Working with OCRDUMP

Dump the contents of OCR and count the number of lines.  If you dump the OCR as root, you will see more information than grid/oracle user because information in the OCR is organized by keys that are associated with privileges.  See examples below:

As oracle or grid user:
ocrdump -stdout | wc -l
489

As root:
ocrdump -stdout | wc -l
2993

To dump the OCR content using XML format for the first 50 lines
              ocrdump -stdout -xml | head -50

To dump current ocr
                ocrdump -xml /apps/oracle/dump_current_ocr.xml

Dump the backup contents of a OCR in XML format, then compare it with the current OCR to detect any changes..
