A text trace file is the default format when a trace is run.
To control the behavior and the appearance of the file, set the following TEXTFILE emitter properties in the Consolidated Tracing Facility configuration file:
Property | Description | Default |
---|---|---|
DELIMCHAR | The character used in the output file to delimit trace data parts for a trace event. | SPACE |
FILE | The name of the trace file to be written. You can use the following pseudo-variables for the construction of the trace file
name:
|
$(APPNAME).$(EMITTER).$(PID).log, or
$(APPNAME).$(EMITTER).$(PID).log_$(GEN) if the MAXGENERATION property has been specified. For example:
|
FLUSHEVERY | The number of trace records that will be output before the file is flushed. 0 indicates that the file will never be explicitly flushed. | 1 |
FORMAT | The format to be used for each trace data record written to the file. You can use the following pseudo-variables in the format
specification:
|
$(TIME) $(COMPONENT) $(EVENT) $(LEVEL) $(DATA) |
HEXBLOCKSIZE | The number of hexadecimal bytes to be output in each block when outputting binary trace data. Each block of hexadecimal characters
will be separated by a '-' character. For example, if HEXBLOCKSIZE is set to 4, and some binary trace data with the value
3132333435363738393A3B3C3D3E3F is specified for output, it would be formatted as follows:
31323334-35363738-393A3B3C-3D3E3F |
8 |
LOCATION | The folder where the trace files are to be written. This is used when a trace file is created. |
If the folder specified by the LOCATION property does not exist, the Consolidated Tracing Facility tries to create it. If this fails, the Consolidated Tracing Facility uses the default location (as specified by the MFTRACE_LOGS environment variable). If this fails, the current folder is used. |
MAXFILESIZE | The maximum amount of data (in KB) that will be written to the trace file before the file is closed and the next trace file
in the generation sequence is opened. The first trace file in a generation sequence results in the $(GEN) pseudo-variable
(see the description of the FILE property, above) being set to 1, the second in the sequence results in it being set to 2,
and so on until MAXGENERATION is exceeded. Once the MAXGENERATION number of files has been reached, the generation number
reverts to 1 and the first trace file in the generation is overwritten.
This is only used if MAXGENERATION > 1. |
10000 (KB), with a maximum file size of 1000000 KB. |
MAXGENERATION | The maximum number of trace files that will be written to while tracing is enabled. Use this property in conjunction with the MAXFILESIZE property. The maximum value is 100. | 1, indicating that only a single trace file will be created. |
MultiProc | Controls whether trace events are written to the trace file by a single process or multiple processes. If enabled for multiple
processes, the
File property must also be specified without the
$(PID) pseudo-variable embedded in its name.
if $(RUNUNIT), $(RUNUNIT_SESSIONNAME), or $(RUNUNIT_GUID)" is used, the file name will be unique, therfore MultiProc is not required (applies to .JVM COBOL only) |
FALSE, indicating that the configured trace file includes only events from the current process |
QUOTESTRING | Whether or not string trace data is to be output enclosed in double-quote characters. . | TRUE |
When using the MultiProc property, and two or more COBOL run-time systems (native or JVM) are executing in the same process, sharing the same trace file is not a performant configuration. Using the $(PLATFORM) variable in the filename allows you to use different filenames for different run-time systems. If tracing includes the $(PID) variable, you can safely set the MultiProc property to false. For example:
$(APPNAME). $(EMITTER).$(PID).$(PLATFORM).log
When a JVM COBOL application executes in a multi-user environment, the user of .NET RunUnits should be used. The default filename for both the TEXTFILE and BINFILE emitter collects all the trace events into one or more files. However, if the configuration property #file uses $(RUNUNIT), $(RUNUNIT_SESSIONNAME) or $(RUNUNIT_GUID), separate files can be created for each RunUnit. For example:
$(APPNAME).$(PLATFORM).$(EMITTER).$(RUNUNIT_GUID).log
or
$(APPNAME).$(PLATFORM).$(EMITTER).$(RUNUNIT).log
or
$(APPNAME).$(PLATFORM).$(EMITTER).$(RUNUNIT_SESSIONNAME).log
If a JVM COBOL application is executing in a permissions-restricted environment, use of the MultiProc property on the TEXTFILE emitter is not available.
