Trace options

These options are available for use with the MVS™ system command /F <JOB_NAME>,APPL=TRACE.

To get help on these options, issue the following command:
/F <JOB_NAME>,APPL=TRACE,?
Option Short form Description
DUMPOFFSET =integer OF=integer Specifies the offset from which displays of any data blocks start, for example 512. If the offset is greater than the total length of data to be displayed, an offset of 0 is used. This option applies only to the Gateway trace, not JNI trace.

You cannot use this together with the fulldatadump option.

FULLDATADUMP

FD Sets the dumpoffset to 0 and ignores any value specified in truncationsize. This option applies only to the Gateway trace, not JNI trace.
    Specifies the name of the output file for JNI tracing. You must specify a value for this option. If you do not, an error is displayed. JNI trace is output as plain text, and there is no requirement to use a particular extension for the file name.
JNILEVEL=0|1 JL
0
Off. No trace information is output.
1
On.
TFILESIZE =integer TS=integer Specifies the maximum size, in kilobytes, of the Gateway trace output file, for example 50000.
    Specifies the output file for Gateway tracing, for example ./tracefile.trc on UNIX and Linux or .\tracefile.trc on Windows. If you do not specify a value for this option, trace output is sent to the console.
TLEVEL =1|2|3|4 TL Specifies the Gateway trace level. Permitted values are:
0
Off. No trace information is output.
1
Exception tracing. Only exceptions are traced. See Options on the ctgstart command.
2
Trace exceptions, and entry and exit of methods.
3
Trace exceptions, some internals, and entry and exit of methods.
4
Full debug tracing (all trace points).

TRUNCATIONSIZE =integer

TR=integer Specifies the byte at which to stop the hex dump, for example 2000. It defines the end point, not the number of bytes to display. So if on a dump of size 40 you set the dumpoffset to 11, and the truncationsize to 25, you will see 15 bytes (from 11 to 25).

You cannot use this together with the fulldatadump option. This option applies only to the Gateway trace, not JNI trace.
