4-12 Oracle Fusion Middleware Developers Guide for Oracle Data Integrator b. Select or type the Work Schema for this Data Integrator physical schema in ... Work Schema . A list of the schemas appears if the technologies supports schema listing.

3. Check the Default box if you want this schema to be the default one for this data

server The first physical schema is always the default one.

4. Go to the Context tab.

5. Click Add.

6. Select a Context and an existing Logical Schema for this new Physical Schema. If no Logical Schema for this technology exists yet, you can create it from this Editor. To create a Logical Schema: 1. Select an existing Context in the left column. 2. Type the name of a Logical Schema in the right column. This Logical Schema is automatically created and associated to this physical schema in this context when saving this Editor.

7. From the File menu, click Save.

4.2.4 Creating a Logical Schema

To create a logical schema:

1. In Topology Navigator expand the Technologies node in the Logical Architecture

accordion. 2. Select the technology you want to attach your logical schema to.

3. Right-click and select New Logical Schema.

4. Fill in the schema name.

5. For each Context in the left column, select an existing Physical Schema in the right column. This Physical Schema is automatically associated to the logical schema in this context. Repeat this operation for all necessary contexts.

6. From the File menu, click Save.

4.2.5 Creating a Physical Agent

To create a Physical Agent: 1. In Topology Navigator right-click the Agents node in the Physical Architecture accordion.

2. Select New Agent.

3. Fill in the following fields: ■ Name : Name of the agent used in the Java graphical interface. ■ Host : Network name or IP address of the machine the agent will been launched on. ■ Port : Listening port used by the agent. By default, this port is the 20910. ■ Web Application Context : Name of the web application corresponding to the Java EE agent deployed on an application server. For standalone agents, this field should be set to oraclediagent. Setting-up the Topology 4-13 ■ Protocol : Protocol to use for the agent connection. Possible values are http or https. Default is http. ■ Maximum number of sessions supported by this agent. 4. If you want to setup load balancing, go to the Load balancing tab and select a set of linked physical agent to which the current agent can delegate executions. See Section 4.3.3.3, Setting Up Load Balancing for more information.

5. If the agent is launched, click Test. The successful connection dialog is displayed.

6. Click Yes.

4.2.6 Creating a Logical Agent

To create a logical agent: 1. In Topology Navigator right-click the Agents node in the Logical Architecture accordion.

2. Select New Logical Agent.

3. Fill in the Agent Name.

4. For each Context in the left column, select an existing Physical Agent in the right column. This Physical Agent is automatically associated to the logical agent in this context. Repeat this operation for all necessary contexts.

5. From the File menu, click Save.

4.3 Managing Agents

This section describes how to work with a standalone agent, a Java EE agent and how to handle load balancing.

4.3.1 Standalone Agent

Managing the standalone agent involves the actions discussed in these sections: ■ Section 4.3.1.1, Configuring the Standalone Agent ■ Section 4.3.1.2, Launching a Standalone Agent ■ Section 4.3.1.3, Stopping an Agent

4.3.1.1 Configuring the Standalone Agent

The odiparams file is a configuration script that contains the parameters for the Oracle Data Integrator standalone agent command line scripts. It contains the repository connection and credential information for starting the standalone agent. It is necessary to have this configuration done before starting a standalone agent. This file is in the agentbin directory of the Oracle Data Integrator installation directory. Note: The agent command line scripts, which are required for performing the tasks described in this section, are only available if you have installed the Oracle Data Integrator Standalone Agent. See the Oracle Fusion Middleware Installation Guide for Oracle Data Integrator for information about how to install the Standalone Agent.
