For information about starting and stopping a Component Trace External Writer and to connect or disconnect the writer from a component trace component, see the IBM guide, z/OS MVS System Commands (located under TRACE CT).
A sample PROC, CCIXWTR, is provided in CAI.CAW0PROC, which invokes the IBM external writer ITTTRCWR. For editing, see the IBM guide Diagnostic Tools and Service Aids. The PROC must be available for the MVS operator command TRACE CT. You may need to place PROC in SYS1.PROCLIB, IEFJOBS, or IEFPDSI.
Component Trace provides for automatically generating a TRACE CT command when component tracing is initialized. This action is performed using a PARMLIB member that can be specified on the CCICT control statement to initialize component tracing. The PARMLIB member can indicate that the TRACE is set ON, define and connect an External Writer, select ASIDs and JOBNAMEs for tracing, and specify OPTIONS.
A sample member, CTECCI00, 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 CCICT control statement. As delivered, if CCICT is added as a CAICCI parameter, CTECCI00 is used. Also, as delivered, CTECCI00 tells component trace to start the CCIXWTR started task. The CCIXWTR task must be customized to use a particular default output CTRACE data set.
CTECCI00 also sets TRACE ON, connect to its CCIXWTR External Writer, and collect trace records from all CAICCI applications for all currently defined Event IDs.
