UNDOTBS01.DBF过大
sqlplus / as sysdba登录系统
PDB模式的话先切换Session
alter session set container = ora19cpdb;
确认一下undo的表空间名
show parameter undo;
创建新的undo表空间
create undo tablespace undotbs03 datafile '/opt/oradata/undotbs03.dbf' size 100m autoextend on next 100m;
将undo指向新的表空间
alter system set undo_tablespace=undotbs03;
删除原有表空间
drop tablespace undotbs02 including contents and datafiles;
