官方解释

常见案例

一般处理方法及步骤

1、查看块大小是否已经更新：用 SELECT BLOCKSIZE FROM DBA_DATA_FILES;

2、若不存在，则需要重建表空间，存储更新后的块大小：DROP TABLESPACE 某表空间名;

CREATE TABLESPACE 某表空间名 DATAFILE ‘路径及文件名’ SIZE 尺寸

BLOCKSIZE 块大小 EXTENT MANAGEMENT LOCAL AUTOALLOCATE SEGMENT SPACE MANAGEMENT

AUTO;

3、当表空间重建完成后，查看一下：SELECT BLOCKSIZE FROM DBA_DATA_FILES;

希望上述步骤能够帮助用户解决更改表空间块大小失败的问题。
