The ocrconfig Tool Command
Syntax and Options
To export the OCR contents to a binary file,
for example, use the ocrconfig command with the following syntax
where file_name is the file to which you want to export the OCR
contents:
ocrconfig
-export file_name
The export file is not editable. If OCR clients
such as the clusterware are running when you attempt an export, then
Oracle will report an error.
Implementing the Oracle Hardware
Assisted Resilient Data (HARD) Initiative for the OCR
The purpose of the Oracle Hardware Assisted
Resilient Data (HARD) initiative is to prevent data corruptions
before they can occur. When HARD is enabled, the OCR writes what are
known as HARD-compatible blocks.
While
data corruptions are rare, they can have a catastrophic effect on a
database, and by extension of the business it supports. By providing
Oracle's data validation algorithms to disk manufacturers and having
these algorithms at work inside storage devices, Oracle, with disk
vendor support, will prevent corrupted data from being written to
the database files on permanent storage. This type of end-to-end
high-level software to low-level hardware validation is currently a
unique capability provided only by Oracle and its storage partners.
