application. Because SQL*Trace can analyze all SQL statements executed by an application or by the entire instance, I can use it to analyze the entire application as it runs. How do I use SQL*Trace and TKPROF to analyze queries?<p><B>Technique</B><p>SQL*Trace writes a file containing performance statistics. The volume of SQL*Trace output can be huge and the utility can adversely affect database performance so DBAs and developers should use it with care. There are four initialization parameters you can set to control SQL*Trace抯 behavior; they appear in Table 14.6.<p>Table 14.6 Initialization parameters that control SQL*Trace<p><table cellpadding=3 cellspacing=3 border=0 bgcolor="cdcdcd"><tr><td>Parameter</td><td>Setting</td><td>Description</td></tr>⌨️ 快捷键说明
