Verifying the Installation and Configuration of Support for Oracle RAC

After you install, register, and configure Support for Oracle RAC, verify the installation and configuration. Verifying the Support for Oracle RAC installation and configuration determines whether resources and resource groups for Oracle RAC behave as required.

Offline-restart dependencies between resources ensure that, if the independent resource is about to be taken offline, the dependent resource is taken offline first. The dependent resource remains offline until the independent resource is restarted. The procedures in this section explain how to verify that these dependencies are correctly set. For detailed information about offline-restart dependencies, see the description of the resource_dependencies_offline_restart resource property in the r_properties(5) man page.

Verifying the installation and configuration of Support for Oracle RAC involves the following tasks:

Verifying the configuration of the Oracle RAC framework resource group and, if used, verifying the configuration of the multiple-owner volume-manager framework resource group. See How to Verify the Configuration of the Oracle RAC Framework Resource Group and How to Verify the Configuration of the Multiple-Owner Volume-Manager Framework Resource Group.
Verifying the configuration of storage resources for Oracle files. See How to Verify the Configuration of Storage Resources for Oracle Files.
Verifying the configuration of resources for Oracle RAC database instances. See How to Verify the Configuration of Resources for Oracle RAC Database Instances.
Verifying the correct behavior for shutdown and booting of the cluster. See How to Verify the Correct Behavior for Shutdown and Booting of the Cluster.

How to Verify the Configuration of the Oracle RAC Framework Resource Group

The Oracle RAC framework resource group is created when the task in Registering and Configuring the Oracle RAC Framework Resource Group is performed.

Become superuser on a cluster node or assume a role that provides solaris.cluster.read and solaris.cluster.admin RBAC authorizations.
Verify that the Oracle RAC framework resource group is correctly configured.
```
# clresourcegroup show rac-fmk-rg
```
rac-fmk-rg

Specifies the name of the Oracle RAC framework resource group.
If the Oracle RAC framework resource group is not already online, bring online the Oracle RAC framework resource group.
```
# clresourcegroup online rac-fmwk-rg
```
rac-fmk-rg

Specifies the name of the Oracle RAC framework resource group.
Verify that the Oracle RAC framework resource group is online.
```
# clresourcegroup status
```

How to Verify the Configuration of the Multiple-Owner Volume-Manager Framework Resource Group

Perform this procedure if you use a multiple-owner volume-manager framework resource group to contain the volume manager resources that are used by your RAC configuration.

Become superuser on a cluster node or assume a role that provides solaris.cluster.read and solaris.cluster.admin RBAC authorizations.
Verify that the multiple-owner volume-manager framework resource group is correctly configured.
```
# clresourcegroup show vucmm-fmk-rg
```
vucmm-fmk-rg

Specifies the name of the multiple-owner volume-manager framework resource group.
If the multiple-owner volume-manager framework resource group is not already online, bring online the multiple-owner volume-manager framework resource group.
```
# clresourcegroup online vucmm-fmwk-rg
```
vucmm-fmk-rg

Specifies the name of the multiple-owner volume-manager framework resource group.
Verify that the RAC resource group is online.
```
# clresourcegroup status
```

How to Verify the Configuration of Storage Resources for Oracle Files

Perform this task only if your configuration of storage management schemes requires storage resources for Oracle files.

Become superuser on a cluster node.
Verify that all resource groups that contain storage resources for Oracle files are correctly configured.
```
# clresourcegroup show rac-storage-rg-list
```
rac-storage-rg-list

Specifies a comma-separated list of resource groups that contain storage resources for Oracle files.
Take offline the resource group that contains the resources on which the RAC database resource depends.
```
# clresourcegroup offline rac-storage-rg
```
rac-storage-rg
Specifies the name of the resource group that contains the resources on which the RAC database resource depends. The resource group to take offline depends on your choice of storage management schemes for Oracle files.
- If you are using a shared file system for Oracle files, take offline the resource group that contains scalable file-system mount-point resources.
- If you are using a volume manager without a file system for Oracle files, take offline the resource group that contains scalable device-group resources.
This step might require several minutes to complete.
Verify that the resource groups for Oracle RAC behave as follows:
- The status of the resource group that you took offline in Step 3 is offline.
- The status of the Oracle RAC database resource group is offline.
- The status of the Oracle RAC framework resource group is pending online blocked.
```
# clresourcegroup status
```
Verify that the Oracle Grid Infrastructure resources are offline.
To verify that the Oracle Grid Infrastructure resources are offline, consult the system messages file to find messages to indicate that Oracle Grid Infrastructure resources are being shut down.
Bring online the resource group that you took offline in Step 3.
```
# clresourcegroup online rac-storage-rg
```
rac-storage-rg

Specifies the name of the resource group that you took offline in Step 3.

This step might require several minutes to complete.
On each node, restart the Oracle Grid Infrastructure.
```
# Grid_home/bin/crsctl start crs
Startup will be queued to init within 30 seconds.
```
Grid_home

Specifies the Oracle Grid Infrastructure home directory. This directory contains the Oracle Grid Infrastructure binary files and Oracle Grid Infrastructure configuration files.

This step might require several minutes to complete.
On each node, verify that the Oracle Grid Infrastructure resources are online.
Use the Oracle command crstat for this purpose.
```
# Grid_home/bin/crsctl stat res -t
```
Note - The startup of Oracle Grid Infrastructure on all nodes might require several minutes to complete. If you perform this step before the Oracle Grid Infrastructure resources are online on all nodes, the status on some nodes might be offline. In this situation, repeat this step until the status of the Oracle Grid Infrastructure is online on all nodes.
Verify that all resource groups for Oracle RAC are online.
```
# clresourcegroup status
```
Note - Bringing online the resource group that contains the resources on which the RAC database resource depends also brings online the RAC database resource group. If you perform this step before the RAC database resource group is online on all nodes, the status on some nodes might be online faulted. In this situation, repeat this step until the status of the RAC database resource group is online on all nodes.

How to Verify the Configuration of Resources for Oracle RAC Database Instances

Resources for Oracle RAC database instances are created when the tasks in one of the following sections are performed:

Become superuser on a cluster node.
Verify that the database resource group is correctly configured.
```
# clresourcegroup show rac-db-rg
```
rac-db-rg

Specifies the name of the database resource group.
If required, verify that the Oracle Grid Infrastructure resources to represent Oracle Solaris Cluster storage resources are correctly configured.
```
# Grid_home/bin/crsctl stat res -t
```
Grid_home

Specifies the Oracle Grid Infrastructure home directory. This directory contains the Oracle Grid Infrastructure binary files and Oracle Grid Infrastructure configuration files.
Disable the Oracle Grid Infrastructure framework resource.
```
# clresource disable -t SUNW.crs_framework +
```
This step might require several minutes to complete.
Verify that the Oracle Grid Infrastructure resources are offline.
1. Attempt to obtain the status of Oracle Grid Infrastructure resources.
  Use the Oracle command crstat for this purpose.
```
# Grid_home/bin/crsctl stat res -t
CRS-0184: Cannot communicate with the CRS daemon.
```
  Grid_home
  
  Specifies the Oracle Grid Infrastructure home directory. This directory contains the Oracle Grid Infrastructure binary files and Oracle Grid Infrastructure configuration files.
2. Consult the system messages file to find messages to indicate that Oracle Grid Infrastructure resources are being shut down.
Verify that the following resources are offline on all nodes:
- The Oracle Grid Infrastructure framework resource
- The RAC database resource
```
# clresource status -t SUNW.crs_framework,SUNW.scalable_rac_server_proxy +
```
On each node, restart the Oracle Grid Infrastructure.
```
# Grid_home/bin/crsctl start crs
Startup will be queued to init within 30 seconds.
```
Grid_home

Specifies the Oracle Grid Infrastructure home directory. This directory contains the Oracle Grid Infrastructure binary files and Oracle Grid Infrastructure configuration files.

This step might require several minutes to complete.
On each node, verify that the Oracle Grid Infrastructure resources are online.
Use the Oracle command crstat for this purpose.
```
# Grid_home/bin/crsctl stat res -t
```
Note - The startup of Oracle Grid Infrastructure on all nodes might require several minutes to complete. If you perform this step before the Oracle Grid Infrastructure resources are online on all nodes, the status on some nodes might be offline. In this situation, repeat this step until the status of the Oracle Grid Infrastructure is online on all nodes.
Enable the Oracle Grid Infrastructure framework resource.
```
# clresource enable -t SUNW.crs_framework +
```
This step might require several minutes to complete.
Verify that the following resources are online on all nodes:
- The Oracle Grid Infrastructure framework resource
- The RAC database resource
```
# clresource status -t SUNW.crs_framework,SUNW.scalable_rac_server_proxy +
```
Note - Enabling the Oracle Grid Infrastructure framework resource also enable the RAC database resource. If you perform this step before the RAC database resource is enabled on all nodes, the status on some nodes might be offline. In this situation, repeat this step until the status of the RAC database resource is online on all nodes.

How to Verify the Correct Behavior for Shutdown and Booting of the Cluster

If your configuration of Support for Oracle RAC is correct, Oracle Solaris Cluster ensures that Oracle RAC is stopped and started correctly when you shut down and boot the cluster.

Caution - This task requires downtime. If you are verifying the installation and configuration of Support for Oracle RAC on a production cluster where other data services are running, omit this task.

Shut down the cluster.
For instructions for performing this task, see How to Shut Down a Cluster in Oracle Solaris Cluster System Administration Guide.
Confirm that the cluster shuts down correctly.
Boot the cluster.
For instructions for performing this task, see How to Boot a Cluster in Oracle Solaris Cluster System Administration Guide.
Confirm that the cluster starts correctly.
Verify that all Oracle RAC resource groups and their resources are online.
```
# clresourcegroup status
```
Note - The bringing online of all Oracle RAC resource groups might require several minutes to complete. If you perform this step before the resource groups are enabled on all nodes, the status on some nodes might be offline. In this situation, repeat this step until the status of all Oracle RAC resource groups is online on all nodes.
