实验环境：

在完成软件升级界面的运行后，尝试打开数据库，出现报错如下：

SQL> select substr(comp_name,1,40) comp_name, status, substr(version,1,10) version from dba_registry order by comp_name;

select substr(comp_name,1,40) comp_name, status, substr(version,1,10) version from dba_registry order by comp_name

于是进入相关位置查验：

发现 '/u01/app/oracle/product/11.2.0.1/dbhome_1/dbs/initorcl.ora'文件并不存在，取而代之的是 '/u01/app/oracle/product/11.2.0.1/dbhome_1/dbs/initORCL10g.ora'
也就是说是环境中的SID设置有问题，需要将其修改为现文件所使用的名字。
修改后重启系统，即可解决报错：
