External SFD interface functions

The behavior of the external SFD interface functions such as the DB2® interface or MQ interface is recorded in trace files that are stored in the following directories:

• dnitrace/xfsm/ltname/cli
• dnitrace/xfsm/ltname/srv

where dnitrace is a directory specified in the FTM SWIFT configuration file /etc/dni.conf. The default locations of the external SFD interface functions trace are:

/var/ftmswift_v300/run/trace/xfsm/ltname/cli
/var/ftmswift_v300/run/trace/xfsm/ltname/srv

The SFD process creates a set of 10 trace files for each client and for each server. Each time an LT is logged in, a new set of trace files is created. Each file requires approximately 4 MB. Therefore, an entire set of trace files for an LT requires approximately 80 MB. These files are used in a wraparound mode; that is, after the tenth file is filled, the first file is reused, and its contents are overwritten. The name of each trace file comprises a timestamp and the serial number of the trace file. The serial numbering begins with 00. For example, the trace file with the name 160101084910781546000_04.trc:

• Was created on 1 January 2016 at 8:49 and 10.781546000 seconds Coordinated Universal Time (UTC)
• Is the fifth file of this set
