2.2.1 Initializing the Handler

The very first service request that is sent from the TMA TCP gateway running on a remote Oracle Tuxedo node causes the following to occur.

  1. CICS Sockets Listener starts the TMA TCP for CICS Handler
  2. Listener issues a givesocket() function call
  3. Handler issues a takesocket() function call
  4. Listener resumes listening for new connection requests
  5. Handler communicates directly with the remote TMA TCP gateway using TCP/IP
