A few months ago we delivered z/OS Provisioning Toolkit, allowing you to bring up CICS regions in minutes, and purge them just as quickly. Being a command that’s run from USS—from a shell—z/OS PT is easy to use as part of a more complicated script. In this short example, we’re going to write a script to be able to remove all containers in the system older than x days. This can then be scheduled to run every night, to ensure developers don’t leave their CICS regions (or any other container contents) sat around unnecessarily. Treat your z/OS PT-created CICS regions like livestock, not pets, remember. All source code for this example is on CICSDev on GitHub.
