我的processes = 500，而且，哪那么多客户端
好象要在tnsnams.ora设置一个dedicated 参数，查查文档吧.
而且，早先没有这个问题，这是最近出的，一般运行几天后才出现这个问题
再不行，就将tnslistener服务停掉重启动（记住，不是stop/start，而是重起服务）

你的SGA大约使用了400M的内存sort_area_size大约是640k（这是每个session所用的）请检测这样几个问题：
1：你的机器的内存是多少？ 1G?
2: 当出现这种问题的时候 connect system/manager 这样还能登陆上数据库么？如果这样也不能登陆则说明不是 listener的问题，如果这样能登陆但connect system/manager@net_service_name 不能登陆，才说明是网络或者listener的问题
3：system用户：select count(*) from v$session;看有多少会话在数据库中，是不是有很多？到底多少？
综合各种因素再确信问题所在
看样子我还是交代的不够详细。
我的数据库是在hp 6000上，NT操作系统，1G内存，RAID5的磁盘阵列
在本机通过connect system/manager能登录
但在客户端就不可以，客户端以前的连接照旧能用，只是不能在开新的连接。
select * from v$session的记录不超过50。远远没有达到init文件中的
processes值
还有，我的机器是双网卡，以上的监听在拷贝的时候有点失误，有一部分是这样。
LISTENER =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.40.5.117)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.61.181)(PORT = 1521))
(ADDRESS = (PROTOCOL = NMP)(SERVER = NETSERVER)(PIPE = ORAPIPE))
)
我检查了一下以上资料，其他的都是正确的。
因为我的机器要在两个网段中使用。
-----------------------------------------
我奇怪的是，我重起监听器都不可以，非要重起数据库或机器
要么，我只好配置成多线程，或是不用预分配的专用服务器。
如果要重起数据库很麻烦的，我想找出原因所在，我不可能天天看着数据库的。
不同网段使用同一个数据库，没有理由要两个ip,listenr中host就一个ip就可以了在本机上走 listener能登陆么？
connect system/manager@net_service_name
如果本机也能登陆，那就是listener的配置和网卡有地方出问题
导致client无法访问client : tnsping net_service_name , 正常么？最后，使用一块网卡，重新配置listener，试一下
POOL_SIZE = 2 是预分配专用服务器进程自动配置的，它只是一个监听池，而且好象是必须的。会与它有关吗？不过我可以试试。
这个错误已经有好几天又没有出了。我正在等它重出呢。
本机connect system/manager@net_service_name也不能连接的。
client : tnsping net_service_name的我没有试，现在不出错了，我还没有环境，我得等下一次错误才能试。
我也认为这个错误最大的可能就是监听错误，不是监听的ip出的问题，而是预分配专用进程的问题，再出错的话，我就改回普通的专用进程的分配，不用预分配专用进程。

你只要用预分配专用进程分配
POOL_SIZE = 2是不能去掉的，只能是改变大小，这是预分配专用进程的cache池。否则的话，你连监听器启动都会出错。
我早说过，你还是不用这种方式算了，有很多错误，连oracle自己的维护人员都有可能解决不了，也有很多是oracle的bug(如00600错误）
我们只能是这样，如果有错误的可能，只要改变一种方式，能避免这种错误，也是一种成功，不要在一棵树上吊死。
以上只是我个人的观点，大家可以不必赞同。
但我最烦的是oracle的这么一句话
contact Worldwide Customer Support
谁有机会去找他，他以为人人都用的是有许可的呀。
所以，象oracle的这种错误，我能避开的就避开
不是一定需要双网卡的
在listener上使用任意一个名字
内部网的client能把该名字解析成内部ip （在hosts中设置）
在外部网上的client把该名字解析成外部ip（在hosts中设置）
这样就可以了因为以前我就遇见过这样的内网外网的我问题问题（hosts在unix下我就不说了，windows下是C:\WINNT\system32\drivers\etc\hosts）
我以前也遇见过外网内网的问题
在listener中host设置成一个随意的名字，假定 eee
然后在内网的client上把eee解析成内网ip
外网上把eee解析成外网ip
本机上eee当然也解析成本机地址
就这样就可以解决这个问题unix下我就不说了
windows下是在下面文件中修改C:\WINNT\system32\drivers\etc\hosts
就我的观点来说，我觉得bachelor(鹰飞九月) 的配置法还是可取的，如果照你的办法来，那不是每个client都得修改host文件（当然配置dns服务器也可以）。
我觉得，client的工作还是越简单越好。
