ERROR at line 1:
ORA-01144: File size (4325376 blocks) exceeds maximum of 4194303 blocks

$oerr ora 1144
01144, 00000, "File size (%s blocks) exceeds maximum of %s blocks"
// *Cause: Specified file size is larger than maximum allowable size value.
// *Action: Specify a smaller size.

在db_block_size=8192时，最大块数是4194303
大概是32GB
SQL> select 34359730176/(1024*1024*1024) from dual;

34359730176/(1024*1024*1024)
----------------------------
31.9999924

所以，如果想让datafile超出32GB,可以设置更大的块 (在建表空间时可以指定)

[@more@]

或者创建bigfile的表空间,下面是一个例子

SQL> set head off
SQL> set linesize 1000
SQL> set pagesize 0
SQL> col tablespace_name for a10
SQL> col file_name for a50
SQL> select ts.tablespace_name,ts.BLOCK_SIZE,ts.status,df.file_name,df.bytes/(1024*1024*1024) bytes,df.BLOCKS,ts.BIGFILE
2 from dba_tablespaces ts,dba_data_files df
3 where df.tablespace_name=ts.tablespace_name;
