There is an automatic backup mechanism for OCR. The default location is : $ORA_CRS_HOME\cdata\”clustername”\ To display backups : ocrconfig -showbackupTo restore a backup : ocrconfig -restore The automatic backup mechanism keeps upto about a week old copy. So, if you want to retain a backup copy more than that, then you should copy that “backup” file to some other name. Unfortunately there are a couple of bugs regarding backup file manipulation, and changing default backup dir on Windows. These will be fixed in 10.1.0.4. OCR backup on Windows are absent. Only file in the backup directory is temp.ocr which would be the last backup. You can restore this most recent backup by using the command ocr -restore temp.ocr If you want to take a logical copy of OCR at any time use : ocrconfig -export , and use -import option to restore the contents back.
