In computing, the Oracle Application Server 10g (the "g" stands for Grid), consists of an integrated, standards-based software platform. It forms part of Oracle Corporation's Fusion Middleware technology-stack. The heart of Oracle Application Server consists of Oracle HTTP Server (based on Apache HTTP Server) and OC4J (OracleAS Containers for J2EE) which deploys J2EE-based applications. The latest version of OC4J offers full compatibility with the J2EE 1.4 specifications. Oracle Application Server became the first platform designed for grid computing as well as with full life-cycle support for Service-Oriented Architecture (SOA). [ citation needed ] The current release of Oracle Application Server, 10g R3, does not feature a metadata repository tier, relying instead on metadata repositories provided in previous releases. n Client tier -- Contains the web browsers for end users n Web tier -- Contains the Oracle HTTP Server and the Web Cache n Application server (app server) tier -- Contains the core Application Server 10g, plus ancillary products such as Oracle Application Server Portal 10g, Oracle Developer, Oracle Reports, and Oracle Forms Server n Database tier -- Contains the core Oracle Database, which may be a single instance or many instances defined to a Real Application Cluster (RAC) Identity management is a process to manage the security life cycle of networks entities. Responsible for the creation, deletion, suspension, and privilege modifications of user accounts. Single Sign-On user accounts A Single Sign-On user account is used to access applications (including Oracle Portal) with a single user name and password, rather than a user having to remember multiple user names and passwords and log in to each application individually. Once a user has entered his or her Single Sign-On user name and password for one application, he or she can access other applications without having to log in again.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
