The thread log traces the history of when threads start, as well as how many times a thread has failed and been restarted by Thread Manager. By default, the log file is named arthread.log.
Each transaction begins with the <THRD> prefix, followed by an RPD Id and a time stamp. Following the time stamp is a detailed information about the thread.
The format for the thread log file is as follows:
<THRD> <RPCId> /* <ddd mmm dd yyyy hh:mm:ss:nnnn> */ Thread Id <threadID> (thread number <threadNumber>) on <queueType> <tStatus>.
The following table explains the possible values for the entries in a thread log file.
