今天就跟大家聊聊有关12c如何在集群操作rac与rac one node互相转换,可能很多人都不太了解,为了让大家更加了解,小编给大家总结了以下内容,希望大家根据这篇文章可以有所收获。
-- 首先在集群里停掉2号节点的实例
[oracle@host01 app]$ srvctl stop instance -d racdb -i racdb_2
--查看rac的类型,目前显示为(Type: RAC)
[oracle@host01 app]$ srvctl config database -d racdb
Database unique name: racdb
Database name: racdb
Oracle home: /u01/app/oracle/product/12.1.0/db_1

-- 转换成rac one node类型
[oracle@host01 app]$ srvctl convert database -d racdb -c RACONENODE
-- 再查看rac的类型,此时显示(Type: RACOneNode)
[oracle@host01 app]$ srvctl config database -d racdb
Database unique name: racdb

-- 尝试再重新转换回rac类型
[oracle@host01 app]$ srvctl convert database -d racdb -c RAC
-- 查看rac的类型,已经变成rac了,而且在两个节点上的实例也被起来了
[oracle@host01 app]$ srvctl config database -d racdb

-- 再重新转换回rac one node
[oracle@host01 app]$ srvctl convert database -d racdb -c RACONENODE
PRCD-1154 : Failed to convert the configuration of cluster database racdb into its equivalent RAC One Node database configuration because cluster database is running on more than one server [host02, host01]
-- 提示有两个节点在跑,关掉2号节点
[oracle@host01 app]$ srvctl stop instance -d racdb -i racdb_2
PRCD-1315 : failed to stop instances for database racdb
PRCR-1014 : Failed to stop resource ora.racdb.db
PRCR-1065 : Failed to stop resource ora.racdb.db
CRS-2529: Unable to act on 'ora.racdb.db' because that would require stopping or relocating 'ora.racdb.racserv.svc', but the force option was not specified
-- 提示要先关掉racserv这个service才能关闭2号节点实例
[oracle@host01 app]$ srvctl stop service -d RACDB -s racserv
-- 再次关闭实例
[oracle@host01 app]$ srvctl stop instance -d racdb -i racdb_2
-- 转换rac至rac one node
[oracle@host01 app]$ srvctl convert database -d racdb -c RACONENODE
-- 查状态,转换成功
