Informix问题求教，让我很头疼！

大虾们：

   小弟一套环境：SUN Solaris 10 SPARC + Informix IDS 7.31.UD8
   Informix启动后，运行大约一天日志就开始疯狂报错，

  17:23:51  listener-thread: err = -27001: oserr = 0: errstr = : Read error occurred during connection attempt.

   17:23:52  listener: poll return with non T_LISTEN/T_DISCONNECT event

   17:23:52  listener-thread: err = -25573: oserr = 13: errstr = : Network driver cannot accept a connection on the port.System error = 13.
   17:23:53  listener: poll return with non T_LISTEN/T_DISCONNECT event

   17:23:53  listener-thread: err = -25573: oserr = 13: errstr = : Network driver cannot accept a connection on the port. System error = 13.
   17:23:54  listener: poll return with non T_LISTEN/T_DISCONNECT event

   数据库状态正常，而已经连上的应用也正常，就是无法建立新连接。连DBACCESS都连不上。

   查了一下，oserr=13是Permission Denied，在网络操作时发生Permisson Denied，请问这个问题会发生在哪里？

  帮小弟分析一下吧，非常感激！！

ROOTSIZE是否太小了点才390M

ericwong0914

ROOTSIZE目前还剩得非常多，基本够用了。

The first recommendation would be to upgrade off an old, no longer
supported version of IDS onto something more recent - like 10.00.

Presumably, you are not using new system - this is an old system that
has been working for ages.
This appears to occuring at about the time you're booting IDS - what
did you change in the Solaris environment to make it break?

If you are using a new system, why on earth did you install such an
old version of IDS?

我想你应该查以下你的操作系统方面的问题.

执行dbaccess是什么用户，是不是该用户就没有操作数据库的权限。

ONCONFIG中有两个地方可以改一下试试：
1、NETTYPE：NETTYPE tlitcp,6,70,NET，同时建议把NETTYPE ipcshm,1,100,CPU这一项注释掉。
2、BUFFER：现有的配置是不是小了一点。如果内存还有空余，这个可以加一下。
