表空间不足问题-表空间文件自增

无法通过 128 (在表空间 IRRZJZS 中) 扩展

--查看表空间
SELECT * from dba_tablespaces;

--查看表空间文件路径

select tablespace_name,file_id,file_name from dba_data_files order by 1,2;

--查看用户和默认表空间的关系
SELECT username,default_tablespace from      dba_users;

---------------------

单文件32g 问题注意 --根据系统环境，4k 16g 8k 32g


ALTER DATABASE DATAFILE 'C:\ORANT\ORADATA\xxx\xxx.ORA' AUTOEXTEND ON MAXSIZE UNLIMITED;

alter tablespace tablespace_all.tablespace_name  add datafile  all_file_name  SIZE 1024M AUTOEXTEND ON NEXT 200M MAXSIZE UNLIMITED
