The OCRCHECK utility displays the version of the OCR's block format, total space available and used space, OCRID, and the OCR locations that you have configured. OCRCHECK performs a block-by-block checksum operation for all of the blocks in all of the OCRs that you have configured. It also returns an individual status for each file and a result for the overall OCR integrity check.
Note:
Oracle supports using the ocrcheck command when, at a minimum, the Oracle Cluster Ready Services stack is OFFLINE on all nodes in the cluster because the command will run even if the stack is ONLINE but it can falsely indicate that the OCR is corrupt if the check happens while an update to OCR is underway.
