1.3 语法简汇
1.3.1 数据库与实例
srvctl config database # 列出安装的数据库
srvctl config database -d rac -a # 检查数据库相关的信息
srvctlstatus database -d RAC # 检查数据库的状态
srvctl status instance -d RAC -i rac1 # 检查指定实例的状态


srvctl config asm -a # ASM配置
srvctl status asm # ASM的状态


srvctl start database -d rac # 启动数据库
srvctl stop database -d rac # 关闭数据库


srvctl start instance -d rac -i rac1 # 启动指定的实例
srvctl stop instance -d rac -i rac2 # 关闭指定实例
 
1.3.2 网络相关的命令
 
srvctl status listener # 检查TNS listener的状态
srvctl config scan # SCAN的配置
srvctl status scan # SCAN listener状态, 包含当前运行节点的信息


# 检查VIP的配置及状态
srvctl status vip -n rac1
srvctl config vip -n rac1
 
1.3.3 查看各资源状态(nodeapps节点应用程序，ASM实例，数据库等)

在11g R2中，默认 oc4j和gsd资源是 disable的；oc4j 是用于WLM 的一个资源, WLM在 11.2.0.2 才可用；gsd是 CRS 用于跟 9i RAC 进行通信的一个模块,是为了向后兼容才保留的，不影响性能；建议不要刪除, 也不要尝试开启他们, 忽略即可。
 
ora.gsd is OFFLINE by default ifthere is no 9i database in the cluster.
ora.oc4j is OFFLINE in 11.2.0.1 as DatabaseWorkload Management(DBWLM) is unavailable. these can be ignored in11gR2 RAC.
 
状态检查也可以使用如下命令：
crsctl stat resource –t
或者
crsctl stat resource

1.3.4 综合
1、通过SRVCTL命令来start/stop/check所有的实例:
srvctl start|stop|status database -d
 
2、start/stop指定的实例：
srvctl start|stop|statusinstance -d -i
 
3、列出当前RAC下所有的
srvctl config database -d
 
4、start/stop/check 所有的nodeapps，比如：VIP, GSD, listener, ONS：
srvctl start|stop|status nodeapps -n
 
5、如果你使用ASM，srvctl也可以start/stop ASM实例：
srvctl start|stop asm -n [-i ] [-o]
 
6、可以获取所有的环境信息：
srvctl getenv database -d [-i]
 
7、设置全局环境和变量：
srvctl setenv database -d -t
 
8、从OCR中删除已有的数据库：
srvctl remove database -d
 
9、向OCR中添加一个数据库的实例：
srvctl add instance -d -i -n
srvctl add instance -d -i -n
