Location of OCR Files


Oracle Cluster Registry (OCR) File location :

Need to find the location of OCR but your CRS is down. Then how we can find?

Below are the methods from which we can find out where your OCR files are stored.
  1. When CRS is up & running
  2. When CRS is down or UP

##########################
#  1) When CRS is Up & Running

Set ASM environment or crs environment to run the below command.


 ocrcheck 

+ASM3 @ myhost03:/
 ocrcheck

+ASM3 @ myhost03:/
