Metric Descriptions

Allocated Space Used Pct

The percent of used allocated space within this tablespace

Allocation Type

The type of extent allocation to be used for this tablespace. The possible values for this metric are as follows:

•

•

•

The number of autoextensible ASM datafiles

The number of autoextensible OS datafiles

Average Fragment Size

The average size of fragments in this tablespace

Indicates whether the tablespace is a BIGFILE tablespace. BIGFILE tablespaces are supported only for locally managed tablespaces with automatic segment-space management.

The tablespace blocksize

The type of tablespace contents is one of the following:

•

•

•

The database name

Default Table Compression

Indicates whether table compression is enabled by default for this tablespace

Indicates whether the tablespace data is encrypted.

Estimated Date Until Full

The estimated date when the tablespace becomes full.

Estimated Until Full

The estimated number of days until the tablespace is full.

Extent Management

Indicates the extent management type:

•

DICTIONARY — where the management of extents is within the Oracle data dictionary.

•

LOCAL — where the management of extents is within the tablespace itself.

Indicates whether the tablespace is in FORCE LOGGING mode:

•

Yes — logs all changes to all objects in the tablespace except changes to temporary segments.

•

No — logs are not created.

The number of fragments in this tablespace

The total amount of free space in this tablespace

The percent of free space in this tablespace

Indicates whether a redo log is to be generated for the tablespace

Long Term Growth Rate

The long term growth rate.

The number of manual ASM datafiles

The number of manual operating system datafiles

Max Fragment Size

The size of the largest fragment in this tablespace

Min Fragment Size

The size of the smallest fragment in this tablespace

Number of Datafiles

The number of datafiles in the tablespace

In multitenant architectures, the name of the pluggable database

Recycle Free Pct

The percentage of recycle bin space which occupies the allocated free space of the tablespace.

The total amount of space used by the recycle bin within the allocated free space of the tablespace

Indicates whether unexpired UNDO operations are retained in the tablespace. This applies only to UNDO tablespaces.

Segment Space Management

Indicates the method used for managing free and used segments:

•

manually — by free lists

•

automatically — by bitmaps

Short Term Growth Rate
