z/OS Console Display Commands

The z/OS console display command is used to get the information about an executing address space.

Using the console display commands, you can get the following information:
  • The started task or job name and the step name.
  • Whether the job is swapped in, swapped out, or non-swappable.
  • The user ID assigned to the job.
  • The started task or job number.
  • Numbers of the performance group, address space, and domain.

To check if the platform server is up and running, the console operator must type D A,jobname.

See the following sample for the console display:

Platform Server VTAM Tracing

z/OS console operators can turn the VTAM tracing facility on and off by using modify commands. For more information, see Appendix B. Running Traces.

The following DD statement must be included in the startup JCL to enable the tracing facility.

//VTAMTRAC DD SYSOUT=X

z/OS console operators can turn the SNA packet tracing facility on and off by using the following modify commands:
  • TRON: to start the SNA packet tracing facility.

    F MFTSTC,TRON

  • TROF: to stop the SNA packet tracing facility.

    F MFTSTC,TROF

Platform Server TCP/IP Tracing

z/OS console operators can turn the TCP/IP tracing facility on and off by using modify commands. The following DD statement must be included in the startup JCL to enable the tracing facility:

//TCPTRAC DD SYSOUT=X

z/OS console operators can turn the TCP/IP tracing facility on and off by using the following modify commands:
  • TCPTRON: to start the TCP/IP packet tracing facility.

    F MFTSTC,TCPTRON

  • TCPTROF: to stop the TCP/IP packet tracing facility.

    F MFTSTC,TCPTROF

Platform Server Node Tracing

z/OS console operators can turn the TCP/IP tracing facility on and off by using modify commands. The following DD statement must be included in the startup JCL to enable the tracing facility:

//TCPTRAC DD SYSOUT=X

z/OS console operators can turn the node tracing on for a particular node defined in the CONFIG by using the following modify commands:
  • TCPTRON: to start the node tracing facility.

    F MFTSTC,TCPTRON,NODENAME

  • TCPTROF: to stop the node tracing facility.

    F MFTSTC,TCPTROF,NODENAME
