|Industry has started talking about Fusion Middleware & Oracle recently certified 10g Application Server (Portal 10.1.4) with Oracle E-Business Suite so I am discussing overview of Application Server part of Fusion Middleware Family.
Overview of 10g Application Server
10g Application Server Consist of Infrastructure Tier & Middle Tier
What is Infrastructure Tier ?
Infrastructure Tier provides Infrastructure Services to 10g Application Server & consist of following technical components
- Database -> To Store User/Applications Identity Data (Portal,Wireless,OID data)
- OID -> Oracle Internet Directory, to store User Credentials, Schema passwords, Application details & lot more ...
- HTTP Server -> This Web Server (OHS, Oracle HTTP Server) on Infra Tier is used to access SSO (Single Sign-On Server) & OIDDAS (OID Delegated Administrative Services)
- OC4J -> Oracle Container for J2EE (OC4J_Security for SSO), You have additional OC4J_OCA if you have OCA (Oracle Certifying Autority). OCA is Optional component in Infrastructure Tier
What is Middle Tier ?
Middle Tier is tier where application Server & applications logic resides. It consist of following Technical Components
- HTTP Server -> This OHS (Oracle HTTP Server) is separate from above OHS & this is OHS from where users access application Server like portal, wireless, j2ee
- OC4J -> These are container which provide place holder for j2ee or web applications . Applications are deployed on OC4J's. 10g AS comes with default OC4J name "home", you create more OC4J depending on your requirement
- Web Cache -> Web Cache acts as cache for fast response to web server.
Logical Services for Infrastructure Tier
Above was technical components of Infrastructure Tier , Logically Infrastructure Tier consist of Two main categories which are
What is Metadata Repository ?
MR is similar to Database Metadata & MR you can further classify as
Metadata repository for Products (Like Portal, Wireless, BI) This MR usually is user data. Lets assume I created some pages, documents in Portal or User entered some data in any application , such data when stored in database is called as Product MR
MR for OID - Oracle Internet Directory contain some data & data related to this , one can classify as MR for IM (as OID is part of Identity Management - discussed later)
MR for SSO - Oracle Single Sign-On data & schema definitions , one can classify as MR for IM (as SSO is part of IM)
So broadly there are three kind of MR (that's how I classify MR)
What is Identity Management ?
Logical Grouping of Services which help in Managing Identity is called as Identity Management.
Identity management Consist of following Services like (Discussed later in Detail)
- OID Oracle Internet Directory
- DAS Delegated Administrative Services
- DIP Directory Integration & Provisioning Services
- SSO Single Sign-On Service
- OCA Oracle Certifying Authority
Explanation of these Services, why they are required & one example of all these services ..

It would be appreciated if you share oracle app serer OC4J...
have a nice dat
Sure, I will try to cover OC4J soon, which is component of application server (Though you can install it standalone version as well)
Thanks for your reply..
ya i have installed OC4J and i will try to deply some application on this..
but i am in confusion between terms like oracle app server and Oc4j...whether oc4j is a component in app server?
if yes what would be its functionality..
Thanks in advance..
Yes OC4J is component in Apps Server and used to run application deployed on that OC4J
but generally we will deploy our application into application server..
as oc4j is a component of applicaion server.whats its role in that..
As per my understanding,onb oc4j we can run different types of applications like container..
correct me if iam wrong..plz explain it in your words..
I am new to Oracle Application Server environment. Please advice me if I am wrong ..
I have an environment to be upgraded. It's running on Oracle Apps server 10.1.2.0.2 with a seeded metadata repository database 10.1.0.5 and portal version 10.1.4. I want to upgrade the database to 10.2.0.3 and Apps Server to 10.1.2.2. Right now MR and IM are in the same oracle home. After upgrading the database server I have a new oracle home(10.2.0.3), where I don't have the identity management components. Should I do an upgrade on the IM also in this case?
First install 10.2.0.3 database in seprate oracle_home for database and upgarde database in new oracle_home now apply patch OAS patch 10.1.2.2 in existing 10.1.2.0.2 Infra tier and Middle Tier .
after upgarde you will have three oracle_home's
10.2.0.3 for MR & IM database
10.1.2.2 for IM (OID, SSO) binaries
10.1.2.2 for middle tier binaries
Thanks for your reply..
I have already applied the 10.1.2.2 on MT, without applying on IM.
Can I apply the 10.1.2.2 on IM now?
Will this be an issue later, if I keep the IM in 10.1.2.0.2 itself?
What Edition of Oracle Application Server comes with E-business suite 11i. Is it the enterprise edition? Can the Oracle Application Server "Java Edition" work with E-business Suite 11i ?
Sathmika, with 11i oracle ship 9iAS i.e. version 126.96.36.199.2 for web server and 8.0.6 for developer.
Can you elaborate why you need info related to Java Edition or EE so that I can answer your question accordingly ?
We have our Apps setup in multi-node environment and one of the nodes serve our external users (DMZ setup). On that server we run only Apache Server (and not forms/reports servers). My questions is, for that server can we install a lighter weight Application Server rather than the entire IAS_ORACLE_HOME and still be able to run Applications.
Oracle comes with multiple version of AS and one of that is the Java Edition. Can we use that Java Edition AS to serve E-Business Suite users (or does it have to be a clone of an rapid installed IAS_ORACLE_HOME).
Thanks for your time Atul.
Supported & Certified way is that it should be clone of rapid installed IAS_ORACLE_HOME .
i am really a grt fan of urs boz ur blog really helps me a lot.i am a fresher as a APPS DBA. so plz advise some basic commands of linux which is mostly uses by apps DBA.

Can anyone recommend the well-priced Patch Management software for a small IT service company like mine? Does anyone use Kaseya.com or GFI.com? How do they compare to these guys I found recently: [url=http://www.n-able.com] N-able N-central configuration management
[/url] ? What is your best take in cost vs performance among those three? I need a good advice please... Thanks in advance!
Please advise on the most reliable Patch Management system out there?
I did my research on the web and discovered the following:
They all look different... Does anyone has other suggestions?
As well did anybody else hear of that software:
