OracleAS Web Cache Architecture - Web Cache placed at Customer site

Thanks In advance for all your support.
What I am looking for is an WebCache technical architecture slide where WebCache is placed at the customer sites and connecting to the APPS server @Oracle ADC.
If you would have this information great or if you could provide any other place or person that I may contact that could provide this information, this would be greatly appreciated.
Thanks -- Gary

Hi Gary!
In theory it does not matter where you place the webcache. However you need to make sure that the connection between the webcache and the origin server is encrypted using SSL (HTTPS).
I would suggest not to set the webcache system at the customers site. Who is going to manage the box? Who is responsible for it?

ADF application integrating with Oracle Web Cache

Hello,
I am trying to integrated my ADF 11g application with Oracle Web Cache. I used this link http://andrejusb.blogspot.com/2010/06/oracle-webtier-11g-configuration-for.html for it.
I am able to access my ADF application using webcache port 7785.
I created few caching rules in the Oracle Web Cache. And in the popular request section of the Oracle Web cache i see jpg,png and other image files cached.
But the issue is when the application access images like /testapp/test/images/abc.jpg?_adf.ctrl-state=5b0s7lzfo_29 . I created a caching rule with regular expression ^/testapp/test/images/[A-Za-z0-9_]*\.(gif|jpeg|png|jpg)\?_adf\.ctrl-state=[A-Za-z0-9_]*$.
But when i access the popular request in em i don't see the URL given above as cached. The caching reason it specifies as URL contains query string.
I am not sure if i need to do anything additional to cache these URL's as well.
Thanks!
Ram

Yes that works. But my question is how to cache the urls which has querystring. I was trying to give a regular expression to match the url so that the url which contains parameters like _afrLoop which changes with each HTTP request can also be cached.

Oracle Web Cache and OBIEE 11g

Anyone using Oracle Web Cache with OBIEE 11g?
Can I get an insight into whether this solution is beneficial? Or I shouldn't even bother.

No iam not using oracle web cache
Can I get an insight into whether this solution is beneficial? Or I shouldn't even bother.I dont have idea about it,but i think its not beneficial ,anyways there is OBIEE cache that is more than sufficient.
hope answered your question.

Forms6i Server (9iAS R1.x) loadbalancing using Oracle Web Cache

Hello,
I have read that it's possible to use Oracle Web Cache as a software load balancer between multiple Application Servers.
We are running Oracle9iAS R1.0.2.2.2a, with Forms/Reports6i servers on 2 Win2k boxes i.e our Forms6i application is deployed on two seperate boxes in two distinct locations. Users at each location, use their respective App Server url.
Since the application is the same i.e. Forms6i code/fmx is the same for both locations, I am looking into loadbalancing and failover capability that Web Cache might be able to provide.
So basically all users from both locations will point their browser to this Web Cache and the Web Cache will direct each connection to either of the two boxes. So, if either of the boxes dies, Web Cache will divert the requests to the other box.
My concern is whether Web Cache supports this for the Forms requests that it will receive from the users. We are using Servlet Deployment of Forms.
Has anyone done this or has any ideas as to whether it's going to work or not?
Thanks,
Manish

Manish,
we tested this but came across problem with Webcache that have to do with the jsession Forms uses. This is fixed for Oracle9iAS 9.0.2.x. So if you want to run Forms with Webcache in front, then please do this using the latest version of Oracle9iAS V2 Webcache. For Oracle9iAS V1 and Forms Services we recommend not to use Webcache but do the load balancing via JServ.

Problem in using OracleAS Web Cache as Load Balancer

I have two machines:
aimssrv.world.com and aimsrep.world.com.
Both of above machines are running Redhat Linux AS 4.
On both machines, I have installed Oracle Forms and Reports 10g Services. I have deployed my application on both machines.
I am able to access my application at aimssrv.world.com by doing:
http://aimssrv.world.com:7778/forms/frmservlet?config=aims
and I am also able to access my application at aimsrep.world.com by doing:
http://aimsrep.world.com:7778/forms/frmservlet?config=aims
I have implemented OracleAS Web Cache at machine aimssrv.world.com, and have enabled the Load Balancing.
In Origin Servers, its showing me two servers:
Host => aimssrv.world.com, PORT=> 7778, Routing=> Enabled, CAPACITY=>100, Failover Threshold=>5, PING URL=>/, PROTOCOL=>HTTP
Host => aimsrep.world.com, PORT=> 7778, Routing=> Enabled, CAPACITY=>100, Failover Threshold=>5, PING URL=>/, PROTOCOL=>HTTP
In Site Definition, I have following information:
Host Name=> aimssrv.world.com, PORT=>7777
In site-to-server mapping, I have following information:
Priority      Host Name      Port      ESI Content Policy      Host Name      Port      Proxy
1      aimssrv.world.com      7777      Unrestricted      aimssrv.world.com      7778      No
aimsrep.world.com      7778                                    No
2      *      7777           Exclude Fragments      aimssrv.world.com      7778      No
3      *      *           Exclude Fragments      aimssrv.world.com      7778      No
In Session Binding, I have selected "JSESSIONID" as session, and "OC4J-based" as session binding mechanism.
Now please guide me as how would I run my application by using the OracleAS Web Cache?
What would be the URL?
Do I need to make any changes in httpd.conf files of aimssrv.world.com and aimsrep.awc.com?
Please guide.
Thanks and regards

hi,
i hv recently configured webcache load-balancing for my 2 mid-tiers.I did not upgrade pre-requisite webcache upgrade patch 4569559 to my 10g rel 2 10.1.2.0.2 OAS and it still worked a bit but I do have some doubts why oracle recommends installing this patch before configuring webcache load-balancing.Have u?
btw u need to collapse all the features of webcache of caching to turn on http load-balancing.U need to add a parameter to internal.xml (LOADBALANCE ON="YES") and register origin servers of both servers with each other and map ur sites so that origin servers of both servers will cater sites of server1 and server2 at the same time.
what worked for me is i registered origin server of server1 at server2 and origin server of server2 at server1 and mapped site of server1 (http://server1:port/forms/frmservlet?config=something) to work with origin server of server2 as well at site-to-server page so that origin servers of both servers will load-balance my server1 site and vice-versa.
But still its not seamless.The initial site request was still being routed to the server which is DOWN first and not seamlessly routed to other server which is UP.Maybe webcache upgrade patch would hv done this seamlessly????

Hi Fahad,
I am sorry I am not sure what the solution to your issue is. However, I was wondering why you are not attempting to install Oracle 10g as opposed to 1.0.2.2.2?
I am guessng here but perhaps the 10g database is incompatible with a 1.0.2.2.2 install.
Hopefully someone else may be able to provide more useful feedback.

Oracle Portal with Oracle Web Cache

How can I configure Oracle Portal (or Web Cache) to work together?
I have installed and started both of them. Now, Web Cache works fine with standard html pages (for example Apache docs) but after trying to reach portal the url is redirected to standard port - on which Portal runs (Web Cache works on 1100 and Portal on 7778).
So it seems that portal pages are not cached.
Web Cache:
Application Web Servers:
hpwin 7778 100 30 5 / 10
Where can I find any information about that?
best regards
KJ

Portal PM, I thought you said that this solution would not work. Everyone I have heard so far has said that you cannot configure webcache to work with Portal documents. Does this work or does it not?
Read the messages below from the bottom up.
It's not possible to do that today.
In 9.0.2 (the next release) we will be using WebCache configured out of the box so you won;t need to, however, till then you cannot use webcache with Portal 3.0.x
Thanks
Portal PM

please try using this configuration on http.conf
Port <webcache port>
Listen <apache listen port>
ServerName <webcache hostname>
you must running ssodatan script again.
Note :
this config only make portal work together with webcache.

Oracle Web Cache Administration and Deployment Guide

Does anyone know where the Oracle Web Cache Administration and Deployment Guide is?
From Oracle9iAS Documentation Library CD-ROM,
it says this document is in OTN. However, I just can't find this document in OTN.
Any idea?

Rick -
try this link on for size:
http://technet.oracle.com/docs/products/ias/doc_library/1022doc_otn/caching.102/a90372/toc.htm
To get to the (iAS documentation, try this path through technet
Top Level
-> click documentation link on RHS
-> click Oracle9i Application Server link
-> click Generic Documentation Library link (HTML) or (PDF)
That should get you to the documentation library, from which you can view all the component doc, install guides, performance guides, etc.

Oracle Web Cache - Load Balancer Mode

Hello,
I am facing a problem related to fault tolerance in Oracle Web Cache
My environment:
2 Nodes of Oracle Application Server 10.1.3 configured in cluster.
have configured Oracle Web Cache (in LoadBalancer mode only) to simulate a BigIP load balancing above these two oc4j node. This to be used as fault tolerance so if one http request will fail the LoadBalancer will direct it to the second oc4j (its http server).
I have used the defaults recommended by Oracle documentation for configuration clustering load balancer using Oracle Web Cache and using JSESSIONID for Session binding with oc4j-type. I left all other cluster/server setting to default
Problem:
The problem is when I am shutting down one oc4j instance the Oracle Web Cache tries to keep the session with the un-available oc4j node and not direct the session to the other oc4j node.
If I choose to start a new session (loose current work) than it does work with the second (alive) oc4j node, but than where is its fault tolerance??
What do i need to do to keep working with the same session over the second oc4j node. My deployed Web App is enabled to work in cluster, using Oracle Application Server console. Here is its orion-application.xml

Will appreciate any help !

is OHS/apache deployed between web cache and your OC4J? if so, i think since OHS/apache is alive to web cache, web cache keeps routing to it.
maybe in your script, you can shutdown both OHS/apache and OC4J totgether so web cache can correctly route.

Problems about deploying Oracle web application (Forms, Reports)

I am going to deploy Oracle web applications (Forms and Reports) and plan to use the same server machine for both Application web server and Database server.
1. How can I enable SSL (for data encryption) on Application web server for Oracle Forms ?
2. Since both Application web server and Database server will use the same machine, do I still need Oracle Advanced Security for data transmission between Application web server and Database server if data encryption for transmission is required ?
3. Can I user Oracle Forms to call Oracle Report on web as I did in Client/Server in the past ?
Experts like you may have come across such problems. Would you please give me some opinions/ideas ?
Regards,
Richard

1. check the paper about the Forms servlet architecture on otn forms section for SSL tips.
3. Check the reports and forms integration paper on otn too.

Oracle Web Center Suite and Oracle Portal

1)What is Oracle Portal and why it is used?
2)What is Oracle Web Center Suite and why it is used?
3)What is the difference between Oracle Portal and Oracle Web Center Suite?

1) Oracle Portal is the Portal product that was deployed together with the application server before weblogic server. It is still used a lot for corporate intra and extranets. It is mosly used for intranets and extranets. When you bought the licence for the application server you automaticly had the licence for Oracle Portal. That's why it is so popular.
Oracle portal is not realy standard based. You mostly will create portlets with PL/SQL or PDK and not realy use the JSR168 standard.
No with Oracle Portal 11g you can consume JSR168 portlets using WSRP.
2) Oracle WebCenter suite is the next strategical choose of oracle in portal software. Webcenter is an enterprise 2.0 portal environment while oracle portal is more web 1.5 and has limited web 2.0 stuff. Oracle Portal comes with a complete UI for the user to use to create websites and groups but webcenter is more a framework to incoorporate enterprise 2.0 features into your own fusion web application. Webcenter suite comes with Webcenter spaces. THis is a complete UI to create collaborative websites.
Webcenter framework is a powerfull framework to create complete enterprise 2.0 sites.
3) The difference... Oracle Portal is an old product and will not be developt anymore. I've heard portal 11g will be the last version meaning support will stop at 2014. Webcenter is a new product to create state of the art enterprise 2.0 websites.
Oracle portals is not build on standard and is not realy standardbased meaning is you develop portlets for portal you will not be able to use them in other portals.
Webcenter on the other hand is completly standard based. It is JSR168 compliant and in the near future it will also support JSR286.
Oracle portal is PL/SQL based while webcenter is completly java based, based upon the ADF framework from oracle.
Because WebCenter is based upon the ADF framework you can use the complete ADF framework for your application. For example consuming webservices are very easy in webcenter. If you are using a service oriented architecture you will have lots and lots of work to integrate it with portal. With webcenter this is peace of cake.
Hope this helps you :)
If you have other questions, just let us know.
