When the auxiliary trace is activated, it writes binary data to the auxiliary trace file. This provides the fastest way to collect the data without impacting the application being traced.
The data is in a raw format, which is unreadable. The data must be formatted by the CA Gen ETFFMTX utility to convert the data to a usable, readable format.
A CLIST is provided to access the ETFFMTX utility. No panel interface is provided. The CLIST accepts two arguments that are used to define the auxiliary trace file and formatter parameters:
The auxiliary trace data is written to a file named tiupref.IEF.AUXTRACE.tiusufx, that can be formatted for diagnosis.
If you execute more than one auxiliary trace, rename the file to save it. The formatter can accept input from a file other than the standard file name. If the file is renamed, then the file name can be passed to the formatter through this argument. Otherwise, the formatter assumes the standard name.
When the auxiliary trace file was created from a background execution of the generator, the data set name format changes to: tiupref.BAT.Djhhmmss.IEF.AUXTRACE.tiusufx
j is the last digit of the Julian day number
hhmmss is the time that the file was created, in 2400-hour format
If the background execution, the data set name using this operand MUST be passed to the formatter.
The ETFFMTX utility accepts a wide range of arguments that are used to control the selection of events from the auxiliary trace file. These arguments can define selection filters, limits, and other mechanisms to limit the output to analyze a specific problem. The CMDLINE parameter collects these arguments as a string and passes them to the ETFFMTX utility.
