【Oracle】跟踪文件目录(User_Dump_Dest)生成脚本（11g/9i).txt

oracle 11g 生成跟踪目录(User_Dump_Dest)脚本：
–设置合适显示长度：
column trace new_val TRACE format a100
–脚本：

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'
/

–开启跟踪
exec dbms_monitor.session_trace_enable
–查看生成的跟踪文件目录
!ls &TRACE

例如：

SYS@ORA11GR2> column trace new_val TRACE format a100
SYS@ORA11GR2> 
SYS@ORA11GR2> select c.value || '/' || d.instance_name || '_ora_' || a.spid || '.trc' trace
  2      from v$process a, v$session b, v$parameter c, v$instance d
  3     where a.addr = b.paddr
  4       and b.audsid = userenv('sessionid')
  5       and c.name = 'user_dump_dest'
  6  /
