Bypass send and receive

For application-to-application sessions in the same host, ULTRAOPT lets you bypass VTAM for all SENDs and RECEIVEs for sessions that are created by a CLSDST PASS or a REQSESS (such as a session manager’s background sessions). This ability improves your response time and reduces the amount of CPU time that is used for these sessions. Bypass Send and Receive (BSR) sessions are not optimized because there is no need to optimize data that never leaves the system.

Some CPU usage is saved because

  • VTAM does not have to execute SENDs and RECEIVEs under those applications’ address spaces.
  • No optimization is necessary in the background applications’ address spaces.
