Agent Types

1. Standalone Agents

• Definition: A standalone agent is a basic agent that runs independently on a server or machine.
• Key Characteristics:
• It does not share resources with other agents.
• Ideal for smaller environments or where there is no need for high scalability.
• Can be deployed on any machine capable of running Oracle Data Integrator.
• Setup:
• Standalone agents are installed on individual servers.
• They are configured separately for each server.

2. Standalone Colocated Agents

• Definition: A standalone colocated agent combines the functionality of a standalone agent but is colocated with the Oracle Data Integrator Studio or repository server.
• Key Characteristics:
• Colocation means the agent and the ODI Studio/repository are installed on the same machine.
• Typically used in environments where resource utilization and performance need to be optimized.
• This setup reduces network latency as it minimizes the communication between ODI components.
• Setup:
• During installation, the agent is configured to be colocated with the ODI Studio or repository.
• Ideal for environments with low to moderate workloads.

3. Java EE Agents

• Definition: Java EE agents are deployed in an enterprise environment where a Java EE (Enterprise Edition) application server is used.
• Key Characteristics:
• Scalability: Java EE agents are designed to work within a Java EE container (e.g., Oracle WebLogic, JBoss, or Apache Tomcat), allowing for better scalability.
• High Availability: These agents can be configured for clustering, load balancing, and failover, ensuring high availability.
• Typically used in large, distributed environments with significant processing demands.
• Setup:
• Java EE agents are installed and configured within a Java EE container.
• They require a full Java EE application server for their deployment.
• Can be scaled horizontally (more agents can be added to the Java EE container).

Summary of Key Differences

Agent Type	Deployment	Scalability	Use Case
Standalone Agents	Individual server	Limited scalability	Small to medium environments
Standalone Colocated Agents	ODI Studio/repository	Moderate scalability	Optimized resource usage, low to moderate workloads
Java EE Agents	Java EE application server	High scalability	Large, distributed environments with high processing needs

Key Considerations When Choosing an Agent Type:

1. Environment Size: Choose standalone agents for small environments and Java EE agents for large, high-demand systems.
2. Scalability Needs: For systems that need to scale, Java EE agents are the best choice.
3. Performance Optimization: Standalone colocated agents are ideal for improving performance in environments where ODI Studio and the agent are co-located.
