Before working with tablespaces of an Oracle Database, familiarize yourself with the guidelines provided in the following sections:
Using Multiple Tablespaces
Using multiple tablespaces allows you more flexibility in performing database operations. When a database has multiple tablespaces, you can:
Some operating systems set a limit on the number of files that can be open simultaneously. Such limits can affect the number of tablespaces that can be simultaneously online. To avoid exceeding your operating system limit, plan your tablespaces efficiently. Create only enough tablespaces to fill your needs, and create these tablespaces with as few files as possible. If you need to increase the size of a tablespace, add one or two large datafiles, or create datafiles with autoextension enabled, rather than creating many small datafiles.
Review your data in light of these factors and decide how many tablespaces you need for your database design.
Assigning Tablespace Quotas to Users
Grant to users who will be creating tables, clusters, materialized views, indexes, and other objects the privilege to create the object and a quota (space allowance or limit) in the tablespace intended to hold the object segment.
