标签归档:update props$
修改props$.NLS_CHARACTERSET导致ORA-00900异常恢复
今天一朋友和我说他的数据库不能open,open过程提示ORA-00900错误,通过分析alert日志和props$表,发现他们修改了一个无效的NLS_CHARACTERSET值,导致数据库无法正常启动(准确的说,因为数据库里面该值无效,当数据库open的过程中,检测到控制文件指定的编码和该值不一致,然后修改控制文件的编码,修改之后,数据库一到mount状态执行任何语句都报ORA-00900错误),通过一些工具修改NLS_CHARACTERSET为正确值该故障解决
重现ORA-00900故障

第一次startup(open)过程报错

这里比较明显的看到有一条(Updating character set in controlfile to AL16UTF16),正是由于这个操作,更新控制文件的编码为一个无效的编码,从而导致在后面数据库mount(加载控制文件)之后,就不能再进行其他任何操作
解决思路
使用odu找出来block位置,或者在同版本库中查询
使用dul或者bbed修改props$的NLS_CHARACTERSET值
重建控制文件(noresetlogs方式)
处理过程

从oracle 9i开始,修改数据库的编码,直接使用alter database character set internal_use方式进行,而不要使用直接修改props$基表,更不能修改一个实际中不存在的编码值(本文中数据库编码和国家编码搞混淆从而出现该故障)
