Driving IBM Z Workload Scheduler with REST API

IBM® Z Workload Scheduler provides a set of fully functional APIs that are implemented based on Representational State Transfer (REST) services. The REST API helps you easily integrate workload scheduling capabilities with external products and solutions. The same product functionality covered by the existing J2EE API is available with the REST API. The REST API is programming language independent and favors easier network configuration and firewall traversal. With the APIs, you can exploit heterogeneous environments and provide new automation opportunities with direct impact on productivity. The following are some examples or scenarios where the APIs can be implemented:

• Create your own graphical interface to create and modify scheduling definitions and update objects in the plan.
• Update definitions or plan objects within a script for integration or automation.
• When a specific event occurs within an external product, you can automatically submit a batch workload through IBM Z Workload Scheduler.
• In a managed file transfer solution, when a specific file arrives, you can submit one or more job flows that elaborate the file, closing the loop on your business process, whether it be bank transactions, a payroll process, or report generation. Your external managed file transfer product starts the business process and IBM Z Workload Scheduler takes care of the processing, assuring that it be monitored with the rest of the processes from a single point of control and eventually linked with other processes.

After installing the Z connector, you can access the available REST API services by connecting to the following URL:

https://hostname:port_number/twsz

where:

hostname

Host name of the Z connector.

port_number

HTTPS port number of the Z connector. The default is 9443.
