The Ant target for starting a WebSphere Application Server for z/OS server is startserver and requires the following options:
Important: Before starting the application server for the first time you must have run the database target followed by the prepare.application.data target. Failing to run this sequence will likely result in transaction timeouts during first login and a failure to initialize and access the application. Whenever the database target is rerun (e.g. in a development environment) the prepare.application.data target must also be rerun.
