    Diffrence between infra tier-http and mid tier-HTTP -OAS

    user9256814

      Hi Team,

      I am new to the oracle application server administration(OAS). We have OAS server  in which both infra and mid-tier installed.

      HTTP_Server, OC4J instance  is running in both infra-tier and mid-tier.

      can we have HTTP,OC4J in both tier?

      I want to understand what is the use of having these services in both tier?Can anyone please make me understand in simple way.

       

      Thanks.

          Infra tier is the Database of your environment.

          Middletier is the "application server" and others processes that running your java applications, bpel applications, and so on. In 10g the middleware has OAS (Oracle Application Server), and in 11g the middleware has WebLogic.
