ORA01092解决一例

       有一个10G的DB,是从8.1.7.4升级上去的.在IMP资料时出现RBS段不足的问题.今天有更大的资料要导入,干脆将Undo设为AUTO.升级成功以来,一直用原来8I的RBS,今天先将原来的名为RBS的tablespace改名为UNDOTBS1,然后修改INIT参数,将UNDO设为auto, undo tablespace name 设为UNDOTBS1,然后重新启动oracle,在startup时,系统报ORA-01092: ORACLE instance terminated. Disconnection forced.查看alter文件,发现ORA-30012: undo tablespace '' does not exist or of wrong type错误.看来是undo tablespace的类型给搞错了,刚才改了名,类型没改变为undo.将 init参数undo=auto取消掉后,再重新启动.修改undotbs tablespace的类型为undo,结果出现错误.干脆删除undotbs1 tablespace, 重新建立undo tablespace undotbs1,修改init文件,加上参数undo=auto,重新启动oracle 后正常.
