Use the DB2® START TRACE and STOP TRACE commands to trace DB2 system activity. You can tailor these commands to trace specific application plans or all application plans. You can record the output of the trace using the generalized trace facility (GTF), remote entry services (RES), or system management facilities (SMF). For more information on the DB2 trace, refer to IBM Information Management Software for z/OS Solutions Information Center at http://publib.boulder.ibm.com/infocenter/dzichelp/v2r2/index.jsp.
