CTncccxx (component trace parameters)

Use the CTncccxx parmlib member to specify tracing options for a component trace of either an MVS™ component or an application. The specific tracing options for those MVS components that support component tracing can be found in z/OS MVS Diagnosis: Tools and Service Aids. For tracing options for non-IBM supplied applications, refer to the documentation for those applications.

The CTncccxx parmlib member is specified as an 8-character member in the following format:
CT
Indicates that the member contains component trace options
n
Specifies the source of the member. IBM-supplied members use “I”.
ccc
Identifies the component being traced.
xx
Any two alphanumeric characters.
The CTncccxx parmlib member is specified on:
  • The CTRACE macro (with the DEFINE parameter)
  • The TRACE CT operator command
  • The parmlib member for some IBM-supplied components.
