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.
