Apache-WebLogic Bridhge Failures

Hi all, We are also having a similar setup, except that we are using WebLogic Server 5.1. We had this problem when the traffic in our production site is high. We thought we had solved the problem when we applied Service Pack 5. But after behaving for sometime if the data upload goes beyond say 5 MB the Bridge fails, but surprisingly the actual data gets uploaded. This happens when the traffic is slightly high on the site. We have set the parameter ConnectionTimeoutSecs in weblogic.conf which is called by the httpd.conf to 900. Still we are having this bridge failure problem once in a while. We are not sure what to do, is there anybody who has faced this problem and managed to solve it ? if so please SOS.Cheers,Aejaz

We don't have apache plugin for Win NT.

Apache - Weblogic Connection Issue

Hi
we are facing with Apache weblogic communication issues.
The communication with Apache and Weblogic works for some time ( few hrs), But after some time we get the below error.
Let us take one pair. (Apachedevv1 ----> Weblogicdevp1)
Yesterday evening it was working fine. Today morning I see the below error.
http://Apachedevv1/
Failure of server APACHE bridge:
No backend server available for connection: timed out after 10 seconds or idempotent set to OFF.
Build date/time: Apr 20 2009 21:26:02
Change Number: 1211636
Then I run the below command on Weblogicdevp1
C:\> telnet Apachedevv1 80
This is success as the Apache is running on Apachedevv1:80
Now If I access the URL http://Apachedevv1/ it is success now and I get the weblogic home page.
Pls let us know if you had face this type of issue earlier.
Following are the lines added in httpd.conf of Apache.
<IfModule mod_weblogic.c>
WebLogicHost Weblogicdevp1
WebLogicPort 7001
</IfModule>
<Location />
SetHandler weblogic-handler
</Location>
I see the below errors in error.log of Apache.

Thanks

The error means , there is no application server running on that port configured in apache that is 7001 at the time of issue.
One more thing you are doing telnet on 80 , but you should do telnet on 7001 and not on apache port.
So if you face the issue again, please do telnet on weblogic host like " telnet weblogicdevp1 7001".
It's not problem with apache version and weblogic plugin version.
You can integrate weblogic with apache using mod_proxy module also, pls refer the below link for more info:

Apache - weblogic connector query

I am configuring Apache 2.0 - Weblogic server 8.1 on Linux.
In this setup, Apache is the Web Server and Weblogic is the App Server. We
are using the library "mod_wl_20.so" to connect Apache and Weblogic.
Weblogic default port : 7001
Apache default port : 80
After configuring this setup, the request are getting correctly routed
through the apache server port. i.e. the URL
http://localhost:80/gepam/jsp/test.jsp gets the proper request from
weblogic.
But at the sane time , we are also able to hit the site using the weblogic
server port i.e. http://localhost:7001/gepam/jsp/test.jsp . We want to
disable this weblogic web server port.
Any clue on how to go about. Your valuable suggestion is highly appreciated.

When i access the url with out specifying port 7001 it's not working.
I checked the /var/apache/logs/error_log file. Im getting the error as

Am i missing anything here?

You may want to check the certifications for Solaris 9 and the Apache plug-in at
http://e-docs.bea.com/wls/certifications/certifications/sun_solaris9.html#40366.
It looks like you will have to upgrade to at least Apache 2.0.39. We had to do
this on Solaris 8 as well.

Let's simplify your test:

Try with just that.

That means that your apache instance is compiled with -DEAPI

Has anyone encountered problems installing Oracle 8.0.5 on Redhat 7.0. RedHat 6.2 installation works.<HR></BLOCKQUOTE>
Should be OK. I was running that combination for a while and can't recall any serious issues during install.
I am currently running 8.0.5.1 on a Mandrake 7.2 PC. The install was pretty straightforward :
- Install compatability RPMs (I used slightly higher versioned RPMs than listed in the Oracle documentation);
- Install 8.0.5.1 s/w;
- Apply Oracle patch;
- Create dbs;
- Configure listener;
- Create the startup/shutdown rc script and links.
That's about it for the installation.
I haven't put the database to much use yet, so there may be other issues ahead :)
Oh, one thing to note on that last point is that you should have a look at how the /etc/rc.d/rc file operates.
Under Mandrake 7.2 it will look for a file in /var/lock/subsystem that has the same name as the /etc/init.d script before running the stop script correctly.
This differs slightly from what I see in the *8.1.7* documentation, so might be due to a difference between mandrake and the other distributions.
FWIW here is my /etc/init.d/oracle file.
#!/bin/sh
# chkconfig: 345 99 10

Apache-Weblogic Bridge does not work?

I've gone thru' the documentation regarding setting up of apache-weblogic bridge, but still it does not work. Does anyboday have any more details regarding this...EnvironmentOS - Solars 5.7Weblogic - 5.1 SP 8Apache 1.3.12

I've given up and had to go back to running "Double NAT" which also reports as a "problem" within the AEBS, but I just "ignore" it so the light will always be green.
It still ***** though, as "Double NAT" is also a reason for "Back to my Mac" not working properly, but how the ** am I supposed to avoid Double NAT when the wireless will not work in bridged mode?!

Aborting uploads through Apache/Weblogic bridge

Hi,
I have an application to which people should be able to upload files,
however only of a certain size. So if I detect that the file is too
large (based on Content-Length), I return an errorpage and don't read
the data from the browser. This is allowed according to rfc 1867 (which,
though it is obsoleted, is the one the HTTP1.1 rfc refers to on the
matter - also the obsoleting rfc doesn't say anything on the matter) and
all browsers seems to handle this.
However, once I go through the Apache/Weblogic bridge the behaviour
changes. When the browser sends the POST request to the bridge, the
bridge relays it on to the Weblogic server and my code. I immediately
determine that the file is too large, and returns the previously
mentioned errorpage. But, the bridge doesn't stop recieving the file
from the browser until it has got the entire file and then it returns a
standard bridge POST timeout error (and the timeout has definately not
been reached).
Any ideas?

Apache-weblogic bridge problems with virtual hosting

Hi,
Can we set apache-weblogic bridge where apache webserver is configured
as virtual hosts and each Virtual Host is mapped to a WebLogic server
instance running on separate port ?
Please provide doc or reference or your comments if you have solved this
problem
Thanks
Shriniwas

The above comments notwithstanding, there's one outstanding line in your post that seems crucial:
Also if I type on my browser the name of another secondary (or virtual) domain name in the form http://domain2.com it brings the website hosted under the primary domain which is domain1.com. In case I type http://www.domain2.com than it works as it should and displays the website hosted under this domain name.
As far as Apache is concerned, 'domain2.com' and 'www.domain2.com' are completely separate entities. They have to be otherwise if all domain2.com traffic went to this site you'd never be able to host different sites within the domain (e.g. blogs.domain2.com, wiki.domain2.com, blah.domain2.com, etc.). In other words, there is no automatic relationship between a hostname and sub-records of that hostname.
So what's happening here is Apache is seeing a request for 'domain2.com' which does not match any of its configured virtual hosts, so it handles the request via the default site. If you request www.domain2.com this matches your virtual host configuration so Apache serves the alternate content.
The fix is simple - trivial, even - you just need to tell Apache all the hostnames that match this site - in this case if you've configured the site's primary address as 'www.domain2.com' and you want it to also respond to requests to 'domain2.com' then add 'domain2.com' to the list of Server Aliases in Server Admin.

If someone has already tried it and it works
can they share relevant parts of their httpd.conf.

Can you send us the lines you have added in the httpd.conf file. Also

is just a configuration problem.

There is a mod_wl_ssl.so in sp4 (i believe). mod_ssl extends Apaches API

mod_wl_ssl_rave.so because raven extends the API even further.

as worded, that sounds like a network setup problem on the apache server
side.
however, it seems that you want a server-connection-timeout error toreturn
an specific error page via the plug-in. This all depends on how theplugin
works. If it is how I think it works, there needs to be an INI
setting
to sepcify a page. Why? Because the plug-in effectively has control of
the response. It either needs a way hand control back to the web serveror
needs to have error pages of its own.
