ocrcheck commands in Oracle RAC 19c

 

In Oracle RAC (Real Application Clusters), ocrcheck is a command-line utility used to check the status of Oracle Cluster Registry (OCR) in a cluster environment. The OCR stores important configuration data for Oracle Clusterware, such as cluster node information, voting disk locations, and other configuration details.

Check OCR Status: To check the status of the OCR and verify its integrity, use the following command:

[root@testrac1 ~]# cd /u01/app/19.0.0.0/grid/bin/ [root@testrac1 bin]# ./ocrcheck Status of Oracle Cluster Registry is as follows :          Version                  :          4          Total space (kbytes)     :     901284          Used space (kbytes)      :      84572          Available space (kbytes) :     816712          ID                       : 2059301600          Device/File Name         :      +DATA                                     Device/File integrity check succeeded                                       Device/File not configured                                       Device/File not configured                                       Device/File not configured                                       Device/File not configured            Cluster registry integrity check succeeded            Logical corruption check succeeded

 

To check the local OCR copy on the node where you run the command.

[root@testrac1 bin]# ./ocrcheck -local Status of Oracle Local Registry is as follows :          Version                  :          4          Total space (kbytes)     :     491684          Used space (kbytes)      :      83324          Available space (kbytes) :     408360          ID                       : 1502315622          Device/File Name         : /u01/app/grid/crsdata/testrac1/olr/testrac1_19.olr                                     Device/File integrity check succeeded            Local registry integrity check succeeded            Logical corruption check succeeded

 

Check OCR Configuration: If you need more detailed information about the OCR configuration, including its location, you can use:

[root@testrac1 bin]# ./ocrcheck -config Oracle Cluster Registry configuration is :          Device/File Name         :      +DATA

 

Check OCR local location

[root@testrac1 bin]# ./ocrcheck -local -config Oracle Local Registry configuration is :          Device/File Name         : /u01/app/grid/crsdata/testrac1/olr/testrac1_19.olr
