CEA TSO/E address space manager components

The CEA TSO/E address space manager ships with the common event adapter (CEA) component of z/OS®. The CEA component provides the framework and manages the resources for the TSO/E address spaces started using the CEA TSO/E address space manager. Table 1 describes the components included in the CEA TSO/E address space manager.

Component	Description
CEA address space	The CEA TSO/E address space manager is integrated into the CEA address space infrastructure. The function is started automatically when CEA is started. Attention : If the CEA address space ends, all the TSO/E sessions created by CEA will also end. Callers will not be notified that the CEA address space has ended. Instead, when a caller attempts to invoke the CEA TSO/E address space services or use the z/OS UNIX message queue, the request will fail.
Session table	When the CEA TSO/E address space manager starts a new TSO/E address space, the attributes of the address space and the resources obtained are stored in an internal session table. The entry exists for the life of the session and is removed when the TSO/E address space ends. To display the contents of the session table, use the `MODIFY CEA,DIAG,SESSTABLE` command. For more details about the command, see the topic about displaying the CEA TSO/E address space information in &ieag100t;.
z/OS UNIX message queue	The CEA TSO/E address space manager creates and manages a z/OS UNIX message queue, which is used to facilitate communication between the caller and the TSO/E address space. For more information about the z/OS UNIX message queue, see Communicating with programs running in the TSO/E address spaces.
CEATsoRequest API	The CEA TSO/E address space manager provides the CEATsoRequest API, which is a 64-bit C-language based API that callers can use to request TSO/E address space services. For more information about the API, see Using CEA TSO/E address space services.
