TRACE Command
TRACE Command
The TRACE command is a sensitive command: The TRACE command:
•
Starts a trace operation on a ServerNet SAN manager process
•
Alters trace parameters set by a previous TRACE command
•
Stops a previously requested trace operation
The TRACE command syntax is:
OUT file-spec
causes any SCF output generated for this command to be directed to the specified
file.
TO file-ID
activates a trace and specifies the name of the file into which trace data is to be
collected.
This option is required when you are starting a trace operation.
If the file already exists, it is purged of data before the trace is initiated. If the file
does not exist, it is created with an extent size based on the value of the PAGES
parameter.
If TO is not specified, the existing trace is either stopped (if STOP is specified) or
modified as specified in the trace-option.
BACKUP
specifies that the backup process should receive the trace request.
COUNT records
specifies the number of trace records to be captured. The trace will terminate after
the number of records has been collected.
PAGES pages
designates how much memory space is allocated in the extended data segment
used for tracing. The trace will terminate after the number of pages of trace data
has been collected.
