oracle数据库的最大数据容量限制和表空间的最大数据容量限制

参考原文：
What Is The Maximum Tablespace Size And Database Limit For An Oracle Database ? (Doc ID 1372905.1)

适用于：
Oracle Database - Enterprise Edition - Version 10.1.0.2 to 11.2.0.3 [Release 10.1 to 11.2]
Oracle Database - Enterprise Edition - Version 11.2.0.4 to 11.2.0.4 [Release 11.2]
Information in this document applies to any platform.

目标：
在oracle 10g和11g中，如下的最大值是什么？
database
tablespace
datafile

解决方法：

对于small file database

For a small file database, the Oracle database has the following limits :

maximum number of datafiles is : 65533
maximum data blocks per datafile : 2^22 -1 = 4194303
maximum datafile size = db_block_size * maximum number of blocks
maximum db_block_size = 32 K
maximum tablespace size = 1022 * max database file

Resulting values are:
maximum datafile size = 32 * 4194303 = 128 GB
maximum tablespace size = 1022 * 128 GB = 130816 GB
maximum database size = 128 G * 65533 = 8388224 GB

对于big file database

For a big file database, the Oracle database has the following limits :

maximum number of datafiles is : 65533
maximum data blocks per datafile : 2^32 = 4294967296
maximum datafile size = db_block_size * maximum number of blocks
max db_block_size = 32 K
maximum tablespace size = size of big datafile

Resulting values are:
maximum datafile size = 32 * 4294967296 = 128 TB
maximum tablespace size = 128 TB
maximum database size = 128 T * 65533 =8388224 TB

用语句执行下呢！
ALTER DATABASE DATAFILE1 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\DATA1 AUTOEXTEND ON
NEXT 10240M
MAXSIZE UNLIMITED;
看不能修改是什么错嘛！
还有操作系统有最大文件的大小限制吧！特别是FAT32只有2点多G！
 

如果原库存在，先使用下面语句查询一下，根据查询结果设置文件大小。
select t.tablespace_name, round(sum(bytes / (1024 * 1024)), 0) ts_size
from dba_tablespaces t, dba_data_files d
where t.tablespace_name = d.tablespace_name
group by t.tablespace_name;
如果没有则设置成29G+10G，并且将表空间设置成自动增长。
