【Oracle 集羣】Linux下Oracle RAC集羣搭建之基本測試與使用（九)

Oracle 11G RAC數據庫安裝（九）

檢查RAC狀態

主節點測試各個節點rac運行是否正常。顯示rac節點詳細信息

$ 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視圖還可以顯示當前狀態的實例。

$ sqlplus / as sysdba

檢查創建的數據庫

srvctl工具可以顯示當前的RAC數據庫配置和狀態。

顯示AKA羣集數據庫的配置信息：

oracle@RAC1> srvctl config database -d AKA

 

所有實例和服務的狀態：

oracle@RAC1> srvctl status database -d AKA

 

某個特定節點上應用程序狀態：

oracle@RAC1> srvctl status nodeapps -n gentic

 

顯示節點應用程序配置信息（VIP，GSD，ONS，監聽器）

 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.
 

 

羣集中運行的所有實例：

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;

 

視圖V$ACTIVE_INSTANCES也可以顯示當前實例的狀態：

SELECT * FROM v$active_instances;

 

最後，GV$允許你顯示整個RAC的全局信息：

SELECT inst_id, username, sid, serial#

FROM gv$session

WHERE username IS NOT NULL;

 

啓動企業管理器控制檯

企業管理控制檯是整個羣集共享的，在我們的例子中它在https://rac1:1158/em上監聽。
