oracle 获取当前session的trace文件名

获取默认文件名SQL如下：

--第1种SELECT u_Dump.Value || '/' || Lower(Db_Name.Value) || '_ora_' ||       V$process.Spid ||       Nvl2(V$process.Traceid, '_' || V$process.Traceid, NULL) || '.trc' "Trace File"  FROM V$parameter u_Dump CROSS JOIN V$parameter Db_Name CROSS JOIN V$process  JOIN V$session    ON V$process.Addr = V$session.Paddr WHERE u_Dump.Name = 'user_dump_dest'   AND Db_Name.Name = 'db_name'   AND V$session.Audsid = Sys_Context('userenv', 'sessionid');--第2种SELECT d.Value || '/' || Lower(Rtrim(i.Instance, Chr(0))) || '_ora_' ||       p.Spid || '.trc' AS "trace_file_name"  FROM (SELECT p.Spid          FROM V$mystat m, V$session s, V$process p         WHERE m.Statistic# = 1           AND s.Sid = m.Sid           AND p.Addr = s.Paddr) p,       (SELECT t.Instance          FROM V$thread t, V$parameter v         WHERE v.Name = 'thread'           AND (v.Value = 0 OR t.Thread# = To_Number(v.Value))) i,       (SELECT VALUE          FROM V$parameter         WHERE NAME = 'user_dump_dest') d;

eg:

/data03/DEV4/db/9.2.0/admin/DEV4_mistest/udump/dev4_ora_9359834.trc
