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

LSNRCTL for Linux: Version 10.2.0.1.0 - Production on 11-MAR-2012 22:09:34

srvctl操作监听，自动反馈到crs中

2.使用srvctl关闭监听

rac1-> srvctl stop listener -n rac1

rac1-> crs_stat -t

ora.rac2.ons application ONLINE ONLINE rac2

3.使用lsnrctl查看监听状态

rac1-> lsnrctl status

LSNRCTL for Linux: Version 10.2.0.1.0 - Production on 11-MAR-2012 22:15:54

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

LSNRCTL for Linux: Version 10.2.0.1.0 - Production on 11-MAR-2012 22:43:14

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

The command completed successfully

rac1-> crs_stat -t

Name Type Target State Host

------------------------------------------------------------

ora.....XFF.cs application ONLINE ONLINE rac1

ora....db1.srv application ONLINE ONLINE rac2

ora.devdb.db application ONLINE ONLINE rac2

ora....b1.inst application ONLINE ONLINE rac1

ora....b2.inst application ONLINE ONLINE rac2

ora....SM1.asm application ONLINE ONLINE rac1

ora....C1.lsnr application OFFLINE OFFLINE

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

LSNRCTL for Linux: Version 10.2.0.1.0 - Production on 11-MAR-2012 22:17:37

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

------------------------------------------------------------

ora.....XFF.cs application ONLINE ONLINE rac1

ora....db1.srv application ONLINE ONLINE rac2

ora....b1.inst application ONLINE ONLINE rac1

ora....b2.inst application ONLINE ONLINE rac2

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
