The Common Event Adapter (CEA) address space must be active to allow the z/OS UNIX-only services of BCPii to operate. CEA has two modes of operation: minimum or full-function mode. If the z/OS UNIX-only services of BCPii are required to be available, CEA must be running in full-function mode. To activate full-function mode, a set of security product definitions are required. See z/OS Planning for Installation for more information about how to configure Common Event Adapter for full-function mode.

CEA, like BCPii, starts as part of a system IPL. It can be stopped and restarted as well. See z/OS Planning for Installation for more information.
