Manually Registering Oracle Resource DLL Files

Oracle Real Application Clusters Guard provides resource dynamic-link library (DLL) files for the Oracle Real Application Clusters database server. The DLL files enable the Cluster Service to communicate and manage the Oracle Real Application Clusters database resource.

The following topics are discussed in this appendix:

Registering and Unregistering the Oracle Resource DLL Files	Section B.2

B.1 Oracle Resource DLL Files

Oracle Services for MSCS includes the resource DLL files shown in Table B-1. These files enable MSCS to communicate with and manage the Oracle resource types.

Table B-1  Oracle Resource DLL Files

File	Type	Description
FsResOdbs.dll	Oracle Real Application Clusters database instance and Oracle TNS Listener resource type DLL file	Provides functions to allow the cluster to bring an Oracle resource online or offline and check the health of the resource through Is Alive polling. When the resource is online, the Oracle resource DLL guarantees that the resource is accessible by the client. Otherwise, the Is Alive polling fails.
FsResOpsInstEx.dll	Oracle Real Application Clusters database instance resource DLL extension file	Used by MSCS Cluster Administrator to display the properties of the Oracle Real Application Clusters database instance resource.
FsResTnsLsnrEx.dll	Oracle TNS Listener resource DLL extension file	Used by MSCS Cluster Administrator to display the properties of the Oracle TNS Listener resource.

B.2 Registering and Unregistering the Oracle Resource DLL Files

Typically, the Oracle Real Application Clusters Guard Verify Cluster operation automatically verifies the Oracle resource DLL files and their registration with the MSCS software. If the Verify Cluster operation finds that the DLL files are not registered, it registers them with the MSCS software. Using the Verify Cluster operation is the preferred method for registering DLL files.

However, if you find that the Oracle resource DLL files are not registered properly, you can use the commands in Section B.2.1 and Section B.2.2 to manually register or unregister them.

B.2.1 Oracle Resource DLL Files

To register the Oracle resource DLL files, use the following commands

fssvr /register "Oracle Real Application Clusters Instance" FsResOdbs.dll
fssvr /register "Oracle TNS Listener" FsResOdbs.dll

To unregister the Oracle resource DLL files, use the following commands:

fssvr /unregister "Oracle Real Application Clusters Instance"
fssvr /unregister "Oracle TNS Listener"

B.2.2 Oracle Resource Administrator Extension DLL Files

To register the Oracle resource administrator extension DLL files on the cluster nodes, use the following commands:

fsregadm /r FsResOpsInstEx.dll
fsregadm /r FsResTnsLsnrEx.dll

To unregister the Oracle resource administrator extension DLL files on the cluster nodes, use the following commands:

fsregadm /u FsResOpsInstEx.dll
fsregadm /u FsResTnsLsnrEx.dll

If MSCS Cluster Administrator is installed on a node that is not a member of a cluster, you need to register the Oracle database resource administrator extension DLL with the cluster so that you can view Oracle database resource parameters from the MSCS Cluster Administrator. To register, use the fsregadm command. You must issue the command from the bin directory where Oracle Real Application Clusters Guard Manager is installed (because Oracle Real Application Clusters Guard Manager is not in the path environment variable).

For example:

fsregadm /r /c Cluster1 FsResOpsInstEx.dll
fsregadm /r /c Cluster1 FsResTnsLsnrEx.dll

You must specify the cluster name with the /c option or the command will fail.
