Oracle无法启动，ORA-01034、ORA-01078

因为调整32位系统的SGA区大小时不慎，超出可用内存，造成Oracle实例无法启动，报出ORA-01034、ORA-01078等错误。如下图

sqlplus /nolog

SQL> conn / as sysdba

Connected.

SQL> startup;

出现错误：ORA-01078: failure in processing system parameters

ORA-01565: error in identifying file '/oracle/product/10.2.0/db_1/dbs/spfileorcl.ora'

解决办法

sqlplus /nolog

SQL> conn / as sysdba

Connected.

SQL> create spfile from pfile='/oracle/product/10.2.0/admin/orcl/pfile/init.ora';

创建后，在/oracle/product/10.2.0/db_1/dbs/ 重新生成 spfileORCL.ora

启动数据库

cmd> sqlplus /nolog

SQL> conn / as sysdba

Connected.

SQL> startup;

启动成功!
