ORACLE WebDB Listener error
I have an HP9000 T520 with HPUX 11.0 running an application that had an ORACLE DB (ver 8.1.6) and an ORACLE WebDB (ver 2.2.0.0.8) running. From time to time, the Web Listener (on port 80) goes down. The listener log shows these two errors: "Attempting to Listen - Fatal Error - Poll failed (errno 0)" and "Attempting to Listen - Fatal Error - Accept failed (errno 233)".
I have had to stop and start the listener process to get it up listening again.
Does anyone have a clue as to why these error messages are generated? Could it be a kernel parameter that needs to be adjusted? A needed Patch? A network problem?
Thanks in advance for your assistance!
Connie

Re: ORACLE WebDB Listener error
Seems like your system is running out of Buffer Space. The error no 233 refers to ENOBUFS -> No Buffer Space Available
quote //
1. ) No buffer space is available. The accept() cannot complete. The queued socket connect request is aborted.
2.) No buffer space is available. The bind() cannot complete.
3.)No buffer space available. An operation on a socket was not performed because the system lacked sufficient buffer space.
// Endquote
Hope this helps.
Thanks

Re: ORACLE WebDB Listener error
I have NOT yet solved this problem, but at least Sanjay gave me a heading. I have asked the DBA to get guidance from our Oracle Support Office. I believe the problem is related to some of the kernel parameters and I assume that somewhere there is a list of recommended kernel parm settings for this configuration of the WebDB.
Thanks Again.

Re: ORACLE WebDB Listener error
Here is a script we use to monitor the WebDB listener and restart if necessary. Change the email address if you want to receive notifications on your pager/cellphone.
