This dual-layer instrumentation generates a unified trace file that isolates the exact SQL query causing application latency.&nbsp;<\/p>\n\n\n\n<p>Executing a step-by-step guide to trace an OAF page action down to the database SQL query requires strict adherence to initialization parameters. Use the following threshold logic to govern trace deployment:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Condition A:&nbsp;<\/strong>IF user session latency &gt; 5000ms, THEN set&nbsp;FND: Debug Log Level = Statement&nbsp;(Level 1).&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Condition B:&nbsp;<\/strong>IF database wait events are suspected, THEN execute&nbsp;DBMS_MONITOR.SESSION_TRACE_ENABLE&nbsp;with&nbsp;waits=true&nbsp;and&nbsp;binds=true.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Capacity Threshold:&nbsp;<\/strong>Trace file size &gt; 500MB = HIGH RISK.

This mapping allows database&nbsp;administrators to interpret TKPROF output accurately and pinpoint the exact PL\/SQL package degrading user experience.&nbsp;<\/p>\n\n\n\n<p>The process for correlating FND_LOG_MESSAGES with database trace files begins in the application UI.
