cd $ORACLE_BASE/oradata/orcl -rw-r----- 1 oracle oinstall 104865792 Jan 27 17:43 undotbs01.dbf启动数据库都mount状态
SQL> startup mount pfile='/DBBK/oracle/product/11.2.0.1.0/dbs/initorcl.ora'; ORACLE instance started. Total System Global Area 6680915968 bytes Fixed Size 2213936 bytes Variable Size 3758098384 bytes Database Buffers 2885681152 bytes Redo Buffers 34922496 bytes Database mounted.查看启动参数,发现数据库mount的是UNDOTBS2
SQL> show parameter undo_tablespace NAME TYPE VALUE ------------------------------------ --------------------------------- ------------------------------ undo_tablespace string UNDOTBS2 SQL> show parameter pfile NAME TYPE VALUE ------------------------------------ --------------------------------- ------------------------------ spfile string那么这里可以确定,因为我启动的时候没有使用SPFILE,或者另一种情况SPFILE中的参数值被我不小心改错了。导致启动时候加载错误而参数的报错。
