No actions are required to request a SYSIOS trace. Minimal and
unexpected event tracing is activated during IOS NIP processing and
is always active. In addition to this tracing, the user can request
a SYSIOS trace using specific options by doing the following:
- Using a CTnIOSxx SYS1.PARMLIB member during NIP processing by
specifying the CTRACE(CTnIOSxx) statement in the IECIOSxx SYS1.PARMLIB
member.
- Using a CTnIOSxx SYS1.PARMLIB member after NIP by issuing the
TRACE system command.
- Using the TRACE system command and specifying the options in response
to the prompts that CTRACE provides.
