[20210107]快速进入目录2.txt

--//以前写的链接如下：http://blog.itpub.net/267265/viewspace-2129448/=>[20161130]快速进入目录.txt
--//花了一个上午重新改写：
--//主要以前写的select VALUE from v$parameter where name='user_dump_dest'; 换成
--//select VALUE from v$diag_info where name='Diag Trace';
--//也发现以前写的许多不严谨的地方，做了一些改写。
--//前提条件是建立环境变量ORACLE_UNQNAME.
