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_bakOCR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
