原因和解决办法：
The Unix permissions for the hidden directory /tmp/.oracle should be:
Owner = the Oracle user who performed the database install,
Group = the dba group of the Oracle user,
and the directory's Unix permissions should be drwxrwxrwx
目录/tmp/.oracle的权限应该是：
owner = 执行数据库安装的oracle用户，
group = oralce用户的dba组，
而且这个目录权限应该是 drwxrwxrwx
Change the permissions on the .oracle directory:
1) cd /var/tmp（on Solaris Linux） or /tmp（on Hp and IBM）
2) Change the ownership and group of the ".oracle" directory to "oracle/dba":
# chown -R oracle:dba .oracle
or
3) Change the permissions on the directory:
# chmod 777 .oracle
执行 dbca 也得用oracle身份去,不然也会出现一系列权限的错误
