Oracle 用户 Trace 文件路径

下面载录几个和我写的一个。

--网上的一些解答:

Select c.Value || '/' || d.Instance_Name || '_ora_' || a.Spid || '.trc' Trace

From V$process a, V$session b, V$parameter c, V$instance d

Where a.Addr = b.Paddr And b.Audsid = Userenv('sessionid') And c.Name = 'user_dump_dest'

/disk/oracle/admin/study/udump/study_ora_13015.trc

Select u_Dump.Value || '/' || 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');

/disk/oracle/admin/study/udump/study_ora_13015.trc

Tom kytes:

Select c.Value || '/' || Instance || '_ora_' || Ltrim(To_Char(a.Spid, 'fm99999')) || '.trc'

From V$process a, V$session b, V$parameter c, V$thread c

Where a.Addr = b.Paddr And b.Audsid = Userenv('sessionid') And c.Name = 'user_dump_dest'

/disk/oracle/admin/study/udump/study_ora_13015.trc

Select P1.Value || '/' || P2.Value || '_ora_' || p.Spid || '.trc' FileName

From V$process p, V$session s, V$parameter P1, V$parameter P2

Where P1.Name = 'user_dump_dest' And P2.Name = 'db_name' And p.Addr = s.Paddr And s.Audsid = Userenv('SESSIONID');

/disk/oracle/admin/study/udump/study_ora_13015.trc

从SQL 长度上来看Tom 的最短，我认为最好。
