All messages that a mainframe client sends or receives to the SQL Engine normally pass through the TDP. In addition to session, packet, and security control, mainframe TDPs are responsible for:

  • Balancing sessions across assigned parsing engines
  • Routing responses back to the originating address space

Also, you can request DBCTIME time stamps to record when:

  • The TDP receives the request.
  • The request was queued to the server.
  • The server received the response.
  • The response was queued to the cross-memory task.
  • The response was returned to the input (response) buffer of the user.
