View Partition Information

The Partitioning tab of Object Properties is displayed when a partitioned object, partition, or subpartition is selected in the object tree. The fields in this tab change according to which of these objects is selected.


View Size and Statistics

View the Size and Statistics tab in Object Properties to see storage statistics for a selected object. This tab is displayed for objects that are supported for statistics collection. It is not displayed for objects such as LOBs.

Along with the Reorg Need value, the Size and Statistics tab can help you determine whether the object would benefit from being reorganized.

The Source for Statistics

The Statistics tab displays statistics from the Space Manager Repository.

Tablespace Statistics

  • Block Size—This field displays the data block size for an object’s database or tablespace (in databases that allow block sizes to vary by tablespace).

Allocated Space

  • Segment Size—This field displays total space allocated for an object.

Space Manager Statistics

  • Actually Used—This field displays the amount of space used by an object that currently contains data.

Data Dictionary Statistics

  • Row Count—This field displays the number of rows in a table.
  • Chained Rows Count—This field displays the number of chained rows in a table.

View the Extents tab in Object Properties to see a list of the extents allocated to an object.

Extent Statistics

  • File Name—File name of the datafile for an extent.
  • Status—Whether a datafile is available or not.
  • Autoextensible—Whether a datafile is autoextensible.

The maximum number of extents listed is 500.


View Column Definitions

View the Columns tab in Object Properties to see column definitions for a table, index, cluster, clustered table, or IOT. A yellow key symbol identifies columns that are included in a table's PRIMARY KEY.

The Columns tab is not displayed for partitions and subpartitions.

Note: If a table contains a user-defined datatype or XMLType datatype, the Columns tab displays all hidden columns associated with that datatype.
