导出导入
可以用raw的命令来备份和恢复，不过ocrconfig提供了专门的命令来导出和导入还提供了镜像的方法
OCR手动导出:ocrconfig -export /tmp/ocr_bak
OCR手动导入:ocrconfig -import /tmp/ocr_bak
恢复OCR ocrconfig -restore /opt/product/10.2.0.1/crs/cdata/crs/backup01.ocr
添加OCR镜像盘:
创建用于镜像OCR的RAW设备,比如为:/dev/raw/ocrcopied
用ocrconfig –export 导出OCR的信息
编辑/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 导入OCR的信息
