This action defines whether AT-TLS is enabled, allows trace settings, and provides the ability to set unique Language Environment® variables for the Language Environment process that will be started for the action. Many TTLSRule statements can reference the same TTLSGroupAction statement. In a simple implementation of AT-TLS, you need to specify only TTLSEnabled ON on the TTLSGroupAction statement.
The AT-TLS group action represents a single Language Environment process and enclave, and initializes one instance of the System SSL DLL. Global attributes are owned by this action. Each AT-TLS group has a main task, a logging task, and a dynamic pool of pthreads that handle System SSL secure environment and secure connection management. When a stale group has no remaining connections, the pthreads, tasks, and Language Environment process are removed.
