The CICS asynchronous API provides a simple, supported way to improve efficiency and reduce response times via asynchronous processing. For system administrators, the API affords a great opportunity to improve performance, and using CICS policy, you can gain even finer control over the the parent and child tasks in your system. CICS policy CICS policy...

The API enables developers to easily incorporate programming logic that follows a ‘parent-child’ model in their applications. This can be used to create more responsive applications, as it allows for workloads to run concurrently.
This article discusses how CICS TS V5.4 utilises the z/OS WLM health API (IWM4HLTH) as a means of controlling the flow of work into a CICS region at startup and shutdown.
