Registering and Configuring HA for Oracle Web Tier Components

The sections that follow contain instructions for registering and configuring the HA for Oracle Web Tier component resources. For information about the extension properties, see Appendix A, HA for Oracle Web Tier Extension Properties. The Tunable entry indicates when you can update a property.

See the rt_properties(5), r_properties(5), and rg_properties(5) man pages for details on all of the Oracle Solaris Cluster extension properties.

To set an extension property of a resource, include the following option in the clresource command that creates or modifies the resource:

-p property=value

-p property: Identifies the extension property that you are setting.
value: 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 Oracle Solaris Cluster Data Services Planning and Administration Guide to configure resources after the resources are created.

How to Register and Configure HA for Oracle Web Tier

Complete the registration and configuration on any cluster member.

On a cluster member, become superuser or assume a role that provides solaris.cluster.admin and solaris.cluster.modify RBAC authorization.
Register the ORCL.ohs and ORCL.opmn resource types for the data service.
```
# clresourcetype register ORCL.ohs ORCL.opmn
```
Create the application resources in the application failover resource group.
You must create two resources in the application failover resource group, one for the Oracle Process Management and Notification Server component and one for the Oracle HTTP Server component.
1. Create the Oracle Process Management and Notification Server resource.
```
# clresource create -g resource-group
-t ORCL.opmn \
-p Oracle_home=ORACLE_HOME-path \
-p Instance_Name=instance-name \
[-p Debug_level=debug-level] \
[-p Resource_project_name=project-name] \
[-p Resource_dependencies_offline_restart=offline-restart-resource-dependencies[,…]] \
resource
```
  resource-group
  
  Specifies the name of the failover resource group created in Step 2 of How to Install and Configure the Oracle Web Tier Software and Resources.
  
  -p Oracle_home=ORACLE_HOME-path
  
  Specifies the absolute path to the Oracle Web Tier software installation. This is normally a subdirectory of the Oracle Fusion Middleware installation.
  
  -p Instance_Name=instance-name
  
  Specifies the OPMN instance name that was supplied when the Oracle Web Tier software was configured. The default value is instance1.
  
  -p Debug_level=debug-level
  
  An optional property that specifies the amount of debugging information produced by the resource and fault probe. The default value is 0 which results in no debugging output.
  
  -p Resource_project_name=project-name
  
  An optional property that specifies the project under which the OPMN resource should run. The default value is the project called default.
  All processes that are started by the OPMN resource inherit this project setting. This includes any Oracle HTTP server that is started by OPMN. Consequently, for any OHS resource that is dependent on an OPMN resource, the value of the Resource_project_name property that is set for the OHS resource must be identical to the value that is set for the OPMN resource or left as the default.
  
  -p Resource_dependencies_offline_restart=resource-dependencies-offline-restart[,...]
  
  An optional property that specifies a comma-separated list of resources on which this resource has an offline restart dependency. This list must include a dependency on the storage resource created in Step 5 of How to Install and Configure the Oracle Web Tier Software and Resources, with the exception of configurations where a cluster file system is used in the global zone. Furthermore, the storage resource dependency must have {local_node} scope.
2. Create the Oracle HTTP Server (OHS) resource.
```
# clresource create -g resource-group \
-t ORCL.ohs \
-p Component_instance=component-instance-name \
[-p Debug_level=debug-level] \
-p Resource_dependencies=ohs-lh \
-p Resource_dependencies_offline_restart=opmn-rs \
resource
```
  resource-group
  
  Specifies the name of the failover resource group created in Step 2 of How to Install and Configure the Oracle Web Tier Software and Resources.
  
  -p Component_instance=component-instance-name
  
  Specifies the name of the Oracle HTTP Server component instance that is under the control of the Oracle Process Management and Notification Server component configured in Step a. The default value is ohs1.
  
  -p Debug_level=debug-level
  
  An optional property that specifies the amount of debugging information produced by the resource and fault probe. The default value is 0 which results in no debugging output.
  
  -p Resource_dependencies=ohs-lh
  
  Specifies the logical hostname resource created in Step 4 of How to Install and Configure the Oracle Web Tier Software and Resources, on which this resource has a dependency.
  
  -p Resource_dependencies_offline_restart=opmn-rs
  
  Specifies a dependency with {local_node} scope on the Oracle Process Management and Notification Server resource created in Step a, on which this resource has an offline-restart dependency.

Example 1-1 Registering HA for Oracle Web Tier on a Highly Available Local File System

This example shows how to register an Oracle Web Tier service that uses a highly available local file system on a two-node cluster. The following are the sample names used in the commands:

Node names: phys-schost-1, phys-schost-2
Zpool name (for highly available local file systems): ohspool
Logical hostname: schost-1
Resource group (for all of the resources): ohs-rg
Logical hostname resource: ohs-lh-rs
HAStoragePlus storage resource: ohs-hasp-rs
Oracle HTTP Server component resource: ohs-rs
Oracle Process Management and Notification Server component resource: opmn-rs

Add a failover resource group to contain all of the resources
# clresourcegroup create ohs-rg

Bring the failover resource group online
# clresourcegroup online -emM ohs-rg

Add the logical hostname resource to the failover resource group
# clreslogicalhostname create -g ohs-rg -h schost-1 ohs-lh-rs 

Register the HAStoragePlus resource type, if it is not already registered

Logical hostname resource: ohs-lh-rs
HAStoragePlus storage resource: ohs-hasp-rs
Oracle HTTP Server component resource: ohs-rs
Oracle Process Management and Notification Server component resource: opmn-rs

Add a failover resource group to contain the failover resources
# clresourcegroup create ohs-rg 

Bring the failover resource group online
# clresourcegroup online -emM ohs-rg

Add a scalable resource group to contain the storage resource
# clresourcegroup create -S -p Maximum_primaries=2 -p Desired_primaries=2 stor-rg 

Register the HAStoragePlus resource type, if it is not already registered
# clresourcetype register SUNW.HAStoragePlus

Add the HAStoragePlus resource to the scalable resource group
# clresource create -g stor-rg \
-t SUNW.HAStoragePlus -p FileSystemMountPoints=/global/ohs ohs-hasp-rs

Bring the scalable resource group online
# clresourcegroup online -emM stor-rg

Add the logical hostname resource to the failover resource group
# clreslogicalhostname create -g ohs-rg -h zchost-lh-1 ohs-lh-rs 

Register the Oracle HTTP Server resource type
# clresourcetype register ORCL.ohs

Register the Oracle Process Management and Notification Server resource type
# clresourcetype register ORCL.opmn

Install and configure the Oracle Web Tier software

Add the Oracle Process Management and Notification Server component resource to the failover resource group
# clresource create -g ohs-rg \
-t ORCL.opmn -p Oracle_home=/ohspool/Oracle/Middleware/Oracle_WT1 \
-p Instance_name=myinstance \
-p Resource_dependencies_offline_restart=ohs-hasp-rs{local_node} opmn-rs
 
Add the Oracle HTTP Server component resource to the failover resource group
# clresource create -g ohs-rg \
-t ORCL.ohs -p Component_instance=myohs \
-p Resource_dependencies=ohs-lh-rs \
-p Resource_dependencies_offline_restart=opmn-rs{local_node} ohs-rs

How to Verify Data Service Installation and Configuration

After you configure HA for Oracle Web Tier, verify that you can open a web page with the network resources (logical hostname) and port number from a web browser. Perform a switchover with the clresourcegroup command to verify that the service continues to run on a secondary node and can be switched back to the original primary.
