A.1.3 Trace Options

-t
When initiating the CRM from the UNIX command line, you can specify any of the following CRM trace levels using the -t option:
  • 0 = No tracing. Setting this level effectively disables CRM tracing and closes the trace file, if there is one. If tracing is subsequently restarted, a new file is created with an incremented numerical suffix.
  • 1 = Minimum tracing. At this level, CRM traces only major events and is sufficient only to determine the sequence of application conversations.
  • 2 = Medium tracing. At this level, CRM also traces all I/O buffers.
  • 3 = Maximum tracing. At this level, CRM also traces all APPC verbs.

    The APPC Stack API trace is either enabled or disabled using the -s option of the CRM command (refer to “General Options”). If enabled, it generally shows the parameters and results of all API calls. Depending on the stack being used, other options (such as vendor-specified environment variables) may have to be activated for CRM to enable the trace.

    Note:

    The time tag information in the CRM trace should reflect the current system time. In order to make use of the correct time zone information on UNIX and MVS systems, it is important that the TZ environment variable be set correctly. If this variable is not set correctly on your system, refer to your system documentation for further information.
-F
Saves the spool trace copy for feeding the utility crmretrc.
trcsz
Trace size. The value can be 10 - 2048 (M), and the default is 10.
