ORA-07391: sftopn: fopen error, unable to open text file.

    今天在自己的环境中创建pfile报错了。

    环境是：OS:11.2.0.2 RAC，OS:RHEL 5.6

创建pfile，报ORA-01565这个是因为不能找到spfile。

查看spfile文件位置

创建pfile到/tmp空间下面，/tmp空间一般是所有用户都有w权限的
SQL> create pfile='/tmp/123.ora' from spfile='+data/power/PARAMETERFILE/spfile.257.795051357';
create pfile='/tmp/123.ora' from spfile='+data/power/PARAMETERFILE/spfile.257.795051357'

07391, 00000, "sftopn: fopen error, unable to open text file."
// *Cause:  Fopen library routine returned an error.
// *Action: Verify existence and permissions.


晕报了ORA-07391,这个是由于权限不对，换个目录正常
SQL>  create pfile='/home/oracle/123.ora' from spfile='+data/power/PARAMETERFILE/spfile.257.795051357';

File created.
