Note:
  1. For monitor ID X'20', the user data field will provide the EBCDIC subchannel write device unit address associated with this device. Users should monitor this device for capacity issues.
  2. For monitor ID X'21', the user field will provide the EBCDIC subchannel read device unit address associated with this device. Some devices can configure how much read storage is used (for example, QDIO devices).
  3. Storage associated with DLC monitor IDs can be influenced by both SNA and TCP/IP workloads.
  4. This monitor ID is associated with a common service provided by z/OS® Communications Server, but is primarily associated with TCP/IP functions and application workloads.
  5. For TCP/IP inbound processing, a single buffer is used for many datagrams. The message triples are used to keep track of the datagrams. These message triples are used with DUPB operand.
