Integrated Messaging Layer Deployment Pattern Pattern Description:

Integrated Messaging Layer is most common pattern in deploying the Oracle SOA Components and JMS Infrastructures. This pattern is applicable to small and medium size Fusion Middleware deployments where the JMS messages process is least or minimally used and does not require a complex setup of file systems and hardware. Queue based communication is least in this pattern and it is also applicable for setting up non prod environment in cases where JMS message is used heavily in Production.

Applicable Components: JMS and Oracle SOA Components in same Weblogic Runtime and they share the memory for process the SOA Process request and JMS Messages. This pattern is applicable when Oracle JMS is chosen as Service Messaging Layer.

Architecture (Deployment Style) Measurement Parameters:

Parameter Comments

Scalability Implementing the SOA Infrastructure using this pattern is less scalable compared to other patterns to follow. If JMS or SOA Processes require more memory for process than the predicted amount during the implementation it may not be able scale-up higher due fight for resources constraints.

Maintainability Easily maintainable due to less over-head in the architecture and less redundant nodes.

Reliability Reliability of message delivery is higher in this pattern as JMS and SOA Components are deployed in same web-logic runtime. Additional overhead in configuring SFAs (Store and Forward Agents) not required in this case

Availability SOA and JMS are always available as these components run together on same Weblogic runtime.

Performance Performance could be lower when messages of huge size and heavy process requirements are introduced by the end applications. SOA Processing power could be reduced due to this.

Caution: This Pattern is recommended for Development and Test Environments. Implementing this style of deployment for Production needs to be carefully sized for future growth of the message persistence needs and SOA Process.

Isolated Messaging Layer Deployment Pattern Pattern Description:

Isolated Messaging Layer is specialised pattern in deploying the Oracle SOA Components and JMS Infrastructures. This pattern is applicable to medium and large size Fusion Middleware deployments where the JMS messages process is heavy used and. Queue based communication is maximum in this pattern and it is also applicable for setting up prod environment.

Applicable Components: JMS and Oracle SOA Components in different Weblogic Runtime and they don’t share the memory to process the SOA Process request or JMS Messages. This pattern is applicable when Oracle JMS is chosen as Service Messaging Layer.

Architecture (Deployment Style) Measurement Parameters:

Parameter Comments

Scalability Implementing the SOA Infrastructure using this pattern helps to scale your SOA Infrastructure in multi-fold. If JMS or SOA Processes require more memory for process than the predicted amount during the implementation it possible for scaling up higher by adding additional hardware and memory to the respective machines in which they are hosted. Weblogic also provides options to tune JMS server for optimal process as it will not interrupted by other processes

Maintainability Increases the cost in maintenance as this pattern utilizes different hardware and infrastructure for hosting the JMS and SOA Components.

Reliability Reliability of message delivery is still higher in this pattern as JMS and SOA Components. SFAs (Store and Forward Agents) can be used if required to forward the message between different server sites.

Availability As SOA Components and JMS components run on two different runtimes; they could be possibility either one of them is not available; however high availability architecture can be utilized to make them always available.

Performance Performance of SOA and JMS Services can be scaled and tuned independent of each.

Caution: This Pattern requires additional and complex setup of file systems and hardware for JMS Message Processing.
