizard that simplifies the configuration considerably. The wizard, using a few clicks, makes a guest domain, as a black box entity, highly available.

Introducing the New Cluster Configuration Wizard

Oracle Solaris Cluster users have been using the scinstall command-line interface to configure new clusters in the past. Version 4.3 of the software is introducing a new browser-based wizard that makes this process easier. Users will be able to navigate through a series of panels in a browser to configure a new cluster.

The new cluster configuration wizard in the Oracle Solaris Cluster Manager browser interface has a typical mode and a custom mode. They provide the same degree of customization to the user when configuring a new cluster as the existing interactive scinstall utility, all in a more intuitive interface.

As prerequisites to use this new feature, you will need Oracle Solaris Cluster packages installed on all nodes that are planned to form a new cluster and you need to run the clauth command on all non-control nodes to authenticate the control node, if you haven’t done so previously.

Then you can open a browser and navigate to address “hostname:8998/scm/faces/main”. The “hostname” here stands for the host of the webapp server that Cluster Manager runs on. Note that the host could be the control node (just make sure the Cluster Manager packages are installed on that node) or any machine hosting Cluster Manager that could access the control node. The address will lead you to the login page (shown below). Login as the root role to the control node on this page and you can now start configuring a new cluster.

The panels guide you through the process of configuring a new cluster. You might find the online help pane handy on the right side of the page. At the end of the process, the wizard invokes a script to configure and reboot each node in a sequence automatically. The control node will be the last one in the sequence that is configured and rebooted. When all nodes are rebooted, the new cluster configuration process is completed.

Configuring HA for Oracle WebLogic Server Managed Servers by Using the clsetup Wizard

This post describes the steps to use the clsetup wizard to configure an Oracle WebLogic Server Managed Servers instance as a highly available failover data service with Oracle Solaris Cluster software.

HA Prerequisites

  • The logical host resource to be used by the data service is configured.

  • The administration server instance of Oracle WebLogic Server software is running. This is to avoid the delay during discovery of the managed servers, which might take 10 minutes or longer.

  • The common agent container (cacao) service is running on the nodes on which Oracle WebLogic Server software will be configured.

Application Prerequisites

  • The boot.properties file is in the $DOMAIN_DIR/servers/<server-name>/security folder.

  • The Managed Server to be configured is created.

Points to Note

While using the clsetup wizard:

  • Type a question mark (?) to access the help.

  • Type a left angle bracket (<) or a right angle bracket (>) to move backward or forward, respectively.

  • Each input provided is validated by the wizard.

Procedure

From a command prompt, type clsetup to start the utility. From the clsetup menu, select "Data Services". In the next menu, select “Oracle WebLogic Server”.

The following table is an overview of the steps that the clsetup wizard performs to configure the data service.

#

Step

Remarks

1

Select Oracle WebLogic Server Location

Select "Global Cluster" or "Zone Cluster". If you select “Zone Cluster”, in the next menu select the zone cluster in which to configure the data service.

2

WebLogic Server Configuration

Lists the available types of configuration. Select “Managed Servers”.

3

Verify Prerequisites

Make sure all listed prerequisites are met.

4

Specify Domain Location

Be sure to provide the proper domain location. If you provide the proper domain location and no customized configuration is made in the Oracle WebLogic Server software, the clsetup wizard will auto-discover the parameter values.

5

Specify WebLogic Home Directory

Either select a directory from the discovered values or specify your own home directory by selecting the option “Specify explicitly”.

6

Specify WebLogic Managed Server Start Script

Press “RETURN” to accept the discovered value or type your own value.

7

Specify WebLogic Server Environment File

Press “RETURN” to accept the discovered value or type your own value.

8

Select Configuration Mode for Managed Servers

Select “Failover”.

9

Select Managed Server

Select from the displayed list the Managed Server that you want to configure.

10

Select Logical Hostname for Managed Server <Managed Server Name>

Select the appropriate logicalhost from the list.

11

Specify Monitoring URI

Specify the URI or leave the field blank. To specify multiple monitoring URIs, separate them by commas. If you specify a URI, it will be validated.

12

Configure Highly Available Storage Resources

Select the appropriate storage from the list.

13

Review Panel

Displays the values entered. To edit the information, choose the corresponding number.

14

Summary Panel

Displays the values you entered. [This panel is read only.]

Configuring the HA for Oracle WebLogic Server service by using the clsetup wizard is easy, effective, and ensures proper configuration of properties for resources and resource groups.
