在线迁移OCR遇到报错：PROT-16

在线迁移OCR遇到报错：PROT-16

现象：

[root@HeiLJUC01 ~]# /oracle/app/11gR1/crs/bin/ocrconfig -replace ocr /dev/raw/raw9

PROT-16: Internal Error

[root@HeiLJUC01 ~]# /oracle/app/11gR1/crs/bin/ocrconfig -replace ocr /dev/raw/raw9

PROT-16: Internal Error

分析：

用ocrcheck查看没有mirr ocr：

[root@HeiLJUC01 ~]# /oracle/app/11gR1/crs/bin/ocrcheck

Status of Oracle Cluster Registry is as follows :

Version : 2

Total space (kbytes) : 3142964

Used space (kbytes) : 8232

Available space (kbytes) : 3134732

ID : 1765612463

Device/File Name : /dev/raw/raw1

Device/File integrity check succeeded

Cluster registry integrity check succeeded

Logical corruption check succeeded

没有Mirr ocr的情况下，在线迁移ocr是不允许的，Oracle这样设置是基于安全性及可回退的保障来考虑的，因此需要先添加Mirr ocr。

解决方法：

1、先添加Mirr ocr

[root@HeiLJUC01 ~]# /oracle/app/11gR1/crs/bin/ocrconfig -replace ocrmirror /dev/raw/raw10

[root@HeiLJUC01 ~]# /oracle/app/11gR1/crs/bin/ocrcheck

Status of Oracle Cluster Registry is as follows :

Version : 2

Total space (kbytes) : 3142964

Used space (kbytes) : 8232

Available space (kbytes) : 3134732

ID : 1765612463

Device/File Name : /dev/raw/raw1

Device/File integrity check succeeded

Device/File Name : /dev/raw/raw10 <===Mirr ocr已添加上

Device/File integrity check succeeded

Cluster registry integrity check succeeded

Logical corruption check succeeded

2，再迁移ocr

[root@HeiLJUC01 ~]# /oracle/app/11gR1/crs/bin/ocrconfig -replace ocr /dev/raw/raw9

[root@HeiLJUC01 ~]# /oracle/app/11gR1/crs/bin/ocrcheck

\Status of Oracle Cluster Registry is as follows :

Version : 2

Total space (kbytes) : 3142964

Used space (kbytes) : 8232

Available space (kbytes) : 3134732

添加Mirr ocr之后，就可以很方便的在线迁移OCR了。
