一．问题描述
一朋友在生产库的一个节点上做了一个非常危险的操作，然后该节点的数据库监听出现了异常。
数据库是2个节点的RAC，版本11.2.0.3。

--使用PS 查看监听的进程：
[grid@dave-db1 trace]$ ps -ef|grep LISTENER

注意1：
这里是有问题的，因为监听的进程出现了2次。 我们继续看。

LISTENER=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER)))) # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN1=ON # line added by Agent
二．可能原因
在MOS的文档中有说明：
Listener in INTERMEDIATE status with"Not All Endpoints Registered" [ID 1454439.1]
使用crsctl stat res -t，监听状态显示为INTERMEDIATE。
ora.LISTENER.lsnr
ONLINE ONLINE racdb1
ONLINE INTERMEDIATE racdb2 Not All Endpoints Registered
ora.LISTENER_SCAN1.lsnr
1 ONLINE INTERMEDIATE racdb2 Not All Endpoints Registered
可能的原因如下：
（1） The problem is caused byanother listener defined statically in listener.ora, using the same port and IPis running from the RDBMS ORACLE_HOME, started manually causing the defaultlistener starting from GRID_HOME can not register its endpoint. Hence the errorreported in dbca.
--在ORACLE_HOME的目录下配置了listener.ora，并且使用了相同的IP和端口。在手动的在GRID_HOME下启动默认的监听，就会导致不能注册endpoint.
ps -ef | grep tns:
grid 7222 1 0 Apr26 ? 00:00:13 /u01/app/11.2.0/grid/bin/tnslsnrLISTENER_SCAN1 -inherit
grid 7237 1 0 Apr26 ? 00:00:13 /u01/app/11.2.0/grid/bin/tnslsnrLISTENER -inherit
oracle 7354 1 0 Apr26 ? 00:00:01 /u02/app/oracle/product/11.2.0/db/bin/tnslsnrLISTENER -inherit
我们这里的情况和这里的很类似，不过我们是启动了2个grid下的监听。
(2) Another possible cause is thelistener or scan listener being defined manually in listener.ora, for example:
--另一种可能是listener 或者scan listener 被手工定义在listener.ora中.
LISTENER_SCAN3 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = racnode1)(PORT = 1523))
)
LISTENER_SCAN1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = racnode1)(PORT = 1521))
注意，这种问题只存在Oracle 11gR2 以后的版本。因为11gR2以后，Oracle 的监听配置发生了变化。 这里了解一下即可。关于11gR2 RAC监听的配置，会在单独文章说明。
From 11.2onwards, all listeners should be runing from GRID_HOME, listener andlistener_scan<n> entry should be added automatically into listener.ora,no manual editing is required for TCP definition.
--从Oracle 11gR2 之后，所有的监听都配置在GRID_HOME下，listener 和listener_scan<n> entry 会自动配置到grid 安装用户的listener.ora文件中，而不需要手工配置相关的信息。
三．解决方法
MOS文档提供的解决方法：
1. Stop the listener running from RDBMSORACLE_HOME
$<RDBMS ORACLE_HOME>/bin/lsnrctl stopLISTENER
2. stop the listener from GRID_HOME
$<GRID_HOME>/bin/srvctl stop listener-n <node name>
$<GRID_HOME>/bin/srvctl stop scan_listener -i <scan#>
eg:
$<GRID_HOME>/bin/srvctl stop listener-n racnode1
$<GRID_HOME>/bin/srvctl stop scan_listener -i 1
If above command fails to stop the tnslsnrprocess, please use "kill -9 <pid of tnslsnr>" to stop theLISTENER and LISTENER_SCAN1 process.
3. remove any manually added LISTENER definitionfrom listener.ora if it exists
4. restart the LISTENER andLISTENER_SCAN1 from GRID_HOME
$<GRID_HOME>/bin/srvctl startlistener -n <node name>
$<GRID_HOME>/bin/srvctl start scan_listener -i <scan#>
5. check crsctl stat res -t output, theyboth should show ONLINE status now.
结合前面的说明，我们这里最大的可能是重复存在的监听进程。所以我们这里只需要kill 一组监听即可。 然后监听就正常了。
这里，我们kill 掉如下2个进程：
grid 14380 1 0 2012 ? 00:02:56 /oracle/11.2.0.3/grid/bin/tnslsnr LISTENER -inherit
grid 15075 1 0 2012 ? 00:03:07 /oracle/11.2.0.3/grid/bin/tnslsnr LISTENER_SCAN1 –inherit
kill之后，监听恢复正常。
