OCRCONFIG Command Tips Oracle Database Tips by Donald Burleson

Importing Oracle Cluster Registry Content on Windows-Based Systems

    1.   Stop the following OCR clients using the Service Control Panel:

         OracleClusterVolumeService, OracleCMService, OracleEVMService,
         OracleCSService, and the OracleCRService.

2. Import a valid OCR export file using the ocrconfig -import command from one of the cluster nodes. 

3. Restart all of the affected services on all cluster nodes.

The OCRCONFIG Tool Command Syntax and Options

You execute OCR commands, such as OCRCONFIG, from a user with administrative privileges on UNIX-based platforms or from a user with Administrator privileges on Windows-based systems. The OCRCONFIG command syntax is as follows:

ocrconfig -<option>

The OCRCONFIG Tool Command Syntax and Options

To export the OCR contents to a binary file, for example, use the OCRCONFIG command with the export syntax (where file_name is the file to which you want to export the OCR contents):

ocrconfig -export file_name

The OCRCONFIG command export file is not editable. If OCR clients such as the clusterware are running when you attempt an export, then Oracle will report an OCRCONFIG error.

To make a backup, use the OCRCONFIG tool with the showbackup option to identify the backup files, and then copy each file to a location that is redundant to the location of the original OCR backup file. This ensures that there are at least two copies of each OCR backup file.

ocrconfig -showbackup

Oracle also recommends that the OCR location reside on RAID arrays. If possible, use a backup location that is shared by all nodes in the cluster. The default target location of each OCR backup file is as follows where <cluster name> is the name assigned to the cluster when CRS was installed:

/cdata/

This OCRCONFIG backup location can be changed by using the following syntax:

ocrconfig -backuploc

You can also run the OCRCONFIG repair and OCRCONFIG replace commands.

This OCRCONFIG command must be run as root user when HA service is started but CRS must be stopped.

ocrconfig -repair -replace +DAT2 -replacement +DATA1
