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.<\/p>\n
Overview of 10g Application Server<\/strong> What is Infrastructure Tier<\/strong> ? What is Middle Tier ?<\/strong> Logical Services for Infrastructure Tier<\/strong> What is Metadata Repository ?<\/strong> So broadly there are three kind of MR (that’s how I classify MR)<\/p>\n What is Identity Management ?<\/strong> Explanation of these Services, why they are required & one example of all these services .. If you don’t see this mail in your inbox then check your Junk eMail Folder <\/strong> <\/strong><\/p>\n
10g Application Server Consist of Infrastructure Tier & Middle Tier<\/p>\n
Infrastructure Tier provides Infrastructure Services to 10g Application Server & consist of following technical<\/strong> components
– Database<\/strong> -> To Store User\/Applications Identity Data (Portal,Wireless,OID data)
– OID <\/strong>-> Oracle Internet Directory, to store User Credentials, Schema passwords, Application details & lot more …
– HTTP Server<\/strong> -> 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<\/strong> -> 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<\/p>\n
Middle Tier is tier where application Server & applications logic resides. It consist of following Technical<\/strong> Components
– HTTP Server<\/strong> -> This OHS (Oracle HTTP Server) is separate from above OHS & this is OHS from where users access application Server like portal, wireless, j2ee
– OC4J<\/strong> -> 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<\/strong>“, you create more OC4J depending on your requirement
– Web Cache<\/strong> -> Web Cache acts as cache for fast response to web server.<\/p>\n
Above was technical components of Infrastructure Tier , Logically Infrastructure Tier consist of Two main categories which are
Identity Management <\/strong>
& <\/strong>
Metadata Repository<\/strong><\/p>\n
MR is similar to Database Metadata & MR you can further classify as
Metadata repository for Products<\/strong> (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 – <\/strong>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<\/strong> for SSO<\/strong> – Oracle Single Sign-On data & schema definitions , one can classify as MR for IM (as SSO is part of IM)<\/p>\n
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<\/strong> Oracle Internet Directory
– DAS<\/strong> Delegated Administrative Services
– DIP<\/strong> Directory Integration & Provisioning Services
– SSO<\/strong> Single Sign-On Service
– OCA<\/strong> Oracle Certifying Authority<\/p>\n
