Overview of this book

WSO2 Enterprise Integrator brings together the most powerful servers provided by the WSO2 company for your SOA infrastructure. As an Enterprise Service Bus (ESB), WSO2 Enterprise Integrator provides greater flexibility and agility to meet growing enterprise demands, whereas, as a Data Services Server (DSS), it provides an easy-to-use platform for integrating data stores, creating composite views across different data sources, and hosting data services. Using real-world scenarios, this book helps you build a solid foundation in developing enterprise applications with powerful data integration capabilities using the WSO2 servers. The book gets you started by brushing up your knowledge about SOA architecture and how it can be implemented through WSO2. It will help build your expertise with the core concepts of ESB such as building proxies, sequences, endpoints, and how to work with these in WSO2. Going further, you will also get well-acquainted with DSS data service concepts such as configuring data services, tasks, events, testing, and much more. The book will also cover API management techniques. Along with ESB and DSS, you will also learn about business process servers, the rules server and other components that together provide the control and robustness your enterprise applications will need. With practical use cases, the book covers typical daily scenarios you will come across while using these servers to give you hands-on experience.

Tasks Scheduling

In this chapter, we will focus on the options we have for scheduling tasks inside the Enterprise Integrator server. The task scheduler is an important mechanism in integration scenarios because it gives us the opportunity to perform some actions automatically and at specific times. It will be very useful for launching big services that consume huge amounts of the server's resources; however, it will not be possible to execute it when there are final users consuming other services on the same server, because the server will have low performance. To remedy this, we can create a scheduled task for these types of service and execute it when the server is idle, at midnight for example.

In the Enterprise Integrator, we have three different types of scheduled tasks:

  • DSS task
  • ESB task
  • Custom task

In this chapter, we will see the differences between them and the...
