導出導入
可以用raw的命令來備份和恢復，不過ocrconfig提供了專門的命令來導出和導入還提供了鏡像的方法

OCR手動導出:ocrconfig -export /tmp/ocr_bak
OCR手動導入:ocrconfig -import /tmp/ocr_bak
恢復OCR ocrconfig -restore /opt/product/10.2.0.1/crs/cdata/crs/backup01.ocr
添加OCR鏡像盤:

創(chuàng)建用于鏡像OCR的RAW設備,比如為:/dev/raw/ocrcopied
用ocrconfig –export 導出OCR的信息
編輯/etc/oracle/ocr.loc文件,添加ocrmirrorconfig_loc行
$ cat ocr.loc
ocrconfig_loc=/dev/raw/raw2
ocrmirrorconfig_loc=/dev/raw/ocrcopied
local_only=FALSE
用ocrconfig –import 導入OCR的信息
