oracle 10g RAC [恢複OCR]

----查詢OCR狀態：
# /oracle/product/10g/crs/bin/ocrcheck            
PROT-601: Failed to initialize ocrcheck

 
---------替換原OCR磁碟，出錯：
# /oracle/product/10g/crs/bin/ocrconfig -replace ocr'/dev/rdsk/c5t600A0B80005AD8BC0000020000000000d0s7'
/oracle/product/10g/crs/bin/ocrconfig -replace ocrmirror'/dev/rdsk/c5t600A0B80005AD8BC0000020000000001d0s7'
PROT-1: Failed to initialize ocrconfig

---------用repair選項替換原OCR磁碟：
# /oracle/product/10g/crs/bin/ocrconfig -repair ocr '/dev/rdsk/c5t600A0B80005AD8BC0000020000000000d0s7'
# /oracle/product/10g/crs/bin/ocrconfig -repair ocrmirror '/dev/rdsk/c5t600A0B80005AD8BC0000020000000001d0s7'

 
---------使用自動備份的ocr檔案來恢複到新的OCR磁碟：
# /oracle/product/10g/crs/bin/ocrconfig -restore '/oracle/product/10g/crs/cdata/crs/backup00.ocr'

此處需注意新的磁碟容量要比原來的磁碟大，否則在恢複是會遇到錯誤PROT-22: Storage too small，這是
Oracle的一個Bug
