【Oracle 集群】Linux下Oracle RAC集群搭建之基本测试与使用（九)

Oracle 11G RAC数据库安装（九）

检查RAC状态

主节点测试各个节点rac运行是否正常。显示rac节点详细信息

$ srvctl config database -d rac
Database unique name: rac
Database name: rac
Oracle home: /u01/app/oracle/product/11.2.0/db_1
Oracle user: oracle
Spfile: /u01/oradata/rac/spfilerac.ora
Domain: localdomain
Start options: open
Stop options: immediate
Database role: PRIMARY
Management policy: AUTOMATIC
Server pools: rac
Database instances: rac1,rac2
Disk Groups: 
Services: 
Database is administrator managed
$
$ srvctl status database -d rac
Instance rac1 is running on node rac1
Instance rac2 is running on node rac2
$

V$ACTIVE_INSTANCES视图还可以显示当前状态的实例。

$ sqlplus / as sysdba

检查创建的数据库

srvctl工具可以显示当前的RAC数据库配置和状态。

显示AKA群集数据库的配置信息：

oracle@RAC1> srvctl config database -d AKA

 

所有实例和服务的状态：

oracle@RAC1> srvctl status database -d AKA

 

某个特定节点上应用程序状态：

oracle@RAC1> srvctl status nodeapps -n gentic

 

显示节点应用程序配置信息（VIP，GSD，ONS，监听器）

 oracle@RAC1> srvctl config nodeapps -n gentic -a -g -s -l

VIP exists.: /gentic-vip/192.168.138.130/255.255.255.0/eth0

GSD exists.

ONS daemon exists.

Listener exists.
 

 

群集中运行的所有实例：

sqlplus system/manager@AKA1
SELECT inst_id,

instance_number,

instance_name,

parallel,

status,

database_status,

active_state,

host_name host

FROM gv$instance

ORDER BY inst_id;

 

视图V$ACTIVE_INSTANCES也可以显示当前实例的状态：

SELECT * FROM v$active_instances;

 

最后，GV$允许你显示整个RAC的全局信息：

SELECT inst_id, username, sid, serial#

FROM gv$session

WHERE username IS NOT NULL;

 

启动企业管理器控制台

企业管理控制台是整个群集共享的，在我们的例子中它在https://rac1:1158/em上监听。
