You can assign connector options by setting USYS$TCP_PARAMS in the [DRIVER_SETTINGS] section of the assignment file.

USYS$TCP_PARAMS = {ub=MaximumPacketSize} {,%\sb=MaximumSendBufferKB} {,%\rb=MaximumReceiveBufferKB} {,%\n=0|1} {,nl} {,%\prf=4|6} {,%\ql=QueueLength { , %\ka}

Options

  • ub (Uniface buffer)
  • sb (Send Buffer)
  • rb (Receive Buffer)
  • n (Nagling)
  • nl (No Linger)
  • prf (Version Preference)
  • ql (Queue Length)

TCP connector options enable you to tune the TCP connector performance.

The TCP connector creates the physical connection for both TCP/IP and TLS connections. When you set connector options for the TCP connector, these settings stay in effect for all TCP and TLS connections.
