Refer to the IBM manual, z/OS MVS System Commands (located under TRACE CT) for information on starting and stopping a Component Trace External Writer and to connect or disconnect the writer from a component trace component. A sample PROC, ENFXWTR, is provided in CAI.CAW0PROC, which invokes the IBM external writer ITTTRCWR. Refer to the IBM manual Diagnostic Tools and Service Aids for editing. The PROC must be available for the MVS operator command TRACE CT. You may need to place PROC in SYS1.PROCLIB or IEFJOBS or IEFPDSI).
Component Trace provides for automatically generating a TRACE CT command when component tracing is initialized. This is performed via a PARMLIB member that can be specified on the IBM macro to initialize component tracing. A sample member, CTEENF00, is shipped in CAI.CAW0OPTN. If this member is used, it must be moved to an MVS PARMLIB data set and its name specified on the ENFCT auto command. As delivered if ENFCT is added as an CAIENF parameter, then CTEENF00 will be used and as delivered CTEENF00 will tell component trace to start the ENFXWTR started task. The ENFXWTR task must be customized to use a particular default output CTRACE data set.
