Informix Error 25573
a connection on the port -25573 oserr 233 Network driver connection port listen queue depth Technote (troubleshooting) Problem(Abstract) This article describes a possible resolution for connectivity problems by tuning the "Listen Queue depth" network configuration parameter. Resolving the problem PROBLEM You experience dropped connections and listener thread errors -25573 and oserr = 233, or "Network driver cannot accept a connection on the port". Another error frequently reported is listener-thread: err = -25580: oserr = 0: errstr = : System error occurred in network function. SCOPE This document applies to systems that implement the TCP/IP Internet protocol for database connectivity. CAUSE These errors can be an indication of a low configuration setting for the TCP "listen queue". Important: This is only one possible cause of the problem. If this document does not provide you with a solution to your problem, you should search for other documents that refer to this topic. SOLUTION The operating system configuration parameter to set for the listen queue is platform dependent. Example: Solaris : tcp_conn_req_max_q HP : tcp_conn_request_max Steps to check and change the listen queue settings: 1. Confirm that the connections are being dropped. Run the command: netstat -s Look for any connections requests dropped due to full queue. 2. If the number of connections dropped is greater than 0, use the ndd command to check the current settings. Example: Solaris : ndd –get /dev/tcp tcp_conn_req_max_q HP : ndd -get /dev/tcp tcp_conn_request_max 3. Use the ndd command with the -set option to adjust the operating system listen queue. Example: To set the listen queue size to 256 Solaris : ndd -set /dev/tcp tcp_conn_req_max_q 256 HP : ndd -set /dev/tcp tcp_conn_request_max 256 Document information More support for: Informix Servers Software version: 7.3, 9.4, 10.0, 11.1, 11.5 Operating system(s): HP-UX, Solaris Reference #: 1207733 Modified date: 2005-05-27 Site availability Site assistance Contact and feedback Need support?

having problems connecting to IDS 11.5 on my Vista Business SP1 machine. I downloaded the developers evaluation from the IIUG and installed it (selecting to run it under user informix rather than a system account). http://www.yqcomputer.com/246_193_1.htm I think I took all the defaults (including no to role separation). The default instance (called "vaio") runs (though I've got a further question about that for later) OK and I can run dbaccess and also connect to it using ODBC on the local machine and the ilogin demo works as well from the local machine. The entry in the services file is infx_vaio 9088/tcp However I can't connect to it from another machine informix error on the network and I'm getting the following message in vaio.log Informix error -25573 Network driver cannot accept a connection on the port I've searched for more info but can't find anything so I throw myself on your mercy. Any ideas gratefully received. Thanks in advance Richard Top Informix error -25573 Network Driver cannot accept a connection on the port by Richard M » Tue, 18 Nov 2008 22:42:55 Hi informix error 25573 Fernando, thanks for replying. I don't get any system error numbers. Yes the port is flagged as LISTENING. I have a McAfee firewall which is configure to allow 9088 through and I have turned it off altogether as well, the Vista Firewall is off. Of course that doesn't mean it isn't a problem with the firewall as I can't be sure it's not interfering in some way as the Windows security centre thinks the McAfee firewall is still running. The McAfee firewall also block programs that make outgoing calls to ports but it does prompt you and allows you to select block or allow. I've allowed everything. Someone else suggested I turn of User Access Control which I have done for the informix user and also the regular user I run dbaccess/server studio under. However it didn't make any difference. I'll try uninstalling McAfee. All the best, R Top Informix error -25573 Network Driver cannot accept a connection on the port by Richard M » Wed, 19 Nov 2008 00:30:01 Just to say that I've uninstalled the McAfee firewall and disable Windows firewall but no change, still getting error and still cannot connect.
