The listener supports no services解决一例

 

Listener动态监听静态监听注册实例

今天做Advacned Replication实验的时候碰到一个问题，启动目标库监听时，出现The listener supports no services

[oracle@adrep ~]$ lsnrctl start

由于这台主机之前做的是stream实验，修改了一下hostname，之前的监听和服务名也用netca重新配置过了，但是启动监听一致是这个状态，动态监听注册不上

本地登录到Oracle实例，手动注册实例也无果，问题依旧

于是考虑通过mgr配置静态监听，但是让我郁闷的是，总是提示需要输入一个合法的SID

 

 

这个SID绝对是strmtarget没错的，global name即service name也确实是target，这个可以由以下参数获得佐证

SQL> show parameter name

 

 

NAME                                 TYPE        VALUE

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

db_file_name_convert                 string

db_name                              string      strmtarg

db_unique_name                         string      strmtarget

global_names                               boolean     TRUE

instance_name                          string      strmtarget

lock_name_space                        string

log_file_name_convert                string

processor_group_name             string

service_names                      string      target

也可以通过v$instance视图查到SID是正确的

SQL> select instance_name from v$instance;

 

INSTANCE_NAME

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

strmtarget

难道就没有办法设置静态监听了吗？NO，这里还有一种方法就是手动修改listener.ora文件，添加以下几行内容

SID_LIST_LISTENER =  

(SID_LIST =  

  (SID_DESC =  

  (GLOBAL_DBNAME = target)

  (SID_NAME = strmtarget)

  )

)

其作用就是配置一个实例静态监听，只不过用这里跳过了图形化界面修改而已，如果是用netmgr成功修改了实例的静态监听，也是会生成以上几行代码的

这里可以先把listener.ora用xftp工具拷贝出来，修改完再拷贝回相同位置即可

这里只需要重新加载一次监听就可以注册上实例了

[oracle@adrep ~]$ lsnrctl reload

这里target实例通过以上方法，成功地把实例注册上了，注意"UNKNOWN"就表示是静态注册的，如果是"READY"则表示是动态注册的

注意：动态和静态监听可以共存，如：

以上是我在zlm主机上的监听状态，可以发现，同时配置了动态和静态的监听

总结：以上利用了手动修改配置静态监听的方法成功注册了Oracle实例，动态监听往往需要等实例启动后，过一段时间才会注册上，而静态监听则 可以马上注册。而且一旦实例重启会造成动态监听暂时无效，有些版本的bug甚至会导致动态监听的注册就再也起不来了。所以我对于监听的观点是，尽量配置静 态监听，这样就可以避免很多由监听带来的问题，诸如我们经常会碰到的几个ora error：ora-12541、ora-12514、ora-12154等，尤其是在RAC和DG中，一个监听的问题，往往会带来很大的麻烦，尤其需要 引起大家的注意。
