Oracle RAC One Node convert to RAC
操作步骤
CopyRight By Jieyancai
环境说明：
Redhat 6.3x64+oracle11.2.0.3 racone+asm
数据库名：zxm 应用服务名：app
目标转换为 RAC zxm1,zxm2
以下操作均用 oracle 用户操作。
1.
转换操作
srvctl stop database -d zxm
srvctl convert database -d zxm -c RAC
2.
移除原来的服务和实例
移除服务：
srvctl remove service -d zxm -s app
移除实例：
srvctl remove instance -d zxm -i zxm_1
srvctl remove instance -d zxm -i zxm_2
查看原来的实例及服务名称：
srvctl config service -d zxm
srvctl config database -d zxm
oracle@rac01:/home/oracle(jyc1)>srvctl config database -d zxm -a
Database unique name: zxm
Database name: zxm

3.
添加实例
srvctl add instance -d zxm -i zxm1 -n rac01
srvctl add instance -d zxm -i zxm2 -n rac02
crsctl stat res -t
oracle@rac01:/home/oracle(jyc1)>srvctl modify instance -d zxm -i zxm1 -s +ASM1
Warning:-s option has been deprecated and will be ignored.
oracle@rac01:/home/oracle(jyc1)>srvctl modify instance -d zxm -i zxm2 -s +ASM2
Warning:-s option has been deprecated and will be ignored.
4.
