Oracle OCR镜像的增加如何正确进行操作？

以下的文章驻澳介绍的是Oracle OCR镜像的增加以及其删除的实际操作步骤，我们大家都知道Oracle OCR记录节点成员配置的相关信息,有以下几种，ASM、instance、listener、VIP等CRS资源的配置信息。

检查Oracle OCR的状态

[root@node3~]#ocrcheck StatusofOracleClusterRegistryisasfollows: Version:2 Totalspace(kbytes):208656 Usedspace(kbytes):6496 Availablespace(kbytes):202160 ID:844916878 Device/FileName:/dev/raw/raw2 Device/Fileintegritychecksucceeded Device/Filenotconfigured Clusterregistryintegritychecksucceeded [root@node3~]#cat/etc/oracle/ocr.loc #Device/file/dev/raw/raw4beingdeleted ocrconfig_loc=/dev/raw/raw2 local_only=false

增加一个镜像

[root@node3~]#ocrconfig-replaceocrmirror/dev/raw/raw4 [root@node3~]#ocrcheck StatusofOracleClusterRegistryisasfollows: Version:2 Totalspace(kbytes):208656 Usedspace(kbytes):6496 Availablespace(kbytes):202160 ID:844916878 Device/FileName:/dev/raw/raw2 Device/Fileintegritychecksucceeded Device/FileName:/dev/raw/raw4 Device/Fileintegritychecksucceeded Clusterregistryintegritychecksucceeded [root@node3~]#cat/etc/oracle/ocr.loc #Device/filegettingreplacedbydevice/dev/raw/raw4 ocrconfig_loc=/dev/raw/raw2 ocrmirrorconfig_loc=/dev/raw/raw4 local_only=false[root@node3~]#ocrconfig-replaceocrmirror/dev/raw/raw6 [root@node3~]#ocrcheck StatusofOracleClusterRegistryisasfollows: Version:2 Totalspace(kbytes):208656 Usedspace(kbytes):6496 Availablespace(kbytes):202160 ID:844916878 Device/FileName:/dev/raw/raw2 Device/Fileintegritychecksucceeded Device/FileName:/dev/raw/raw6 Device/Fileintegritychecksucceeded Clusterregistryintegritychecksucceeded [root@node3~]#cat/etc/oracle/ocr.loc #Device/file/dev/raw/raw4gettingreplacedbydevice/dev/raw/raw6 ocrconfig_loc=/dev/raw/raw2 ocrmirrorconfig_loc=/dev/raw/raw6 local_only=false

Oracle OCR只能有一份镜像，新增加的镜像文件会替换掉原来的镜像。

删除Oracle OCR的镜像文件

[root@node3 ~]# ocrconfig -replace ocrmirror —不带文件路径名

[root@node3~]#ocrcheck StatusofOracleClusterRegistryisasfollows: Version:2 Totalspace(kbytes):208656 Usedspace(kbytes):6496 Availablespace(kbytes):202160 ID:844916878 Device/FileName:/dev/raw/raw2 Device/Fileintegritychecksucceeded Device/Filenotconfigured Clusterregistryintegritychecksucceeded [root@node3~]#cat/etc/oracle/ocr.loc #Device/file/dev/raw/raw6beingdeleted ocrconfig_loc=/dev/raw/raw2 local_only=false

注意如果我们删除了Oracle OCR的主文件,相应的镜像文件自动的变为主文件。

例如：

[root@node3~]#ocrcheck StatusofOracleClusterRegistryisasfollows: Version:2 Totalspace(kbytes):208656 Usedspace(kbytes):6496 Availablespace(kbytes):202160 ID:844916878 Device/FileName:/dev/raw/raw2 Device/Fileintegritychecksucceeded Device/FileName:/dev/raw/raw4 Device/Fileintegritychecksucceeded Clusterregistryintegritychecksucceeded [root@node3~]#ocrconfig-replaceocr [root@node3~]#ocrcheck StatusofOracleClusterRegistryisasfollows: Version:2 Totalspace(kbytes):208656 Usedspace(kbytes):6496 Availablespace(kbytes):202160 ID:844916878 Device/FileName:/dev/raw/raw4 Device/Fileintegritychecksucceeded Device/Filenotconfigured Clusterregistryintegritychecksucceeded 

上述的相关内容就是对Oracle OCR镜像的增加及删除的描述，希望会给你带来一些帮助在此方面。
