1.2 Oracle TMA TCP for CICS Architecture

Oracle TMA TCP for CICS is composed of four CICS programs running within a CICS region:
  • Handler
  • Application Handler
  • Pre-requester
  • Requester
It uses the Sockets Interface and Sockets for CICS Listener that is shipped with the IBM TCP/IP for CICS TS Sockets Interface. There are two different processing scenarios to consider:
  • Requests that originate in a remote Oracle Tuxedo domain and request services offered by CICS
  • Requests that originate in a CICS region and request services offered by a remote Oracle Tuxedo domain
