Oracle E-Business 12.2 support on Oracle Solaris Cluster

We are very pleased to announce that Oracle Solaris Cluster 4.3 SRU 3 on Oracle Solaris 11 introduces support for Oracle E-Business Suite 12.2.

In particular, starting with Oracle E-Business Suite 12.2.4, Oracle Applications DBA (AD) and Oracle E-Business Suite Technology Stack (TXK) Delta 6, Oracle E-Business Suite 12.2 can now be managed by Oracle Solaris Cluster 4.3 SRU 3.

One advantage of deploying Oracle E-Business Suite 12.2 with Oracle Solaris Cluster is the ability to install the Primary Application Tier and subsequent WebLogic Administration Server on a logical host. 

What this means is that, if the physical node hosting the Primary Application Tier and subsequent WebLogic Administration Server fails, then Oracle Solaris Cluster will fail over the Primary Application Tier to another node.

Oracle Solaris Cluster will detect a node failure within seconds and will automatically fail over the logical host to another node where the Primary Application Tier services are automatically started again. Typically, the WebLogic Administration Server is available again within 2-3 minutes after a node failure. Without Oracle Solaris Cluster providing high availability for Oracle E-Business Suite 12.2, you will need to recover the Primary Application Tier and WebLogic Administration Server from a reliable backup.

Please note that if the physical node hosting the Primary Application Tier and subsequent WebLogic Administration Server fails, then patching would not be possible until the WebLogic Administration Server is available again.

The following diagram shows a typical Oracle E-Business 12.2 deployment on Oracle Solaris Cluster 4.3 with Oracle Solaris 11, using Oracle Solaris Zone Clusters.


This deployment example is based on the information available in the “Deployment Option with Single Web Entry Point and Multiple Managed Servers” section of the My Oracle Support (MOS) note, Using Load-Balancers with Oracle E-Business Suite Release 12.2 (Doc ID 1375686.1), with the modification that the Admin Server and its Node Manager are running on the Web Entry Point server.

It is important to note that the Primary Applications Tier and subsequent WebLogic Administration Server have been installed on the logical host primary-lh to enable Oracle Solaris Cluster, in the event of a node failure to fail over the Primary Application Tier services to another node where those services are automatically started again.

Oracle Solaris Cluster Manager: Setting Up Geo Disaster Recovery Orchestration

Oracle Solaris Cluster Manager (Cluster Manager) provides a way to set up and administer disaster recovery (DR) orchestration starting in Oracle Solaris Cluster 4.3. Prior to this version, DR orchestration could be administered only by using the command line interface (CLI). The Cluster Manager browser interface makes it easier by providing a user-friendly way of doing it, with either clicks or by typing in the user-defined fields, eliminating the need to memorize the commands and the sub-commands. Providing inline and online help, Cluster Manager also eliminates potential errors by doing appropriate checks.

Prerequisites for DR Orchestration to Be Usable Under Oracle Solaris Cluster Manager 4.3

  • Geographic Edition software is installed.
    # pkg info ha-cluster/group-package/ha-cluster-geo-full

  • Geographic Edition infrastructure is enabled and the Geographic Edition resource groups and resources are running.
    # /usr/cluster/bin/geoadm show
    # /usr/cluster/bin/clresourcegroup status geo-clusterstate geo-infrastructure
    # /usr/cluster/bin/clresource status -g geo-clusterstate,geo-infrastructure

Access the DR Orchestration

In version 4.3, the DR orchestration feature is accessed via the Sites folder in the navigation pane.

Access Sites Details

The site details can be accessed in one of the following ways:

  • Click the site name in the tree under Sites folder in the navigation pane.
  • Click the Sites folder. Then, click the site name in the Sites table in the main panel.

Access Multigroup Details

Browse to the site details page as mentioned above, then click the multigroup name in the Multigroups table.

Access the Details of a Protection Group In a Multigroup

Browse to the Multigroup details page as mentioned above, then click the protection group name in the Protection Groups table.

  • Click the Sites folder. Click the Create button in the Sites table. A wizard will pop up.
  • In the Initial Setup step, enter the Site Name. The role of the current cluster is controller by default. Click the Add Cluster button to add more clusters. Enter the name of the cluster in the table below the button and the role of the cluster. To skip the next step and use the default site properties, check the checkbox.
    Note: In version 4.3, the cluster to be added to the current cluster must have the same password for root user as that of the current cluster.


  • In the Site Properties step, enter the different site property fields.


  • In the Review step, review the already entered values and click Finish.

Creating a Multigroup

  • Browse to the Site details page as mentioned earlier.
  • Click the Create button in the Multigroups table.

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.
