Oracle Web Listener

[Jim Tyler_2]

Problem starting Oracle WEB Listener Error Message Follows:

Error: A failure occurred ( Permission denied ) when assigning a port ( domain: ocdev5, address: 0.0.0.0, port: 80 ).
Error: Failed to start the server.
Error: The server could not initialize
Information: The server is exiting
OWS-08811: Unable to startup Oracle Web Listener `www'.

[John Poff]

Could another server program be running already and using port 80? I'd try using 'lsof' to see if something else has that port open.

From metalink:

The oasroot.sh script needs to be run as root
from the $ORACLE_HOME/ows/4.0/install/ directory.

Hi Jim,

OWS-08811: Unable to startup Oracle Web Listener `www'.

When you got this error did you check the listener error log file, you see the following errors:
The listener error log can be found at the location: $ORAWEB_ADMIN/$ORAWEB_SITE/httpd_//.err
A required parameter, ServerPID, specified in the listener configuration file is missing or has become corrupted. This parameter provides the full path of the file to which the WAS listener will write its process id (PID) when it starts up. The current value for this parameter can be viewed using the OAS node manager to select HTTP listeners->myhost:WWW->Network in the tree applet. The value for the ServerPID parameter is displayed in the field labeled Listener PID file. This value can also be accessed and modified using a standard UNIX text editor such as VI or EMACS. Since the format of this file is highly sensitive it is recommended that you make a backup copy prior to making modifications.
During startup, OAS needs to write to a file where it stores the process IDs for active listener processes and failure to obtain the correct location of this file prevents an OAS listener from starting. This note supplies a manual procedure for supplying the parameter that is missing from the listener configuration file, thereby allowing the OAS listener to start.

Try running oasroot.sh.

Metalink tells the files inside

$ORACLE_HOME/ows/4.0/bin
should have root permissions.

-rwsr-sr-x 1 root other 16028 Okt 5 1998 apchlctl

-rwsr-sr-x 1 root dba 1911756 Nov 4 1998 oraweb

My experience is with Weblogic webserver, Tuxedo application server, and Oracle database. We have had similar issues with the web server not starting because of another process (thus far always the Work Station Handler from the application server) that is hogging the port. (Use "ps -ef" and grep for the port number - in your case 80 - to identify what is using that port.)

Even after shutting down the app server, the WSH process still remains active so I have had to kill it. Then restarting the app server and webserver works fine.

Good luck!

Oracle web listener is really apache.

without running the oasroot.sh script it will never run because root permissions are required for any port below 1024

Could this however be more basic?

If its not oasroot.sh could it be a problem with httpd.conf?

Lets say you have a named web server Servername schmobagel.com

and schmobagel.com doesn't resolve.

Or you have an IP based name and you don't have that IP addressed configured in /etc/rc.config.d/netconf


Check that your basic networking is working and matches httpd.conf

I like the oasroot.sh solution but I'd think a better error message would include the IP address of the HP server.

Here is what metalink has to say about the error.

okay, I was probably wrong about apache. It was first used for Internet Applicataion Server 1.0

Have you applied any patches recently. The oracle forums show at least three users having this error after applying oracle patches.
