数据库在安装完成后，在启动时，报错误：ORA-01078: failure in processing system parameters

SQL> conn /as sysdba;

ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file '/opt/oracle/product/10g/dbs/initnis.ora'
从上面报的错误不难看出是缺少了文件initnis.ora，于是执行cp /opt/oracle/admin/gaxt/pfile/init.ora.1122011151513 /opt/oracle/product/10g/dbs/initnis.ora
重新启动，
SQL> conn /as sysdba;
Connected to an idle instance.
SQL> startup
ORACLE instance started.

发现可以启动，上面的问题解决，但又报了一个错。解决方面请查我的另一篇日志：
