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.

Announcing Oracle Solaris Custer 3.3 3/13 !

We are pleased to announce Oracle Solaris Cluster 3.3 3/13 today! This  release is an important milestone for our Oracle Solaris 10 customers as it delivers to them the same advanced Oracle Solaris Cluster 4.1 features. 



As more and more customers deploy Oracle Solaris Cluster on Oracle Solaris 11, some enterprises still have various factors to consider before moving onto a different OS version. However, their needs for the latest and greatest HA technologies should not be compromised. Oracle Solaris Cluster 3.3 3/13 is bridging that gap. Customers will also become familiar with Oracle Solaris Cluster 4.x features when they are ready to move on to Oracle Solaris 11.


Let's look at some of the highlights in this release:


Best for Oracle Environments


·       Disaster recovery with ZFS Storage Appliance replication 


·      Increased availability for Oracle applications such as Oracle Web-Tier for Fusion Middleware and PeopleSoft Job Scheduler with new agents


·       Multi-cluster dependencies management for Oracle database 11g through Oracle External Proxy


·       Automated setup and configuration for PeopleSoft and WebLogic Server through configuration wizards 


Built for Cloud Infrastructure


·       Faster deployment of virtualized HA configurations through Zone cluster configuration wizard


·       Multi-level, labeled security in Zone clusters using Oracle Solaris Trusted Extensions


Best Availability for Enterprise Solutions

·      Faster failure detection and failfast for storage devices, reducing
storage failure detection time and client time out from minutes to
seconds)


·       Improved per node dependencies management, decreasing client timeout to seconds


·       Increased availability for enterprise applications such as new application versions for SAP NetWeaver


Oracle Solaris Cluster tested all applications that we support together with  Oracle Sun systems, Oracle and 3rd party storage and networking technologies. Out-of-the-box and in a few steps, your application is made ready to take your business-critical missions and run in local, campus, metropolitan, and worldwide clusters in physical and virtual environments.

Stay in sync with a changing SAP world

Over the years, the SAP kernel changed a lot. Finally, the architecture of our SAP agents had reached its limits. It was clearly time for a rewrite of the SAP agent. To accommodate the changes in the SAP kernel, we created the new HA for NetWeaver agent. We also took this chance to support central instance and traditional HA deployments within this one agent. This integration reduces the resource complexity.


Most recently, the SAP kernel 7.20_EXT SAP introduced the ability to integrate HA frameworks. Of course, we did not miss the opportunity to integrate our new SAP NetWeaver agent with this functionality. So, with the new HA for NetWeaver agent, it is now possible to use the SAP command and the SAP Management console to manage SAP instances under cluster control, without having root access. This will improve the ease of use for SAP in an Oracle Solaris Cluster environment. We made these functionalities available on Oracle Solaris 11 software starting with Oracle Solaris Cluster 4.0 SRU 4.


One of the larger cities in Europe made the change with their SAP system from Oracle Solaris 10 to Oracle Solaris 11 as soon as the HA for NetWeaver agent was available. They reduced their system administration costs because of the benefits of Oracle Solaris 11 and Oracle Solaris Cluster 4.0. Information about this customer use case is available at:
http://www.oracle.com/us/corporate/customers/customersearch/city-of-nuremberg-1-solaris-ss-1912239.html


We look forward to your feedback and inputs !
