DBMS_SQLTUNE 系统包兼容Oracle 的DBMS_SQLTUNE 包的部分功能，提供一系列对实时SQL监控的方法。
当SQL监控功能开启后，DBMS_SQLTUNE 包可以实时监控SQL执行过程中的信息，包括：执行时间、执行代价、执行用户、统计信息等情况。使用DBMS_SQLTUNE 也需要将DM.INI 参数ENABLE_MONITOR、MONITOR_TIME、MONITOR_SQL_EXEC设置为1。
使用DBMS_SQLTUNE.REPORT_SQL_MONITOR 方法可以查看上述执行号为2411 的执行计划信息。
22:28:49 sysdba@DAMENG:5236 SQL> set long 100000 22:28:51 sysdba@DAMENG:5236 SQL> SELECT DBMS_SQLTUNE.REPORT_SQL_MONITOR(SQL_EXEC_ID=>2410);
以看到此方法获取的执行计划比ET 函数更详细。
DBMS_SQLTUNE.REPORT_SQL_MONITOR(SQL_EXEC_ID=>2410)
