如何查看内核trace

oracle的trace文件路径是通过系统参数 user_dump_dest 参数来指定的。

可以通过以下方式查看：

1、 show parameter user_dump_dest

2、select * from v$parameter where name='user_dump_dest'

alter system set user_dump_dest='path' 可以修改参数

一般来说默认的trace路径是 $ORACLE_BASE/diag/rdbms/SID/SID/trace/

楼上说的不对，出的错与单引号无关，是编码的问题。你的代码本身没错，把你现在的文件删掉，重新建一个就行。下面和你的一样，只是换了路径，测试可行
