oracle10双机rac停机

停机维护前，数据都expdp/impdp备用机

1 先停RAC数据库，然后关数据库服务器，最后关存储

2 先开存储，在开数据库服务器，开启数据库

一：关rac

1. Ensure that you are logged in as the oracle Linux/ UNIX user.

su - oracle

$ emctl status dbconsole

2. Stop/ shut (stop) down all applications using the Oracle database.

export ORACLE_UNQNAME=mxloan (export ORACLE_UNQNAME=GlobalUniqueName (database SID and not instance SID))

$ emctl stop dbconsole

3. Shut down (stop) all Oracle RAC instances on all nodes.

$ORACLE_HOME/bin/srvctl stop database -d mxloan (-d 数据库名 this command is stoping all the instances)

4. Shut down (stop) all Oracle ASM instances on all nodes. (If you are not using the ASM you must skip this step.)

$ORACLE_HOME/bin/srvctl stop asm -n mxloan1 (-n 节点名)

$ORACLE_HOME/bin/srvctl stop asm -n mxloan2

5. Stop (shut down) the Oracle cluster stack

su - root

cd $CRS_HOME/bin

# ./crsctl stop crs (must be run on each node)

./srvctl stop nodeapps -n node_name -->in 11.2 stops only ONS and eONS because of some dependencies.

开机：

1

su - root

2

su - root

cd $CRS_HOME/bin

# ./crsctl start crs (must be run on each node)

3

su - oracle

$ORACLE_HOME/bin/srvctl start asm -n mxloan1

$ORACLE_HOME/bin/srvctl start asm -n mxloan2

4

$ srvctl start database -d mxloan (srvctl from ORACLE_HOME) (this command is starting all the instances)

5

$ emctl start dbconsole

-------------------------------------------------

其他启停版本

总结

停止RAC： 先停库(实例)，然后ASM ，最后apps

emctl stop dbconsole

srvctl stop instance -d rac -i rac1

srvctl stop instance -d rac -i rac2

srvctl stop asm -n rac1

srvctl stop asm -n rac2

srvctl stop nodeapps -n rac1

srvctl stop nodeapps -n rac2

启动RAC：

和上面的步骤正好相反即

srvctl start nodeapps -n rac1

srvctl start nodeapps -n rac2

srvctl start asm -n rac1

srvctl start asm -n rac2

srvctl start instance -d rac -i rac2

srvctl start instance -d rac -i rac1

emctl start dbconsole

milipp启停版本(10g)

$crs_stat stop/start z 启停资源

$./crs_stop -all --停止集群所有资源 或单个资源

$./crs_start -all --开启集群所有资源 或单个资源

本节点关闭crs服务 需要root用户身份

#/app/oracle/product/10.0.2.1/crs/bin/crsctl stop crs

#/etc/init.d/init.crs stop/start 启停资源

启动/停止RAC集群

确保是以 oracle UNIX 用户登录的 我们将从rac 节点运行所有命令

# su – oracle

$ hostname

Rac

停止 Oracle RAC g 环境

第一步是停止 Oracle 实例 当此实例（和相关服务）关闭后 关闭 ASM 实例 最后 关闭节点应用程序（虚拟IP GSD TNS 监听器和 ONS）

$ export ORACLE_SID=orcl

$ emctl stop dbconsole

$ srvctl stop instance d orcl i orcl

$ srvctl stop a *** n rac

$ srvctl stop nodeapps –n rac

启动 Oracle RAC g 环境

第一步是启动节点应用程序（虚拟 IP GSD TNS 监听器和 ONS） 当成功启动节点应用程序后 启动 ASM 实例 最后 启动 Oracle 实例（和相关服务）以及企业管理器数据库控制台

$ export ORACLE_SID=orcl

$ srvctl start nodeapps n rac

$ srvctl start a *** n rac

$ srvctl start instance d orcl i orcl

$ emctl start dbconsole

使用 SRVCTL 启动/停止所有实例

启动/停止所有实例及其启用的服务 我只是觉得有意思就把此步骤作为关闭所有实例的一种方法加进来了！

$ srvctl start database d orcl
