檢查RAC狀態

主節點測試各個節點rac執行是否正常。顯示rac節點詳細資訊

$ srvctl config database -d rac
Database unique name: rac
Database name: rac

$ srvctl status database -d rac
Instance rac1 is running on node rac1
Instance rac2 is running on node rac2

檢查建立的資料庫

srvctl工具可以顯示當前的RAC資料庫配置和狀態。

顯示AKA群集資料庫的配置資訊：

[email protected]> srvctl config database -d AKA

所有例項和服務的狀態：

[email protected]> srvctl status database -d AKA

某個特定節點上應用程式狀態：

[email protected]> srvctl status nodeapps -n gentic

顯示節點應用程式配置資訊（VIP，GSD，ONS，監聽器）

 [email protected]> 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.
 

群集中執行的所有例項：

sqlplus system/[email protected]
SELECT inst_id,

instance_number,

instance_name,

parallel,

status,

database_status,

active_state,

host_name host

FROM gv$instance

ORDER BY inst_id;

檢視V$ACTIVE_INSTANCES也可以顯示當前例項的狀態：

SELECT * FROM v$active_instances;

最後，GV$允許你顯示整個RAC的全域性資訊：

SELECT inst_id, username, sid, serial#

FROM gv$session

WHERE username IS NOT NULL;
