oracle+tns+01106,TNS-01106:Listener using listener name already been started
最近在做HACMP双机互备切换测试的时候，发现一个问题：
A节点的listener端口为1521 ，B节点的listener端口为1522，为什么两个节点的监听要用不同的端口号？
当时AB机使用不同端口是基于如下考虑：
HACMP的切换数据库的过程中，希望同时控制监听的启动和停止，如果两个数据库使用同一个监听，考虑如下情况
监听在A机和B都正常运行在1521
A机故障，db1切换到B机，先关闭A机的监听，文件系统切换到B机，db1在B机启动，启动监听，提示端口已被占用，可以忽略，因为A的实例会动态注册到可用的listener中去。
A机修复，db1会优先切换回A机，如果脚本中这时关闭B机监听，虽然不会影响B机已经连接的客户端，但是如果B机有新客户端连接，将不能连接到B机的数据库。
问题：为什么在一个节点上不能同时起两个同一端口的listener呢？(这个问题困惑我好久了，就连做梦都在问为什么?)
回答：其实不光是不能同时起动端口相同的listener，在listener.ora文件中，同一个KEY值的listener也是不可以同时启动的，就类似于是listener的唯一标识。即IPC addresses(KEY) or TCP port numbers are not duplicated.
在考虑这个问题的过程中，做了一些有关listener的实验，在这里与大家分享
1. 一个端口的listener可以注册多个实例
(备注：这个当然了，比如我们在一个节点上安装多个实例)

TNS-12560: TNS:protocol adapter error
TNS-00512: Address already in use
Linux Error: 98: Address already in use
Listener failed to start. See the error message(s) above...
Symptoms
There are two or more oracle instances in two seperate oracle homes. Both listeners need to run concurrently. When starting a second listener, a TNS-01106 "Listener using listener name %s has already been started" error is received.
Cause
A second listener process attempted to start with the same IPC key, port address as that of an listener already running.
Solution
Verify IPC addresses or TCP port numbers are not duplicated
#listener.ora file for the first listener
LISTENER =
(ADDRESS_LIST =
(ADDRESS= (PROTOCOL= IPC)(KEY= ORCL))
(ADDRESS= (PROTOCOL= IPC)(KEY= PNPKEY))
(ADDRESS= (PROTOCOL= TCP)(Host= jumbo)(Port= 1521))
)
#listener.ora file for the second listener
LISTENER =
(ADDRESS_LIST =
(ADDRESS= (PROTOCOL= IPC)(KEY= ORCL))
(ADDRESS= (PROTOCOL= IPC)(KEY= PNPKEY))
(ADDRESS= (PROTOCOL= TCP)(Host= jumbo)(Port= 1521))
)
The listener.ora file for the 2nd listener example must have different IPC keys from the first listener.ora file and the port number for the TCP address must be different between any other listener definitions.Implement the changes and restart the listeners
