You can check the status of package using rpm -q command. This includes following steps.ġ) Check the required packages are installed in OS or not. Installing Oracle Application server 10g R2īefore starting the installation, we should complete the pre-installation checks. Having this brief knowledge above AS 10g R2 components, lets start with installation. So infrastructure tier contains mainly meta data repository and identity management. Out of the above components of infrastructure tier SSO, OID, DAS and OCA are together called as IDM (Identity Management). So infrastructure tier includes following components The other components shown in blue + OHS on right side are installed as infrastructure tier.

So its important that we first install infrastructure tier before installing mid tier, in case we want to go for option 2 or 3 for mid tier. This is because these middle tier component such as portal and wireless will create there own repository in infrastructure’s meta data repository. If we are installing either option 2 or 3, we have to install infrastructure tier before installing these mid tier components. However we can still install infrastructure tier but in this case it wont be used by these 3 components of mid tier. If we are installing just option 1 (J2EE and Web Cache) then infrastructure tier is not required. Business Intelligence and Forms (This will install all components).
Portal and Wireless (This will install all components of J2EE and Web Cache + Portal and Wireless components).J2EE and Web Cache (This will install Web Cache, OHS and OC4J).While installing this middle tier, the installation of these components are divided into 3 main components. All these components are categorized as given below.Īll the components shown in green color + OHS for mid tier (on left) + Web cache is installed as mid tier components. This shows what are the components that are present in AS (Application Server) and why those are required.Īll the above components shown above comes with AS 10g R2 installation. In case of 3 tier architecture performance is not an issue and is handled well in Application server.īelow is a very simple line sketch of application server 10g component architecture. This is in addition to database performance issue. Since all business logic gets executed at client side, performance on client reduces. The connection between client and mid tier is http which is a stateless connection.ģ) Performance is another factor which make 3 tier architecture a better solution over 2 tier architecture. As soon as data is provided the connection is closed. Where as in 3 tier architecture we have TCP/IP connection only between mid tier and database and is set when client request for some data. This increases network traffic and reduces bandwidth. So even if data is been send or not connection will always be there. So management is easy.Ģ) It reduces the network traffic, because in case of 2 tier architecture the protocol used is TCP/IP which is a stateful connection (continuous). Where as in case of two tier architecture ever client needs to be changed. Below is the three tier architecture show.ġ) In case of change in business logic the change needs to be done only in Application server (mid tier) as its centralized. Hence such clients are called as think client. Where as in case of multi tier architecture we have only presentation layer in client side and business logic is handled by Application server. In case of a two-tier architecture we business logic and presentation is both handled by client. Below is the difference between a two-tier architecture and multi-tier architecture. Purpose of Application server is to handle the business intelligent and logic.
