今天把Oracle数据库 10.2.0.1升级到10.2.0.5
然后启动数据库的时候出错：
ORA-01092: ORACLE instance terminated. Disconnection forced 实例终止并强制断开。
遂查看数据库警报日志， 默认地址 $ORACLE_BASE/admin/$ORACLE_SID/bdump/ 目录下的aler_SID.log
[oracle@RedHat4 bdump]$ cd $ORACLE_BASE/admin/$ORACLE_SID/bdump/
[oracle@redhat4 bdump]$ pwd
/u01/app/oracle/admin/crab/bdump
[oracle@redhat4 bdump]$ vim alert_crab.log

找到问题关键
oracle 10g官方文档显示 ：
Cause: A normal database open was attempted, but the database has not been upgraded to the current server version.
Action: Use the UPGRADE option when opening the database to run catupgrd.sql (for database upgrade), or to run catalog.sql and catproc.sql (after initial database creation)
我只安装了升级包，没有执行升级数据库的过程
进入数据库，启动到upgrade
sqlplus / as sysdba
startup upgrade
@/u01/app/oracle/product/10.2.0/db_1/rdbms/admin/catalog.sql
@/u01/app/oracle/product/10.2.0/db_1/rdbms/admin/catproc.sql
这俩个脚本比较慢 我执行了半小时
或者亦可以 @/u01/app/oracle/product/10.2.0/db_1/rdbms/admin/ catupgrd.sql
然后关闭数据库，再启动
SQL> select open_mode from v$database;
OPEN_MODE
----------
READ WRITE
1 row selected.
SQL> show user
USER is "SYS"
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup
ORACLE instance started.
