在网上搜了半天，还在itpub上发了贴，半天都没有找到解决办法，只好决定自己再次
详细检查一下，结果发现是如下原因所致：
SQL> create or replace directory DUMPDIR
2as '/home/oracle/testdump/';
Directory created.
SQL> host ls /home/oracle/testdump
/home/oracle/testdump not found
创建文件夹/home/oracle/testdump 后，如上test.sh可以正确运行：
$ mkdir testdump
$ . /home/oracle/test.sh

可见，在sqlplus中创建DIRECTORY时，oracle并不检查引用的操作系统文件夹是否已经
存在，应该仔细检查。 [/B]
可以理解为那只是在sqlplus里创建一个变量,并为它赋值而已.至于那个值是否合理,它不会帮你去检查.
