CRS on Windows: How To Reinitialize (Accidentally Deleted) OCR and Vote Disk (without a full reinstall of Oracle Clusterware) (Doc ID 557178.1)

Last updated on AUGUST 04, 2018

Applies to:

Oracle Database - Enterprise Edition - Version 10.1.0.2 to 11.1.0.7 [Release 10.1 to 11.1]
Microsoft Windows x64 (64-bit)
Microsoft Windows (32-bit)
Oracle Server Enterprise Edition - Version: 10.1.0.2 to 11.1.0.7


Goal

This document presents a step by step approach to reinitialize the OCR and Vote Disks without performing a full reinstallation of the 10gR2 or 11Gr1 Oracle Clusterware binaries on Windows platforms. 

Note that the procedure in this document is only useful in cases where the Oracle Clusterware Services (including:  OracleCSService, OracleEVMService, OracleCRService are intact). If any of these services are missing (such as in the case during a failed upgrade attempt to a higher clusterware version), Oracle Clusterware reinstall will be required.

 

These steps may be necessary in the following scenarios:

1.  To troubleshoot an installation where the Cluster Configuration Assistant (which calls crssetup.config.bat ) has errored out

OR

2.  For a cluster that was running fine, but the OCR and/or Vote disks have become damaged or unusable
