朋友今天詢問了一個問題RAC中使用srvctl 操作監聽和lsnrctl 操作監聽結果不一樣，下面我通過實驗說明問題

0.listener.ora文件內容

LISTENER_RAC1 =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = rac1-vip)(PORT = 1521)(IP = FIRST))

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.11)(PORT = 1521)(IP = FIRST))

)

)

SID_LIST_LISTENER_RAC1 =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)

(PROGRAM = extproc)

)

)

1.srvctl 啟動監聽

rac1-> srvctl start listener -n rac1

rac1-> lsnrctl status

3.使用lsnrctl查看監聽狀態

rac1-> lsnrctl status

TNS-12541: TNS:no listener

TNS-12560: TNS:protocol adapter error

TNS-00511: No listener

Linux Error: 111: Connection refused

rac1-> lsnrctl

Welcome to LSNRCTL, type "help" for information.

LSNRCTL> status listener_rac1

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=rac1-vip)(PORT=1521)(IP=FIRST)))

TNS-12541: TNS:no listener

TNS-12560: TNS:protocol adapter error

TNS-00511: No listener

Linux Error: 111: Connection refused

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.1.11)(PORT=1521)(IP=FIRST)))

TNS-12541: TNS:no listener

TNS-12560: TNS:protocol adapter error

TNS-00511: No listener

Linux Error: 111: Connection refused

這里可以發現問題:

1)如果當前沒有監聽在運行，使用lsnrctl status的時候，會去檢查默認的監聽名稱為listener的監聽，如果該監聽不存在不會使用hostname填充到hostname項中(注意下面的啟動默認監聽過程)

2)lsnrctl查看指定監聽為listener_rac1，發現和listener.ora中配置相同

4.lsnrctl 關閉監聽

rac1-> srvctl start listener -n rac1

rac1-> lsnrctl stop

ora....C2.lsnr application ONLINE ONLINE rac2

ora.rac2.gsd application ONLINE ONLINE rac2

ora.rac2.ons application ONLINE ONLINE rac2

ora.rac2.vip application ONLINE ONLINE rac2

這里可以說明問題：

1)lsnrctl stop雖然是要停止掉默認監聽，但是也會停止掉非默認監聽

2)lsnrctl stop如果默認監聽不存在，那么注冊host也為空

5.使用lsnrctl啟動默認監聽

rac1-> lsnrctl start

這里發現問題：

1)監聽的ip只有主機名的一個，和srvctl啟動的監聽不一樣

2)雖然監聽啟動了，crs中依然顯示為offline狀態

6.使用lsnrctl啟動listener_rac1監聽

LSNRCTL> start listener_rac1

ora.rac2.ons application ONLINE ONLINE rac2

ora.rac2.vip application ONLINE ONLINE rac2

這里可以說明兩個問題:

1)使用lsnrctl啟動監聽和srvctl啟動一樣

2)啟動listener_rac1后，crs中監聽資源變成online

7.問題原因分析

rac1-> srvctl config listener -n rac1

rac1 LISTENER_RAC1

通過這里可以發現，其實srvctl操作的監聽就是LISTENER_RAC1，所以當我使用lsnrctl 操作LISTENER_RAC1監聽時候crs會自動offline或者online，而lsnrctl 操作默認監聽時crs不會online
