今天在上看到“关于9i以后block format的含义”的文章，在本机上进行了测试。测试过程如下：

C:Documents and SettingsAdministrator>sqlplus / as sysdba

SYS@kuqlan10>create table t8k tablespace users as select * from dba_users;

表已创建。

SYS@kuqlan10>alter system checkpoint;

系统已更改。

SYS@kuqlan10>select dbms_rowid.rowid_relative_fno(rowid)||'_'||dbms_rowid.rowid_

block_number(rowid) location from t8k where rownum<2;

通过cmd打开另外一个窗口，具体执行步骤如下：

C:bbed>bbed parfile=par10g.txt

Block format有了直观认识，但是不知后面的BBED-00400: invalid blocktype (35)错误是怎么排除？

bbed亲身体会，查看block format
