Editing Tablespace General

Tablespace Type

PERMANENT
A permanent tablespace contains persistent schema objects. Objects in permanent tablespaces are stored in datafiles.

TEMPORARY
A temporary tablespace contains schema objects only for the duration of a session. Objects in temporary tablespaces are stored in tempfiles.

UNDO
An undo tablespace is a type of permanent tablespace used by Oracle Database to manage undo data if you are running your database in automatic undo management mode.

Data File

Use the Name and Size edit box to set the datafile / tempfile name and size.

The Unit drop-down list defines the unit of the size of the datafile / tempfile. Specify the maximum disk space allowed for automatic extension of the datafile. Use the dropdown list K, M, G, T, P or E to specify the size in kilobytes, megabytes, gigabytes, terabytes, petabytes, or exabytes. If you do not specify any of the abbreviations, then the size is interpreted as bytes.

Reuse
To allow Oracle to reuse an existing file.

Path
Specify the path of the datafile / tempfile.

Auto Extend
To ON (enable) or OFF (disable) the automatic extension of a new or existing datafile or tempfile.

Next Size
Specify the size in bytes of the next increment of disk space to be allocated automatically when more extents are required. The default is the size of one data block. Use the dropdown list K, M, G, T, P or E to specify the size in kilobytes, megabytes, gigabytes, terabytes, petabytes, or exabytes. If you do not specify any of the abbreviations, then the size is interpreted as bytes.

Unlimited Max
Unlimited disk space that Oracle can allocate to the datafile or tempfile.

Max Size
Specify the maximum disk space allowed for automatic extension of the datafile. Use the dropdown list K, M, G, T, P or E to specify the size in kilobytes, megabytes, gigabytes, terabytes, petabytes, or exabytes. If you do not specify any of the abbreviations, then the size is interpreted as bytes.
