oracle 11gR2 如何对ocr和vote盘进行镜象

原创 Linux操作系统 作者:paulyibinyi 时间:2010-07-25 23:55:08 0 删除 编辑

   我们都知道11gR2环境中,ocr和vote盘都放在asm磁盘组中,那如何对ocr磁盘组进行

镜象,这篇文章会有介绍:

1.先建立好asm磁盘组,比如我们这建立了asm_dg磁盘组

 

2.检查配置

[root@rac1 bin]# ./ocrcheck

Status of Oracle Cluster Registry is as follows :

         Version                  :          3

         Total space (kbytes)     :     262120

         Used space (kbytes)      :       3200

         Available space (kbytes) :     258920

         ID                       :  997463125

         Device/File Name         :      +DATA

                                    Device/File integrity check succeeded

 

                                    Device/File not configured

 

                                    Device/File not configured

 

                                    Device/File not configured

 

                                    Device/File not configured

 

         Cluster registry integrity check succeeded

 

         Logical corruption check succeeded

 

3.添加磁盘镜象

[root@rac1 bin]# ./ocrconfig -add '+asm_dg';

 

[root@rac1 bin]#

 

4.检查修改后的配置

[root@rac1 bin]# ./ocrcheck

Status of Oracle Cluster Registry is as follows :

         Version                  :          3

         Total space (kbytes)     :     262120

         Used space (kbytes)      :       3200

         Available space (kbytes) :     258920

         ID                       :  997463125

         Device/File Name         :      +DATA

                                    Device/File integrity check succeeded

         Device/File Name         :    +asm_dg

                                    Device/File integrity check succeeded

 

                                    Device/File not configured

 

                                    Device/File not configured

 

                                    Device/File not configured

 

         Cluster registry integrity check succeeded

 

         Logical corruption check succeeded

 

建议asm磁盘组放在不同的raid组上
