Oracle RAC OCR VOTE 迁移替换
来源：互联网 发布：用友软件官方网 编辑：程序博客网 时间：2024/05/22 12:14
OS：Centos 6.8
数据库：11.2.0.4
节点：RAC1,RAC2,RAC3
测试目的：将ocr和votedisk从+OCR_VOTING 迁移至+OCR_VOTING_NEW上
具体步骤：
1.准备工作，在RAC 上创建一个+OCR_VOTING_NEW 磁盘组，这里利用asmca进行创建（也可以用命令）创建OCR_VOTING_NEW
这里在asm里就可以查看到（新建的OCR_VOTING_NEW 已经创建成功并且已经mount状态）
+ASM1:/home/grid@rac1>asmcmd -p
ASMCMD [+] > lsdg

MOUNTED NORMAL N 512 4096 1048576 12288 11877 4096 3890 0 N OCR_VOTING_NEW/
2.替换OCR
+ASM1:/home/grid@rac1>ocrcheck
Status of Oracle Cluster Registry is as follows :

注意这里查看crs日志，我们发现OCR已经替换，
2017-03-06 09:02:22.160:
[crsd(8988)]CRS-1007:The OCR/OCR mirror location was replaced by +OCR_VOTING_NEW.
查看ocr.loc
+ASM1:/home/grid@rac1>more /etc/oracle/ocr.loc
#Device/file +OCR_VOTING getting replaced by device +OCR_VOTING_NEW
ocrconfig_loc=+OCR_VOTING_NEW
local_only=false
+ASM1:/home/grid@rac1>
3.迁移OCR //如果在日志里已经查看OCR 已经替换成功，如上所示，这步可以不执行（执行也不会有影响）
[root@rac1 bin]# /u01/app/11.2.0/grid_1/bin/ocrconfig -replace +OCR_VOTING -replacement +OCR_VOTING_NEW
PROT-29: The Oracle Cluster Registry location is already configured
4.迁移votdisk
+ASM1:/home/grid@rac1>crsctl query css votedisk
