Apache plug in problems

Hi!
I tried to use apache plug-in to forward request to a wls6.1sp2. So I installed
mod_wl.so and added the following lines to my httpd.conf:
LoadModule weblogic_module libexec/mod_wl.so
<IfModule mod_weblogic.c>
WebLogicHost reg.sonyssi-dev.com
WebLogicPort 7501
Debug ON
DebugConfigInfo ON
</IfModule>
<Location /dime/ero> SetHandler weblogic-handler </Location>
When I start apache it forwards my requests to weblogic but with the wrong port.
When I try to call my webapp it always forwards via port 80 (with https port 443)
instead of port 7501!?
Has anyone expereinced a similiar problem?
Thanks, Chris

I believe I have solved this issue.
a) The error message below is BEA code for "enable DEBUG in the proxy and look
in the debug file".
b) The 128 bit version of the plug-in appears to do a wider variety of validations,
in my case complaining about a lack of basic constraints on the CA certificate.
IMHO: Better error handling would improve things by an order of magnitude.

I am using SSL and the following plug-in config and was using the export
version
(non 128 bit) of the the Apache 2 plug-in.
<IfModule mod_weblogic.c>
WebLogicHost localhost
WebLogicPort 7002
RequireSSLHostMatch false
WLProxySSL ON
SecureProxy ON
TrustedCAFile c:/bea/wlserver6.1/config/devdomain/ca.pem
RequireSSLHostMatch false
PathPrepend /csmain-web
ErrorPage /err/serverErrorWL.xml
</IfModule>
However, when I move to the 128 bit version of the plug-in (with the
same cert/key
on the server as before) I get the following in my Apache error.log.
Error is: [Wed Aug 13 09:25:32 2003] [error] WRITE_ERROR_TO_SERVER [os
error=0,
line 720 of ../nsapi/URL.cpp]:
From previous posts it looks this is code for "didn't like some aspect
of the
details given to me during SSL protocol negotiation with the WebLogic
server".
Can someone give me some clues or explain to me the differences between
the 128
bit version of the plug-in and the export version that would result in
this issue?
Any ideas gratefully received.
Thanks,
Andy Schneider.

Apache Plug-In: PathPrepend doesn't work?

Hello All,
I've run into a problem at a customer site with the WLS 5.1 Apache Plug-In
with Apache 1.3.12 on Solaris 6: the PathTrim parameter does not work.
Could somebody look at my httpd.conf file and tell me what I'm doing wrong:
<Location /weblogic>
SetHandler weblogic-handler
</Location>
WebLogicHost ism-app
WebLogicPort 7010
PathTrim weblogic
DebugConfigInfo ON
That's as basic as it gets, but it doesn't work! The url
/weblogic/index.html should get sent to wls as /index.html; instead, it's
sent verbatim.
I've tried the plug-in from service pack versions 3, 4, 6, and 8, and tried
the PathPrepend parameter inside the Location tag as well as outside. I
can't imagine that this does not work for any plug-in in any service pack;
if this is a bug in all these service packs, we really need to take a
serious look at QA.

Hi,
the "apex.widget.initPageItem" will not help you in your case, it's used to register callbacks for $s, $v, show, hide, ... if you have a more advanced item type. You can have a look at the "Star Rating" plug-in which implements several of these callbacks.
For adding cascading LOV support, please have a look at our own select list implementation in /i/javascript/uncompressed/apex_widget_4_0.js
Search for
apex.widget.selectList = function(pSelector, pOptions) {to get a blue print implementation for all the steps you have to add to your widget to add cascading LOV support.
If you need further help, please let me know.

Apache plug-in won't load balance requests evenly on cluster

I can't seem to get the Apache plug-in to actually do round-robin load balancing
of HTTP
requests. It does random-robin, as I like to call it, since the plug-in will usually
hit all the
servers in the cluster but in a random fashion.
I've got three managed servers:
192.168.1.5:8001 (WL6 on Linux) 192.168.1.2:8001 (WL6 on Linux) 192.168.1.7:8001
(WL6 on Linux)
Admin server on 192.168.1.7:7000 (WL6 on W2k)
My Apache server is 1.3.9 (RedHat SSL) on 192.168.1.52.
The log file for each servers has something like this:
####<Apr 19, 2001 1:18:54 AM MDT> <Info> <Cluster> <neptune> <cluster1server1>
<main> <system> <> <000102> <Joined cluster cluster1 at address 225.0.0.5 on port

to the cluster> ####<Apr 19, 2001 1:19:31 AM MDT> <Info> <Cluster> <neptune>

to the cluster>
So I believe I have correctly created a cluster, although I did not bother to
assign
replication groups for HTTP session replication (yet).
The Apache debug output indicates it knows about all three servers and I can see
it
doing the "random-robin" load balancing. Here is the output:

Right - it means that the only configuration which can do perfect round-robin is a
single plugin (non-Apache, or single-process Apache) - all others essentially do random
(sort of, but it can skew test results during first N requests).
Robert Patrick <[email protected]> wrote:
Dimitri,
The way Apache works is that is spawns a bunch of child processes and the parent process
that listens on the port delegates the processing of each request to one of the child
processes. This means that the load-balancing dome by the plugin before the session ID is
assigned does not do perfect round-robining because there are multiple copies of the plugin
loaded in the multiple child processes. This situation is similar to the one you would get
by running multiple proxy servers on different machines with the NES/iPlanet and IIS
plugins.
As I pointed out in my response to Jeff, attempting to address this problem with IPC
machanisms would only solve the single machine problem and most people deploy multiple
proxy servers to avoid a single point of failure...
Hope this helps,
Robert

Hrm. This is strange - I thought that all the information nesessary for a
'sticky' load-balancing (primary/secondary) is contained in the cookie/session info,
so, the particular plug-in implementation should not make any difference. For
load-balancing - statistically, given large enough sampling base, Apache plug-in
should perform just a well as NS one (unless apache is somehow misconfigured and
calls fork() for each new request).

Thanks for the sanity reply, you are definitely right. I used Netscape 3.0 on

In some tests, as many as 90% of my connections/requests would be sent to a single
server. There should be something in the release notes like "By the way, the
Apache plug-in is only advertised as doing round-robin load balancing, in reality
it doesn't work worth a darn".
I'm surprised they don't used shared memory or some other technique (pipes, sockets,
signals, writing to /tmp, anything) for interprocess communication to fix that.

Yes, the problem lies in the fact that Apache uses multiple processes

Hopefully, Apache 2.0 when it comes out will allow the plugin to do a
better job...

Compile Apache plug-in for WL7.1 SP4

Hi all,
Several advisories of Apache have been published. We would like to acquire the latest Apache version. According to the information of BEA. Apache plug-in of WL71SP4 is only provided for Apache 2.0.42-2.0.49. As a result, a new plug-in is needed: we would like to compile one.
We only have compiled Apache plug-in (with WL71SP4). We cannot find the source in WL71SP4.
Does anyone know how can I compile a Apache plug-in for the latest Apache version? Preferably, we would like to use APXS for the compilation.
Does anyone know if we can use the existing plug-in in latest Apache version? We have encountered problems before -- the plug-in refuses to start and complains about incorrect magic string of the Apache version.
Thank you very much.
Regards.

I'm using the mod_wl_ssl.so for Apache on Linux from service pack 5. I
          understand that the communication from Apache to WLS will be via http...
          that's not the issue.
          I think what would solve the issue would be if someone from BEA could post
          an httpd.conf file that was configured correctly to use the ssl proxy for
          Apach on Linux. Also, I can't seem to get clarification if openssl is or is
          not supported.
          Can you post a correctly configured httpd.conf file that was used in testing
          the ssl proxy as well as confirm whether or not openssl is supported???

Question with using ssl of apache plug-in

hi all,
I use redhat 6.0,apache 1.3.19, wls6.0sp1.
how can I proxy a ssl request from apache to wls?
can someone give example conf files(httpd.conf,weblogic.conf)?
Thanks.
Kent

Yes the weserver could help in taking some load off weblogic. In case of
upload
the connection from WebLogic is not initiated until all the POST data is
read from the
client. So if the client connection is slow WebLogic will not be affected.
Similarly
after reading the response data from weblogic, plugins close the connetion
with
WebLogic. So worth a try.

Hi,
We have an application (JSP, EJB) running on WLS 5.1sp6, and we're
experiencing load issues. In the past, I've been able to get much higher
performance out of weblogic (at one point we were maxing the server, anE450
with 3cpu, 3GB memory) with 100 users. In the meantime, we've identified
problem areas (db, solaris tuning, etc.). I'm wondering what kind of
performance gain we might see using the apache plug-in.
Obviously, having apache serve up static content will free up weblogic to
handle the requests for dynamic content.
What I'd really like to know is how does the apache plug-in actuallyhandle
requests/responses. We have a number of users who connect directly to our
network by modem, and I'm thinking that they may be hogging resources. AmI
correct in assuming that if the modem user needs 20 seconds to download40k
of data from our server, that his connection to weblogic will be activefor
the 20 seconds? If so, would adding the apache bridge help? If apache
maintains a connection to weblogic during the entire download, servingonly
as a passthrough, I imagine it wouldn't help a lot. However, if Apache
makes the request, and buffers the response, such an approach would freeup
weblogic threads to handle other requests while busies itself with the
delivery of data to the slow client.
Please help me out on this one (and thanks in advance).

WLS 7.0SP2 Apache Plug-in application fault

I'm running WLS 7.0SP2 on XP and have the WLS Apache plug-in in Apache 2.0.49.
I get this application fault alot...
Faulting application apache.exe, version 2.0.49.0, faulting module unknown, version
0.0.0.0, fault address 0x008be6ae.
The only other non-default module I'm using mod_headers.
I have the same problem in Apache 2.0.45, 2.0.46, 2.0.47, 2.0.48, and 2.0.49
Has anyone else run across this problem? I'd REALLY like to know the root cause..
Thanks,

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
For this step, the title of the Console window should be All Messages. If it isn't, select
          SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar at the top of the screen.
In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter the name of the crashed application or process. For example, if iTunes crashed, you would enter "iTunes" (without the quotes.)
Each message in the log begins with the date and time when it was entered. Select the messages from the time of the last crash, if any. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
☞ The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
☞ Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ User Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of crash reports. The name of each report starts with the name of the process, and ends with ".crash". Select the most recent report related to the process in question. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
If you don't see any reports listed, but you know there was a crash, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report—they're very long and rarely helpful.

Glibc-2.9.2-i686 breaks apache and causes problems with samba?

I could not start the apache daemon. The output from /usr/sbin/apachectl start is
httpd: ../sysdeps/posix/getaddrinfo.c:1465: rfc3484_sort: Assertion `src->results[i].native == -1 || src->results[i].native == a2_native' failed.
/usr/sbin/apachectl: line 78: 2933 Aborted $HTTPD -k $ARGV
The getaddrinfo.c, I believe, is in the glibc package.
Also, I get error logs in my /var/log/samba directory named like "__ffff" followed by the IP address of a remote client. In one of them it says that samba is dumping core and contains

I downgraded glibc to 2.8-3 and I can now start apache. No problems with samba yet either although I had to make pacman skip dependency checks because a number of packages depended on glibc >= 2.9.

getaddrinfo.c - this is place where glibc 2.9 has a major change in IP resolving. see the bugreport we had and still have. search google and upstream (Fedora/RedHat) for reports.
maybe a simple recompile of the affected packages can help. holding an outdated version is a bad solution. new packages compiled against the new version may use new functions and break with the old one.

Apache Plug-in wont re-direct.

I'm trying to use the apache plug-in to redirect traffic to my non-clusterd weblogic server but I can not get it to work. I'm trying to route everything to Weblogic. It loads the weblogic plugin but I never get re-routed. Any help is appreciated.
Thanks,
Tom.

OK, I chmod 777 to the mod_wl_20.so.
I also changed the httpd.config to:
<IfModule mod_weblogic.c>
WebLogicHost lwpvcma1.lc.ca.gov
WebLogicPort 9001
WLLocalIP "my local ip - removed for security"

DebugConfigInfo ON

SetHandler weblogic-handler
PathTrim /ShoppingCart

But I still get the same result. The apache server and weblogic server are running on the same machine - not sure if that makes a difference.

WLS 8.1 Apache Plug-in is changing HTTP status code 999 to 500

I'm seeing the weblogic server 8.1 sp4 apache plug-in change the HTTP status code of 999 (set by the application) to 500 Internal Server Error. I'm seeing this with Apache 2.0.48 on aix and with Apache 2.0.58 on windows. I've tried the plug-in from 8.1 SP2, SP4 and SP6 with all yielding the same result. I've tried the SSL plug-in too - same result. I'm told by the maker of this application that they are not seeing this issue with the plug-in for SunOne/NES. What does BEA say about the Apache plug-in changing the http status code? Why is it doing this? Why doesn't the SunOne/NES plug-in do it? Can you provide a plug-in that does not do this?

Try setting
Debug ALL
inside your IfModule. All proxy activity will be written to /tmp/wlproxy.log (on
unixes). If no info appears in the log, Apache is not invoking the plug-in properly.

My test web application runs on

and
192.168.10.142:6001/public/testwebapp
I have tested my cluster using another instance on WLS and HttpClusterServlet
and it works fine.
I have added following section to my httpd.conf
LoadModule weblogic_module modules/mod_wl_20.so

I restarted my wls cluster and apache as well and when I specify http://192.168.10.142/public/testwebapp
(apache web server) I receive Error 404--Not Found (even thou I have
tested my
http://192.168.10.142:5001/public/testwebapp and http://192.168.10.142:6001/public/testwebapp
- they work correctly).
There is nothing in apache’s error_log file.
There is a record in access_log file reading:
192.168.10.126 - - [08/Jun/2004:16:23:32 -0700] "GET /public/testwebapp
HTTP/1.1"
404 1214
which gives me an impression that “proxy” – forwarding does not work.
Where should I look for some errors?

Apache plug-in prob : when trying to access '/weblogic/' URL , "404 : file not found" error is shown

On : Apache 2.0 , Weblogic 7.0, Win 2000
I installed the Apache plug-in for as described in WL docs, but when I try to
access a URL /weblogic/ ( supposed to be configured automatically ) on apache,
I get '404 : file not found' error.
As per the docs, I did following config in Apache:
1. Copied the 'mod_wl_20.so' file found in WLHOME\server\bin directory to the
APACHE_HOME\modules directory
2. Added to httpd.conf :
LoadModule weblogic_module modules/mod_wl_20.so
3. Apache httpd.conf syntax correct : checked by running ' APACHE_HOME\bin\Apache
-t '
4. Restarted WL & Apache.
Now, the weblogic documentation says,
"Test the Apache plug-in by opening a browser and setting the URL to the Apache
Server + "/weblogic/", which should bring up the default WebLogic Server HTML
page, welcome file, or default servlet, as defined for the default Web Application
on WebLogic Server. For example:
http://myApacheserver.com/weblogic/".
For my server, 'http://localhost/weblogic/' - I get a "404 : file not found" error.
What other configuration is needed ? Do I have to specify '/weblogic/' name anywhere
else in Apache configuration file ?
Any pointers will be appreciated.
Thanks,
S

Forgot to mention , I've also added following configuration in httpd.conf :
LoadModule weblogic_module modules\mod_wl_20.so
<IfModule mod_weblogic.c>
WebLogicHost localhost
WebLogicPort 7501
</IfModule>

Hi all,
I had some progress... i disabled the firewall (SELinux) on the Apache server. Before, i had just disabled the firewall from the Weblogic Server. Now, when i access the apache server, it redirects (sometimes, actually) the request to my Weblogic Cluster. Let's say that 50% of the time it works and the other 50% i get the error informed previously.
   I am using the apache user and the ulimit of this user is:

Weblogic 8.1 Apache Plug-In

Where can I find the plug-in for WLS 8.1/Apache 2.0/Windows 2003?

Hi Vishwas,
Thank you for the reply. I forgot to mention that Apache and WebLogic are on Solaris 9 platform.
Accesing a webapp hosted on WebLogic through Apache->plug-in->WebLogic return 500 internal server error, but other webapps hosted on the same WebLogic domain works properly. Looking at the Response Hdrs from WebLogic shows that WLS returns transfer-encoding=chunked. The other webapps which work properly has content-length set and transfer-encoding is not chunked.
So, the question is does Apache Plug-in for weblogic 8.1 SP5 read the chunked data properly?
Thanks,
Janani
