TRACE Command
{ keyword }
{ ( keyword [ , keyword ]... ) }
where keyword is one or more of the following values:
[ ALL ]
[ MSG ]
[ L4 ]
[ L3 ]
[ NETIO ]
ALL [or blank]
(or blank) specifies that all trace options are selected. This is the default value.
The trace file can get very large very quickly. It will wrap, if requested, or will
simply stop tracing when the TO file gets full.
MSG
specifies tracing of messages from and to $RECEIVE.
L4
specifies tracing of Transport Layer related activity.
L3
specifies tracing of Network Layer related activity.
NETIO
specifies tracing of subnetwork IOP interface activity.
TO file-spec
specifies the file to which trace information is to be written. The file might have
been previously created as an unstructured file with file code 830. An old file is
purged of data before the trace is initiated. If the file does not exist, SCF creates the
file with an extent size of 100 pages for the primary extent and 20 pages for
secondary extents. There are a maximum of 15 secondary extents for a maximum
file size of 400 pages. If a file larger than 400 pages is needed, use a previously
created file.
WRAP
specifies that when the trace disk file end-of-file (EOF) is reached, trace data will
wrap around to the beginning of the file and overwrite any data that is there. The
default is “NOWRAP.”
