ORA-30014: operation only supported in Automatic Undo Management mode
Cause: the operation is only supported in automatic undo mode.
Action: restart instance in Automatic Undo Management mode before retrying operation.
ORA-30014表明只有在自动撤销管理模式下操作Orcale数据库才支持,否则会报此错误。
错误提示ORA-30014表明需要切换到自动撤销管理模式。该错误之所以报出,是因为你现有的操作不支持使用手动撤消管理模式及非自动撤消管理模式。
1.登录sqlplus,按照以下形式输入指令:
connect sys as sysdba;
2.然后,输入以下指令来切换到自动撤消管理模式:
alter system set undo_management=auto scope=spfile;
3.然后输入以下指令,重新启动数据库:
shutdown immediate
startup
4.然后按照正常步骤进行操作即可:
connect sys as sysdba;
alter system set undo_retention=1800 scope=spfile;
alter system set undo_tablespace=undotbs01;
alter system set undo_retention=1800 scope=both;
