Planning the Oracle Solaris Cluster HA for WebLogic Server Installation and Configuration

This section contains the information you need to plan your Oracle Solaris Cluster HA for WebLogic Server installation and configuration.

Configuration Restrictions


Caution

Caution - Your data service configuration might not be supported if you do not observe these restrictions.


This section provides a list of software and hardware configuration restrictions that apply to Oracle Solaris Cluster HA for WebLogic Server. Use the restrictions in this section to plan the installation and configuration of Oracle Solaris Cluster HA for WebLogic Server.

For restrictions that apply to all data services, see the Oracle Solaris Cluster 4.1 Release Notes.

Configuration Requirements


Caution

Caution - Your data service configuration might not be supported if you do not adhere to these requirements.


Use the requirements in this section to plan the installation and configuration of Oracle Solaris Cluster HA for WebLogic Server. These requirements apply to Oracle Solaris Cluster HA for WebLogic Server only. You must meet these requirements before you proceed with your Oracle Solaris Cluster HA for WebLogic Server installation and configuration.

For requirements that apply to all data services, see Configuration Guidelines for Oracle Solaris Cluster Data Services in Oracle Solaris Cluster Data Services Planning and Administration Guide.

Standard Data Service Configurations

Use the standard configurations in this section to plan the installation and configuration of Oracle Solaris Cluster HA for WebLogic Server. Oracle Solaris Cluster HA for WebLogic Server supports the standard configurations in this section.

In addition to the standard configurations provided in this section, the following WebLogic ServerWebLogic Server configurations are possible.


Note - The WebLogic Server can be configured either as a failover data service, multi-instance data service, or multi-master data service.


Oracle Solaris Cluster HA for WebLogic Server might support additional configurations. However, you must contact your Oracle service provider for information about additional configurations.

WebLogic Server Configured as a Failover Resource

Simple Configuration

This simple configuration for Oracle Solaris Cluster HA for WebLogic Server uses two resource groups configured as follows.

RG1 and RG2 are failover resource groups.

This configuration is possible only if the WebLogic Server is installed on a global file system. See Figure 1-1 for an illustration of this configuration.

Figure 1-1 Oracle Solaris Cluster HA for WebLogic Server Simple Configuration

image:Illustration: The preceding context describes a simple configuration for WebLogic Server.
Configuration 1

In this configuration, RG1, RG2, RG3, and RG4 are failover resource groups configured as follows.

This configuration is possible only if the WebLogic Server is installed on a global file system.

Configuration 2

In this configuration, RG1, RG2, and RG3 are failover resource groups configured as follows.

This configuration is possible only if the WebLogic Server is installed on a global file system.

Configuration 3

If the WebLogic Server is installed on a failover file system by using HAStoragePlus, all the WebLogic Server instances must be configured in the same failover resource group that has a dependency on the failover file system.

RG1 contains logical-host-resource resources and all Administration and Managed-Server resources.

For information about how to register a resource with dependency on an HAStoragePlus resource, see Enabling Highly Available Local File Systems in Oracle Solaris Cluster Data Services Planning and Administration Guide.

See Figure 1-2 for an illustration of this configuration.

WebLogic Servers Configured as a Multi-Master Resource

This example illustrates a multi-master configuration for Oracle Solaris Cluster HA for Oracle WebLogic Server (configured as a cluster).

In multi-master data service configuration, the WebLogic Server resource is used in a scalable resource group. The WebLogic Server managed server resource is online on multiple nodes at the same time.

In this configuration shown in Figure 1-3, a single resource group managed-server-rg includes the managed server resources running on Node 1 and Node 2. Each managed server resource depends on a logical host resource and group that contains only one node.

Figure 1-3 Oracle WebLogic Server Configured as a Multi-Master Resource

image:This graphic shows WebLogic Server configured as a multi-master resource.

WebLogic Servers Configured as Multi-Instance

Multi-instance is an application configuration topology where multiple instances of the same application provide an aggregation of services. This topology can be achieved independently of using a data service because you can manually start and stop the instances on the cluster nodes. When HA of such instances is required, you can enable a data service for the instances by creating multiple single-node resource groups or a few multi-master resource groups.

The diagram in Figure 1-4 illustrates a multi-instance configuration using single-node resource groups. A single-node resource group is created for each of the managed server resources. The resource groups are represented by managed-server-n1–rg and managed-server-n2–rg in the diagram. Each resource group has a strong positive affinity on a storage resource group hasp–rg and a logical host resource group whose primary node is the node containing the managed server resource group.
