"Extra" modules in Apache/OHS?

Does anyone have any experience with the possibility of removing the mod_oc4j and mod_dms modules from the standard OHS installation?
It seems that they're not really relevant unless we're wanting to use J2EE containers, which ApEx seems to steer very clear of.
We've got them loaded in our installation, which I think is the standard OHS installation, and all I can see that they're doing is adding logging overhead to our installation. I'd like to remove these from the OHS startup if they're really not necessary. Anyone have any ideas, recommendations or experiences you'd like to share?
Earl

Hi Earl,
You can certainly remove them, however there's a couple of things worth bearing in mind -
1) You might want to keep the OC4J if you're going to use it for enabling the printing features in APEX 3.0 (although you can use Tomcat instead, or some other method).
2) If you don't actually use the modules, then they shouldn't cause too much in the way of overhead in terms of logfiles (since they're not used) or processing requirements (any 'decent' OS will be able to swap out processes that aren't being used).

Add and remove modules in Apache

Is it possible to add and remove modules within Apache (actually compile an relink Apache) with a source download form Apache.org (1.3.28?) and incorporate the necessery modules and configuration from Oracle?. I have looked for some kind of documentation for this, but ended up with nothing. Can anybody explain this?.

If you really understand apache and how oracle implements the apache server then yes you could add/remove modules if you have the source code from oracle. I dont think that you can download apache1.3.28 from apache.org and expect to use that source to build an executable that can plug into oracle.

Not able to scale more than 1500 users when using apache (OHS),why ?

Hi,
When scale more than 1500 users, my applications response time degrades.If i use IIS as my webserver I am able to scale more than 3000 users, is there any bottleneck in the oracle apache (OHS) ?
OHS Config
Timeout = 300
KeepAlive = ON
MaxKeepAliveRequests = 100
KeepAliveTimeout = 15
MaxRequestsPerChild = 0

Hi Jean,
Our application contains customised retail webcenter portal on which retail application is hosted.This portal application is not able to scale up more than 10 users.I had created portal application without the customised framework and then for a similar usecase it is able to scale upto more than 50 users but once it hits 100 VU mark it starts giving errors.If it were an issue with client tokens or login,I would have been able to have more than 1 user at a time.It seems to be an issue with custom framework developed on top of webcenter portal.I have faced a similar issue while testing for this app with jmeter also.I was able to test for the webcenter portal app without any customisation for more than 100 concurrent users. But I was not able to test for more than 1 user for customised retail webcenter portal
Thanks,

Where can i download the weblogic modules for apache (source/precompiled)

I have wandered the wonderfull world of the BEA website for 2 full days now and still am not an inch closer to de download site for the weblogic module for apache. That is, i have apache and need to add the weblogic module to it.
Complications are Solaris 10 and apache 2.0.55. So the latest versions of OS and webserver. Is there a precompiled module available or can i get the sources somewhere?
I do have a working module for apache 2.0.53 if someone can confirm that this is supported for 55 that would be fine by me.

At times when the sources were available I tried to build it on a "new" platform (Solaris x86 32bit) and I can tell you: it's NOTHING that is obvious. Building OpenOffice or Mozilla may appear like an easy task. It took me months to get there and to be able to just build the 'build tools'.
On top, many of the sources are (historically) written in a Pascal dialect and are transferred to C with an own precompiler so there are three languages used (C, C++ and Pascal) - so it's a pretty hard (next to impossible) job to learn some algorithms from those sources.

and just to get an idea of the modules and their structure:

Trouble starting Apache OHS

New installation of Oracle 11.1 on Dell RHEL/Linux box. Installed Oracle OHS from here into a separate ORACLE_HOME (=db OH/apex).
opmnctl startall starts up opmn but times out on starting Apache OHS httpd. No errors in HTTP_Server~1.log, the last line is simply execing httpd. More surprisingly, no warning/error messages in ohs/logs/error_log, nothing. opmnctl just hangs for a while and comes back with "time out while waiting for a managed process to start". And then I see the opmn process and one httpd process but port 7780 doesn't respond to requests.
Never had any trouble with this before. Everything seems to be setup right but OHS just doesn't want to startup.
Any ideas? Thanks

No, I am not running SSL. My opmn.xml is the default one, no changes.
OK I found the problem. I did a strace -f opmnctl startall and saw that it was waiting on a blocking read on */dev/random*. Some googling on this shows that an insufficient entropy pool (my poolsize had dropped by 62, below the threshold of 64) is a known issue on headless Linux servers due to the lack of truly random activity like mouse and keyboard movement. All this stuff is new to me, it gets really bizarre, thought I was in a physics class. There are some "entropy generating" tools out there but it looked like overkill to me since I am not running a military grade installation. I simply did rm -f /dev/random;ln -s /dev/urandom /dev/random. /dev/urandom generates random numbers of lesser quality but it doesn't block readers. With this fix in place, opmnctl stopall/startall works fine again. Whew, this was a strange problem.
Hope this helps someone else.

[SOLVED] Error with the php5 module for apache

Hi!
I've installed Apache 2.0.55-1 and PHP5 5.1.4-4. When I try to run the apache server it fails. Then I do httpd -k start and I get:
Syntax error on line 262 of /etc/httpd/conf/httpd.conf:
API module structure `php5_module' in file /usr/lib/apache/libphp5.so is garbled - perhaps this is not an Apache module DSO?
The file libphp5 exists, but seems corrupted.
See you

That version of the package has been built with apache 2.2.x. Be sure to use that version of apache too, as 2.0 won't work with that specific package.

Php module in apache doen't load

I've tried to get php running on the apache server on leopard. I've modified the httpd.conf to load the php5 module (removed the #) but when i open a php file, the screen is blank, and the source shows the php code.
I tried to stop and restart the webserver but it didn't help
Does anyone know what the problem could be? It could be the httpd.conf file, does anyone have a working version of this file? Thanks.

I hadn't setup the provided PHP on my machine yet... when I read your post I decided that if I can help you figure yours out I'll have gotten some milage out of setting mine up, even if I never use it
I could not reproduce your problem. If you need help creating a phpinfo.php file let me know... Here's what I did that worked:
*1. Modify httpd.conf*
I used Terminal to do this stuff, it just seemed easier than fiddling with the GUI.
"cd /etc/apache2/"
"ls" (Just to make sure httpd.conf was where I expected it to be)
"sudo pico httpd.conf"
++Enter Admin password++
Find the line that says "#LoadModule php5_module libexec/apache2/libphp5.so" and remove the hash to uncomment.
Ctrl-x to exit, Y to apply changes.
*2. Restart apache* (I had Web Sharing on already)
Again in Terminal:
"sudo apachectl restart" ("sudo apachectl start" if you hadn't enabled Web Sharing in the GUI)
*3. Move a copy of phpinfo.php into the shared directory*
"cp phpinfo.php /Library/Webserver/Documents/" (Presumes that you've already used cd to get to the folder where phpinfo.php is stored)
*4. Open phpinfo*
Using your web browser:
"http://localhost/phpinfo.php"
I got the PHP info I expected...
PHP Version 5.2.4... Darwin XXXXXXXX 9.1.0 Darwin Kernel Version 9.1.0: Wed Oct 31 17:48:21 PDT 2007; root:xnu-1228.0.2~1/RELEASE_PPC Power Macintosh

Apache or OHS

Which is better for weblogic 12c, the oracle http server (OHS) or core apache? I know that OHS is a customized version of apache for use with oracle applications. but can ohs handle many requests as apache, and is it a good practice to use OHS with weblogic 12c for production environments, or does it have some issues?

Hi Kal,
Oracle http server offers extra modules than that of Apache.
1. mod_certheaders
2. mod_dms
3. mod_onsint
4 mod_oradav
5 mod_ossl
6 mod_osso
7 mod_plsql
8 mod_wl_ohs
Also in case of any issues or bugs that you encounter with this webserver, Oracle will be able to get a fix .
Thanks,
Sharmela

Oracle 9i Lite Mobile Server deploye Problem As Apache Module

I am trying to get the Oracle9i Lite Mobile Server run as a Module under Apache.
my platform is Linux 7.2, which of course is documented as an option.
I managed to install the mobile server and the following document is
the latest from ORACLE site. and is very useful.
http://technet.oracle.com/docs/products/lite/doc_library/release501/readme.htm#new
I have one problem to overcome the module to load in Apache

This does not load due to following error,

I found this post explaining to recompile Apache
This actually means you installed mod_ssl as a DSO, but
. without rebuilding Apache with EAPI. Because EAPI is a
requirement for mod_ssl, you need an extra patched Apache
(containing the EAPI patches) and you have to build this
Apache with EAPI enabled (explicitly specify --enable-rule=EAPI
at the APACI command line).I recompiled apache with the following
./configure --prefix=/usr/local/ssl-apache/httpd-2.0.39
--enable-rule=EAPI ; make ; make install
I still get the same error when I try to load the module.Am I missing
something?
Any help is deeply appreciated.

Scott, I have yet to get WTG server to work as an NT service when loaded as an Apache module.
We've had to load it into a non-service based Apache server (one that runs from the command line in a MS-DOS prompt window). This is on XP Pro.
We've switched to running our WTG server on Linux.

Help debugging an Apache module compile

Has anyone every had any experience adding in modules to apache that use openssl?
We have had great luck installing this module in particular "mod_cosign" with Apache 1.3 standalone but we are having a heck of a time compiling it with OHS.
The module we are using is from:
http://webapps.itcs.umich.edu/cosign/index.php/Cosign_Wiki:Test_install_HOWTO#Compilation_and_Installation
We are compiling this with openssl-0.9.7e
And here is the error we get when we try to start apache
.../Apache/Apache/bin/apachectl startssl: execing httpd
Syntax error on line 245 of .../Apache/Apache/conf/httpd.conf:
Cannot load .../Apache/Apache/libexec/mod_cosign.so into server: ld.so.1: .../Apac
he/Apache/bin/httpd: fatal: relocation error: file .../Apache/Apache/libexec/mod_cosign.so: symbol RAND_bytes: referenc
ed symbol not found
I'm not sure what it is truly missing and why the "RAND_bytes" is missing. I know this is specific issue but I was hoping maybe somebody has some experience with other modules being compiled and help debugging them.
Thanks,
Justin

You should try with the latest apache 1.3.x version rather than with the 2.x version. The mobile server module that has been shipped has been tested with 1.3.x version. Hi! Summit,
Thanks for your good observation.
I already figured that and tried on
apache_1.3.27
I went through all te trouble to compile a EAPI enabled
Apache to fix the 'Symbol resolving problem'
Now I have the EAPI enabled ( pretty much ssl enabled ) Apache_1.3.27
Now when I load the module 'libwtgapach.so'
I get the following log ERRO entry in Apache and it never comes up.
Here is my ewrror log says.
OUCH: nested memory code, to 1 levels.
OUCH: nested memory code, to 1 levels.
OUCH: nested memory code, to 1 levels.

OUCH: nested memory code, to 1 levels.
OUCH: nested memory code, to 1 levels.
OUCH: nested memory code, to 1 levels.
This could still be due to a problem in the Shared Object 'libwtgapach.so' as without it the EAPI enaled Apache works fine.
This is very criutical for me to get the 'Mobile' project we are researching on to get going.
Any help is deeply appreciated, I am trying ORACLE with not much help.
One thing strange though, the olite_50200_linux.cpio distribution from ORACLE download page installation documentation does not even mention about the Apache Module Configuration detalis.
I presume it is implied as trivial.
OR
IS IT REALY SUPPORTED ?

NTLM for Apache web server

First, I didn't find a specific category in the forums for the Apache web server that comes with Oracle 8i and 9i, so if this isn't the right place, I'd like to know where it is.
Anyway, has anyone had success using NTLM with recent versions of Oracle's Apache web server? I had it working with 8.1.7, but when I upgraded to 8.1.7.3, it broke again. It doesn't work with 9.2 either. Oracle support was quite unimpressed that I had even tried it at all, but I think it is something that should be part of an intranet web server in a corporate environment, since Windows is on most desktops.
Thanks,
Andy Johnson

NT Lan Manager authentication for Apache? Are there even APIs published by Microsoft? On the other hand, I would not be surprised if a module exists. (then again Oracle would not support it for their variant of Apache=OHS)

Apache Listener on OAS 4.08

i can't install and run apache properly as a third-party listener on oas 4.08. Apache seems to start, but the red-flag indicates that it isn't running.
what should i do with libapadp.so? docs say i should link it when i build apache. how do i do that?

Hello.
I've got the same problem, this is how far I've gotten:
[root@thor conf]# httpd
[Thu Aug 24 22:58:11 2000] [warn] Loaded DSO modules/ndwfapd.so uses plain Apache 1.3 API, this module might crash under EAPI! (please recompile it with -DEAPI)
[root@thor conf]#
I've figured that I must recompile apache with:
./configure prefix=/path/to/install/apache enable-rule=SHARED_CORE
What about extra modules that come with the standard Mdk rpm? What switches is the mandrake rpm compiled with?
I'm too worried about wrecking my apache installation.
Basically my question is:
How do I recompile and get apache working with the least differentiation from the standard mdk rpm that came with Mandrake 7.1 but including support for my additional module (for Oracle Application Server)?

Compiling Apache 1.3.9 & PHP 3.0.12 to use Oracle 8.1.5 on SuSe 6.2

Hi!
I am trying to compile the above packets but am running into massive problems.
PHP3 compiles well, if i try to use the "normal" static module for Apache, but the Apache configure script says that it needs an ANSI C compiler and stops.
I am using GCC 2.7.2.3 with the bugfixes from SuSe.
Since that did not work I tried the configuration as a Dynamic Module. The Apache "Readme.config" explains two ways to do so, but the first has the same problem with GCC and the second (via APXS) compiles Apache without problems, but PHP3 wont compile since it does not find a library. The exact error is: "/usr/i486-linux/bin/ld: cannot open -lclntsh: No such file or directory"
I found a libclntsh.so.8.0 in the oracle/lib directory, but since i fumbled around with this library (i tried ln -s libclntsh.so.8.0 libclntsh.so) sqlplus says libclntsh.so.8.0: cannot find file data: no such file or directory (even now that the link is deleted again).
And PHP still wont compile. Any ideas would be welcome.
P.S.: Is it normal that Oracle has to be told NOT to create a database during install, TO create a database???
We worked for 3 days on the Oracle installation and that was the only way to install Oracle without errors.
thx
