Oracle10.2.0.1到10.2.0.4升级，升级完成后，连接数据库时竟然出现了ORA-01092故障，导致无法打开数据库，现象如下： SQL> startup ORACLE 例程已经启动。 Total System Global Area 612368384 bytes Fixed Size 1250428 bytes Variable Size 171969412 bytes Database Buffers 432013312 bytes Redo Buffers 7135232 bytes 数据库装载完毕。 ORA-01092: ORACLE 实例终止。强制断开连接 . 赶紧检查alert.log日志：D:\oracle\product\10.2.0\admin\Oracle_SID\bdump\alert.log 发现如下提示： Wed Mar 25 16:59:37 2009 Errors in file d:\oracle\product\10.2.0\admin\katrina\udump\katrina_ora_3284.trc: ORA-00704: 引导程序进程失败 ORA-39700: 必须用 UPGRADE 选项打开数据库 Wed Mar 25 16:59:37 2009 Error 704 happened during db open, shutting down database USER: terminating instance due to error 704 Wed Mar 25 16:59:38 2009 Errors in file d:\oracle\product\10.2.0\admin\katrina\bdump\katrina_pmon_3176.trc: ORA-00704: bootstrap process failure . 说明在升级过程中，只安装了补丁软件，没升级数据字典，因而造成数据库打不开，报ORA-00704:bootstrap process failure错误，按照正常升级数据字典的步骤进行即可。 SQL>startup upgrade SQL>@D:\oracle\product\10.2.0\db_1\rdbms\admin\catupgrd.sql SQL>@D:\oracle\product\10.2.0\db_1\rdbms\admin\catalog.sql SQL>shutdown immediate SQL>startup 数据库启动成功。 SQL> startup upgrade 如果是RAC,先创建pfile,修改增加 SQL> create pfile='/u01/app/oracle/pp.ora' from spfile; File created.
