How many data files can be associated with a single tablespace?

Can there be more than one data file per tablespace?

Yes, there can be more than one datafile per tablespace. When a schema object such as a table or index is created, its segment is created within a designated tablespace in the database. For example, suppose you create a table in a specific tablespace using the CREATE TABLE command with the TABLESPACE option.

How many tablespaces can a data file associate to?

A datafile can be associated with only one tablespace and only one database. Oracle creates a datafile for a tablespace by allocating the specified amount of disk space plus the overhead required for the file header.

How many datafiles are in the Oracle database?

A database's data is collectively stored in the datafiles that constitute each tablespace of the database. For example, the simplest Oracle database would have one tablespace and one datafile. A more complicated database might have three tablespaces, each comprised of two datafiles (for a total of six datafiles).

What is max size in tablespace?

A bigfile tablespace contains only one datafile or tempfile, which can contain up to approximately 4 billion (232) blocks. The maximum size of the single datafile or tempfile is 128 terabytes (TB) for a tablespace with 32K blocks and 32TB for a tablespace with 8K blocks.
