Specifying trace options after initialization

After TCP/IP or Telnet initialization, you must use the TRACE CT command to change the component trace options. Each time a new component trace is initiated, all prior trace options are turned OFF, and the new traces are activated.

You can specify the TRACE CT command with or without the PARMLIB member.

You can use IBM® Health Checker for z/OS® to check whether TCP/IP Event Trace (SYSTCPIP) is active with options other than the default options (MINIMUM, INIT, OPCMDS, or OPMSGS). For more details about IBM Health Checker for z/OS, see IBM Health Checker for z/OS.
