ERROR: ORA-12541: TNS:no listener

使用pl/sql连接远程Linux上的oracle出现ERROR: ORA-12541: TNS:no listener
本人用的是win系统,想使用pl/sql连接远程oracle,配置文件都配了,实在是没有办法了,求大神救救我

4个回答

更改listener.ora里面的内容
把listener.ora的内容:

listener.ora Network Configuration File: D:\oracle\product\10.2.0\db_1\network\admin\listener.ora

Generated by Oracle configuration tools.

SID_LIST_LI......
答案就在这里:ORA-12541:TNS:no listener
----------------------Hi,地球人,我是问答机器人小S,上面的内容就是我狂拽酷炫叼炸天的答案,除了赞同,你还有别的选择吗?

肯定是配置文件写错了。你先下一个Oracle官方的SQL Developer试试看,那里的连接配置比较简单易用。

DreamDemo 我用navicat for oracle 远程连接服务器上的oracle可以成功,服务器上的系统是linux。用pl/sql就是不行,一直说没有监听,网上都说是本机客户端的配置文件有问题,求帮忙
4 年多之前 回复

已经解决了,在环境变量里多加了一个分号

ok,也应该是配置问题

docker中启动Oracle,第一次可以连接,重启docker后连不上oracle

ORA-04030:在尝试分配8192字节(sort subheap,sort key)时进程内存不足

先来描述一下我的环境吧:window 32bit, oracle9i,session和process的数量在正常时100左右,OS内存以前是2G,现在加到了8G,系统在4月1号之前已经正常运行2年之久,没出过啥大问题,从4月1日愚人节开始,每天必down。 alert日志中见到最多的就是ORA-04030错误,而且一般伴随着 skgpspawn failed:category = 27143, depinfo = 9261, op = spdcr, loc = skgpspawn 信息 在出问题的时段监听日志listener.log: TNS-12560: TNS: 协议适配器错误 TNS-00530: 协议适配器错误 32-bit Windows Error: 54: Unknown error TNS-12500: TNS:监听器未能启动专用的服务器进程 TNS-12540: TNS:超出内部极限限制 TNS-12560: TNS: 协议适配器错误 TNS-00510: 超出内部极限限制 32-bit Windows Error: 8: Exec format error 在外面的表现来看,就是将要出问题之前,新的连接进不去,但已建立的连接可以继续操作,但也只能做小数据量查询。网上查的资料都说是系统资源不足,特别是内存,后来内存从2G加到8G,对应也调整了PGA和SGA大小,但问题依然出现,每个4-5小时就出现PL/SQL连接不进去: ORA-04030: out of process memory when trying to allocate 33292 bytes (pga heap,…… 每次只需要重启windows上的oracle实例服务就好了。后来通过process explorer线程查看工具偶然发现,每4-5个小时的时间内,ORACLE.EXE进程下的线程从100一直网上涨,大概到980左右就挂了,然而在SQL里查出来的线程(包括后台进程)一直都是比较正常的数值100左右,不知道操作系统哪里还有oracle的资源没有释放,也统计了oracle即将出问题的时候(oralce.exe进程内存从200M涨到最高值580M),这些看起来比较正常的100来个sessiond的PGA/SGA占用,都比较正常。 不知道是否有人遇到过类似的问题,因为应用是买的,所以从32位改成64位需要重新部署引用,实施费用公司肯定是不同意的。正考虑从9i升级到10g,但依然没有把握。究竟是什么问题呢?
