oracle集群监听启动,在RAC中lsnrctl和srvctl操作监听区别

朋友今天询问了一个问题RAC中使用srvctl 操作监听和lsnrctl 操作监听结果不一样，下面我通过实验说明问题

0.listener.ora文件内容

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 启动监听

rac1-> srvctl start listener -n rac1

rac1-> lsnrctl status

3.使用lsnrctl查看监听状态

rac1-> lsnrctl status

Copyright (c) 1991, 2005, Oracle. All rights reserved.

Connecting to (ADDRESS=(PROTOCOL=tcp)(HOST=)(PORT=1521))

TNS-12541: TNS:no listener

TNS-12560: TNS:protocol adapter error

TNS-00511: No listener

Linux Error: 111: Connection refused

rac1-> lsnrctl

LSNRCTL for Linux: Version 10.2.0.1.0 - Production on 11-MAR-2012 22:16:55

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

这里可以发现问题:

1)如果当前没有监听在运行，使用lsnrctl status的时候，会去检查默认的监听名称为listener的监听，如果该监听不存在不会使用hostname填充到hostname项中(注意下面的启动默认监听过程)

2)lsnrctl查看指定监听为listener_rac1，发现和listener.ora中配置相同

4.lsnrctl 关闭监听

rac1-> srvctl start listener -n rac1

rac1-> lsnrctl stop

rac1-> crs_stat -t

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

这里可以说明问题：

1)lsnrctl stop虽然是要停止掉默认监听，但是也会停止掉非默认监听

2)lsnrctl stop如果默认监听不存在，那么注册host也为空

5.使用lsnrctl启动默认监听

rac1-> lsnrctl start

这里发现问题：

1)监听的ip只有主机名的一个，和srvctl启动的监听不一样

2)虽然监听启动了，crs中依然显示为offline状态

6.使用lsnrctl启动listener_rac1监听

LSNRCTL> start listener_rac1

这里可以说明两个问题:

1)使用lsnrctl启动监听和srvctl启动一样

2)启动listener_rac1后，crs中监听资源变成online

7.问题原因分析

rac1-> srvctl config listener -n rac1

rac1 LISTENER_RAC1

通过这里可以发现，其实srvctl操作的监听就是LISTENER_RAC1，所以当我使用lsnrctl 操作LISTENER_RAC1监听时候crs会自动offline或者online，而lsnrctl 操作默认监听时crs不会online
