Configure Oracle HTTP Server infront of Oracle WebLogic Server mod_wl_ohs

Hi Atul,

I’ve noticed that you have a good knowledge of the Oracle Imaging platform…. Can you tell me if there is a way to read some old MO disks, written with Optika software, with some TIFF files? I did a RAW data dump of a disk, and on the header I can see the “Copyright Optika”, and “SYSSQL” strings…

I’ve had an SR open for 2 weeks waiting for this information.
Found this page and had my DMZ server running within 15 minutes.
THANK YOU for posting this!

Hello Atul

Is it possible to configure the webgates on the weblogic http server embedded in the Weblogic app server, without the Oracle http server in front of it proxying requests.

Thanks
Karen

@ Karen,
What is version of OAM & Weblogic ?

OHS is recommended & easy way

I have come across an issue where the console hangs when using the Oracle http server only during activating changes in the console.

Would appreciate if you could any comments on this.

Hi Atul,
Is Oracle HTTP Server mandataory to access Weblogic Admin Console?.I have an Oracle HTTP (mod_wl_oh.conf or through some other files in httpd.conf ) configured for Managed servers and did not have entry for admin server but still able access admin console.

Please let me access flow. My environment
FMW11gR1, have Weblogic clusters.

@ Lokanath,
No HTTP server is not mandatory to access WebLogic Admin Console and same applied to Managed Server. WebLogic Admin Console and Managed Server comes with default HTTP listeners (7001 for Admin Server and for Managed server one you define during installation)

Why then you configure HTTP server infront of WebLogic ?
This could be for number of reasons like
a) You do not want to expose WebLogic Server (Admin or Managed) directly to end users for security reasons and want users to come via OHS
b) You want to configure Single Sign-On solution like Oracle Access Manager (in this case though you can configure SSO solution directly with weblogic without a need of OHS but configuring SSO via OHS makes configuration/deployment easy)
c) For multiple managed servers in cluster and you want to give single URL to end users.

This post was very useful for me and I have the same set up, however I’m unable to get the OHS to pass client certificates in the header.

When using the OHS user it prompts me to select my client certificate, I select it but nothing gets pushed to WebLogic. I put the same user certificate on WebLogic in a keystore and going through that url again it prompts me to select a user certificate and I am able to retrieve it from the headers.

I know I haven’t gone into much detailed but any idea why this could be occurring?

Dear Atul,

This is the body of the modified file: mod_wl_ohs.config (ps. does the hash key infront of a line in the config file comment is?)

This empty block is needed to save mod_wl related configuration from EM to this file when changes are made at the Base Virtual Host Level

WebLogicHost
WebLogicPort
Debug ON
WLLogFile /tmp/weblogic.log
MatchExpression *.jsp

SetHandler weblogic-handler
PathTrim /weblogic
ErrorPage http:/vmucm:7001/

the link I am trying to access is:(http:/vmucm:7777/console) is should redirect me to the Weblogic console page, it shows a page cannot be found message.

yet, when I try to access both the weblogic or the OHS console directrly the work fine.

one other question is that you ve refered me to a page that had more configurations for OHS, Page: (http://download.oracle.com/docs/cd/E12839_01/web.1111/e10144/getstart.htm#BEHGIDCB)
Section: (4.4.4 Configuring the mod_wl_ohs Module)

I cant seem to locate where this admin screen is. And is this additional configuration required or the mod_wl_ohs modification is enough?

@ ROCKSTAR

Create an entry like

SetHandler weblogic-handler
WebLogicHost [weblogic_server_name]
WeblogicPort 7001

SetHandler weblogic-handler
WebLogicHost [weblogic_server_name]
WeblogicPort 7001

1. Change [weblogic_server_name] to server name where weblogic admin server is running
2. Restart OHS and try accessing url using OHS
Restart

i have copied the file again and it is like this
This empty block is needed to save mod_wl related configuration from EM to this file when changes are made at the Base Virtual Host Level

WebLogicHost
WebLogicPort
Debug ON
WLLogFile /tmp/weblogic.log

PathTrim /weblogic

not as in the previous post i have made

@ KINGSTAR,
Don’t use EM, update file directly. Take backup of file before updating.

DEAR ATUL,

Hi,
I am a newbie and trying to study OAM:
I am trying to install OAM 11g, on windows 64-bit. Everytime time i try to patch webtier 11.1.1.2 with 11.1.1.3 i get the following error
Error in writing to file ‘C:\Oracle\Middleware\Oracle_WT1\ohs\modules\mod_wl_ohs.so’. [C:\Oracle\Middleware\Oracle_WT1\ohs\modules\mod_wl_ohs.so (The process cannot access the file because it is being used by another process)]

and a number of similar errors after i skip this one.

Any suggestions would be really helpful.

@ Vidya,
Is OHS server running while you are applying patch 11.1.1.3 ? If yes shutdown OHS before applying 11.1.1.3 patch

Hello,
Is pssobile to use one OHS11g as proxy server for two WLS domains’ applications. I noticed that you configured for one domain with port 7001. But I have two WLS domains with ports 7001 and 7010. How can I utilize one OHS to protect the two WLS domains applications?

TIA

@ Lukem
Yes it is possible but these two application should have different URI like /app1/**** for application on domain1 and /app2/*** for application on domain2

What about sessions replication. It it work with OHS?

We have an existing Shibboleth IdP that we use as part of our campus SSO options. I would like to use that IdP to authenticate several of the components that we use from OFM 11g — specifically OHS and Oracle Report Server to start. Do we need to install OIF and OAM to do this?

Thanks,

@ Alexander,
For most of application yes session replication works but if there are few application like ADF where you need to specify in application code that this is going to be in HA . More information at section 6.1.3.2 http://docs.oracle.com/cd/E23943_01/core.1111/e10106/adf.htm#CACHBHEF

Hello Atul,

How to redirect APEX requests from OHS to WebLogic Server?

Hi ,

I recently installed weblogic 12c in windows and below are my domain details

Cluster name – test-cluster having two manage server in it ie server1 and Server-2 in listening on port 7003 and 7004 .

Now i have deployed an app name myapp on the cluster and it is accessible if i access it through manage server port.

I have installed OHS and i want to proxy my request so that my request goes through OHS to my app.

I configured the same in mod_wl_ohs conf file and the details are below :

SetHandler weblogic-handler
WebLogicHost localhost
WebLogicPort 7003

SetHandler weblogic-handler
WebLogicHost localhost
WebLogicPort 7004

SetHandler weblogic-handler

I have the webtier HTTP server in front of weblogic server. I’m trying to do 2 way SSL. The client certificate is not being passed in the header to the application. I found some info about adding parameters into httpd.conf but most were depreciated and opmn would not start. I used the 10.3.5 plug-in document.

Your website is always helpful and easily understood. Thank you!

Hi,

I configure HTTP Server as Webgate redirect to my app which is a Weblogic Portal page.

But the page by request to HTTP Server shows less than page from request directly to WLS

http://imageshack.us/photo/my-images/856/captureinc.png/

What should i do to fix this problem?

We are using inbound SSL at our OHS server. This is terminated there and we then use mod_wl_ohs to proxy requests to the admin server console on WL at 7001 – so no SSL from OHS to WL.

Because the WL admin app generates non-SSL links we also have to catch these using a port 80 listener in OHS and redirect back to OHS using SSL.

However, this will not work for POST requests generated within the WL admin server as the POST data is lost when redirecting from 80 to 443. For example testing a WL data source uses POST.

Is there any way to overcome this without having to use SSL between OHS and WL?

Thanks,
Bernie

Atul, thanks for your prompt – instant? – reply!
In fact setting just WLProxySSL On has done the trick after enabling the plugin in WL.

Many thanks for your help!

Bernie

@ Girish,

Do you mean display is running locally on laptop and tunneling .

If this is the case then this is common network issue. Install using vnc server or install from client which is on same subnet as server.

Hi Atul,

I installed OHS web tier with “Install Software – Do Not Configure” option and started the config.bat

I am stuck at Specify Weblogic Domain Screen”

Error “INST-07242 Unable to connect to weblogic admin server”

what name should i give in the Domain Host Name.

My weblogic domain host name is “el01cn01”
The hostname of the server where I am installing web tier is “ucloud2”

I tried giving both the names as well as localhost, but still it is not going forward.

Thanks a lot Atul, for your advice on OHS Config.

I have on more thing to clarify.

I am starting weblogic admin server by using script. It starts fine, but when i exit that session it shutdown. It is a production environment. Is there any that I keep it running, even after I terminate or exit from that sesssion. I mean how to keep it up running 24×7.

weblogic@el01cn01:~$ ./startWebLogic.sh &

Hi,

I have configured the OHS in front of weblogic as per the steps. The request is received from HTTPS client and processed by my service. However the response is not being posted back to the https client. Please advise what can be done for such issue.

Thanks
-Mannat

Hi Mannat,
This problem arises because Weblogic doesn’t know that you’re using SSL as it only sees HTTP requests and so builds its links to use HTTP. To make it use HTTPS carry out the following changes:

1 Login to the Weblogic Administration Console
2 Under Domain Structure open ‘Environment’ and then click ‘Servers’
3 Click on Admin Server and Advanced
4 Check the Web Plug-In enabled box and Save
5 Repeat for all other managed servers

Go back to the home pages and, under ‘Preferences’, select ‘Shared Preferences’
Uncheck ‘Follow Configuration Changes’ and Save.

You may then need to bounce the Weblogic stack.

Regards,
Bernie

Bernie,

Thanks a lot for the response. However after making the changes as mentioned above, I still don’t see the response being sent.
Kindly advise.

Thanks

-Mannat

Hi Mannat,
check your entries in mod_wl_ohs.conf – do they look like this?

WLProxySSL On
SetHandlerweblogic-handler
WebLogicHost
WeblogicPort

You could also edit your httpd.conf to enable a listener on port 80 but redirect all requests to 443 – this is not very efficient but would catch any non-SSL redirects.

Listen 80
.
.
.

# Rewrite to SSL for all requests
RewriteEngine on
Options +FollowSymLinks
RewriteCond %{SERVER_PORT} !^443$
RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [L,R]

Hope that helps,

Bernie

Update – in the previous response the bracketed/tagged lines were removed – see below….

Hi Mannat,
check your entries in mod_wl_ohs.conf – do they look like this?

‘open bracket’Location /some_URL’close bracket’
WLProxySSL On

WeblogicPort ‘Your WL server non-SSL port’
‘open bracket’/Location’close bracket’

Hi!

What is about the cold failover? I have two weblogic servers without cluster, but with the same options. Can the OHS mod_wl_ohs use the simple round-robin to forwards requests all available weblogic servers? Can it check which weblogic is available, if there are not in cluster?

Thanks, Sri

I have:
A) a managed server listening on hostname:7008
B) an OHS Webtier installation listening on hostname:7777
C) OAM installed with a webgate protecting 7777
D) mod_wl_ohs configured to have OHS proxy for the weblogic managed server (7008) so that all requests to hostname:7777/application are protected by SSO.

Problem is that if you are clever and point your browser to hostname:7008/application you can bypass SSO. Is there an easy way to get weblogic to NOT answer on 7008 or redirect to 7777 maybe?

Thanks for the tip Atul. Great site!!

Hi
In one of our Siebel implementations, the SunOne Web server is used with the Siebel App Server. Along with these, we have 2 web applications for Reporting (BI Publisher) & Rules Engine (OPA) hosted in Weblogic Server. The Sibel App Server communicates with these applications and users DO NOT directly interact with these applications.

We are debating over, should we use a ‘Oracle HTTP Server’ as web server for Weblogic App Server, or would ‘Weblogic App Server’ themselves be sufficient ?

Since there are no users who directly hit these 2 web applications in Weblogic (BI Publisher & OPA), and also there are not much of static content to be delivered, does it really makes sense to have a OHS web server ? How do you think it would benefit by having it ?

Hi Atul,

I Installed weblogic12c in one server and OHS in One server.Now i have to configure the connection between those two.There is no clustered environment and i am working for test environment.
I am working for bank there will be so many request and how can i modify my configuaration files bcoz every request wil come to that.For security reasons OHS will be the frontend for customers.i have created one domain and one OHS instance.
Weblogic Domain admin name:admin server port 8001
managed server name:server1 port 8003

How can i configure these and u said for security weblogic shoulg not come for customers only OHS has to be visible.so please give me some suggestions.Bcoz so many requests will come for that url how i can allow all requests.

Hi Atul,
I’m protecting Webcenter application [on HTTP] with OAM and /webcenter is unprotected.
Request comes through Load balancer which is on HTTPS and Webcenter is on HTTP, because of this the below files are getting blocked unless I manually unblock them in browser. [because of mixed content – HTTP vs HTTPS]

http://wcp.test.k12lds.memsdc.org/webcenter/adf/spaces/skins/publichtml/publichtml.css
http://wcp.test.k12lds.memsdc.org/webcenter/oracle/webcenter/webcenterapp/jsLibs/WebCenterLogin.js

Is there anyway I can tell OHS server to change these from http to https? So that these files wont be blocked and page looks good?

Thanks

Richard,
Has OAM been upgraded to 11.1.2.2 by any chance? I saw possibly similar issues after 11.1.2.0 -> 11.1.2.2 which required an SR to fix a broken config file.

An alternative could be to edit the file directly in the ohs1 config directory.

Dear Atul,

I have already configured cluster on two server and load-balance. How can I monitor sessions on two servers centralized ? How can to config HA for OHS ?

Thank you so much.
K.P

Hi Atul,

Thanks for the very precise details about the configuration. I am using OHS 12.1.3 and I’ve been trying to get the WebLogicCluster configuration working. I have a standalone OHS instance that i am trying to configure to access the Weblogic cluster. I followed the steps given in the oracle site with no use so far. Is there any specific instructions that I should be doing apart from following https://docs.oracle.com/middleware/1213/webtier/PLGWL/oracle.htm#PLGWL553 link. I keep getting “weblogic: parseJVMID: could not resolve hostname ‘-xxxxx’. Returning NULL from parseJVMID” in my instance log.

I have made sure that i give the configuration exactly matching the cluster Address in weblogic. Weblogic-Plugin Enabled is set to true for the cluster and both the managed servers are up and running. I have run out of options figuring the configuration as most of the blogs and oracle documentation show it is pretty simple and straight forward.

Appreciate your early reply as I am nearing the deadlines.

Thanks,
Anil

Hi Atul,
Me & My team is stuck with one issue.We are working with OSB WS.

I have one WS that is running over OSB cluster, This OSB cluster has 2 nodes, When i am trying to access WS with load balancer IP and Port, WS is accessible but in the WSDL WL5G3N4:address part is coming the address of nodes based on round robin algo of cluster.

We also try with configure cluster with Frontend Host/port information.
But it also not solved with our problem.

OSB Server configuration is look like as available on this blog.
