CICS TCP/IP support

CICS® provides additional detailed information for those applications using the CICS Web support (CWS), CICS IIOP, and the CICS ECI over TCP/IP support.

The performance class monitoring data provided includes the following fields:
  • The TCP/IP service name and port number of the installed TCP/IP service resource definition from which the transaction was initiated
  • The Client IP address in the interpreted format of nnn.nnn.nnn.nnn
  • Inbound and outbound socket I/O wait times
  • Extract TCP/IP request counts
  • Inbound and outbound Socket request and character counts - send, receive, and so on

For detailed information on the data provided for the CICS support for TCP/IP, see section on the DFHSOCK group in the CICS Performance Guide.

CICS PA provides Transaction Group Detail and Summary reports to analyze the performance class data by transaction group ID.

CICS PA provides two sample Report Forms that you can use to tailor the Performance List Report (TCPLST Form) and Performance Summary Report (TCPSUM Form) for analyzing the performance class data for the CICS support for TCP/IP.

For more general information, see the CICS Internet Guide, the CICS External Interfaces Guide, and CICS Family: Communicating from CICS on System/390®.
