The database as the name implies is the collection of data is also a virtual host to build a Web site storage data tool, and Oracle is the management of these data collection software system, it is an object-relational database management system.

A tablespace is a logical mapping of Oracle's related data on a physical database.


A database is logically divided into a number of table spaces, each containing a set of structures that are logically associated. Each database has at least one tablespace (called the system table space).

Each tablespace consists of one or more files on the same disk, which are called data files (datafile). A data file can belong to only one table space.
Maximum data capacity limits and table space maximum data capacity limits for Oracle databases
Reference to the original:
What is the Maximum tablespace Size and database Limit for Oracle Database? (Doc ID 1372905.1)


Available for: 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.

Goal:
In Oracle 10g and 11g, what is the maximum value below.
Database
Tablespace
DataFile

Workaround:
For 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 = K
Maximum tablespace size = 1022 * Max database file

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

For the 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 = K
Maximum tablespace size = size of big datafile

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