Interview Question for SOA-Part-II

1) What all components/Products needs to be installed before we Install Oracle SOA Suite tool ?.
 Following components needs to be installed before we install Oracle SOA Suite.
1. JDK
2. Database
3. All Required Schema (Created using RCU)
4. WebLogic Server

2) Which application server required for Oracle SOA Suite tool ?
Mostly WebLogic server is used as application server for Oracle SOA Suite tool.

3)Which IDE we use for Oracle SOA Suite tool ?.

 We use JDeveloper IDE for Oracle SOA suite tool.

4) What is domain ?.
 A domain is the basic administration unit for WebLogic Server instances. i.e. Domains include a special WebLogic Server instance called the Administration Server, which is the central point from which you configure and manage all resources in the
domain.

5) What is Administration Server ?
 A domain has one WLS instance configured as an admin server. The admin server provides a central point for managing a domain.

6) What is Managed Servers ?
 All other WLS instances in a domain are called Managed Servers. Managed servers host application components and resources.

7) What is Cluster ?
 Cluster is a group of server instances that work together as a single runtime unit from a client perspective. Clustering provides scalability and high availability for applications.

8) What is EM ?

 EM stands for Enterprise Manager. It is webpage we deploy, test, monitor, diagnose and resolve problem for composites. It is hosted on the Admin Server.

9)What is soa-infra ?
 soa-infra is a J2EE application that is targeted to either a managed server or a cluster. All the composites gets deployed under soa-infra application.

10)What all schema we need for Oracle SOA Suite tool ?.
 We require following schema.
1. MDS – This schema is used to store all the artifacts like WSDL, XML, XSD etc.
2. SOA_INFRA – This schema is used to store SOA Component Engine properties, deployed composites, payloads, runtime metadata etc.
3. ORABAM – This schema is used to store the metadata that is related to BAM and its components and this is optional schema.
4. ORASDPM – This schema is used to store metadata about the user messaging systems.

11) What is partition ?.
Sections of the SOA Infrastructure where we deploy SOA composite applications known as partition. When we install SOA suite tool, default partition get created with name “default” but we can add as many as partitions as required.

12) What are benefits of partition?
 Below are the major benefits of partition.
1. Logically group SOA composites.
2. Perform bulk lifecycle management tasks on large numbers of composites.

13) What all bulk operations we can perform on partition ?.
 We can perform below operations.
1. Start all composites
2. Shut down all composites
3. Undeploy all composites
4. Retire all composites
5. Activate all composites
6. List all composites

14) How we can deploy composite to SOA server ?.

 There are different methods to deploy SOA composite to SOA server.
1. Through EM console
2. Directly from JDeveloper
3. Scripting (Ant, WLST etc.)

15) What is config plan ?.
 Config plan is used during composite deployment. This is a xml file where we specify the parameters that we want to replace while doing the deployment to next environment.

16) Can we have multiple composites with same name on SOA server ?.

Yes, we can have multiple composites with same name on SOA server but this is possible when we have composites with revisions.

17) If we have multiple composites on SOA server with same name then how composites run ?.

 If we have multiple composites with same name then only one composite will act as default composite which will run only. But we can go to EM console and make other composite default.
