Use this form to define the tablespace or segment that tables and indexes are stored in. The contents of the form vary depending on where the form is called from.

Note Note

Changes to storage options will not take effect before a table or index is re-created. Changes to some storage parameters require that Microsoft Dynamics AX move or rebuild the selected segment. This can be a time-consuming process.

Oracle options

Fields

Field

Description

Available tablespaces are displayed here. The default tablespace for tables is AXTAB. The default tablespace for indexes is AXIDX. Changing this parameter results in a move and rebuild of the segment.

For a detailed explanation of storage settings, refer to Oracle documentation.

Size in kilobytes (KB) of the initial extent in the tablespace. Changing this parameter results in a move and rebuild of the segment.

Size in KB of the remaining extents in the tablespace.

Total number of extents to be pre-allocated for an object.

Total number of extents that can be allocated for an object.

The percentage by which each incremental extent is larger than the last extent for the object.

Reserves a pre-allocated amount of space for simultaneous update transactions. This option is only applicable for tables.

Specifies the maximum amount of simultaneous update transactions at any time. This option is only applicable for tables.

Specifies the percentage of free space allocated in each data block for data or index records to expand when updated. A small percentage value is suitable for tables that are rarely updated.

Displays the percentage of space that is used.

When the amount of data in the data block exceeds this percentage, data is moved to a new data block. This frees the data block for new records. A small percentage value is suitable for tables that are rarely changed.

Displays the number of free lists for the segment.

Displays the number of free list groups for the segment.

Changing this parameter results in a move and rebuild of the segment.

Oracle options

The following table lists the options that are available when the form is called from a Microsoft Dynamics AX system that is running on Oracle.

The options apply to partitions, tables, and indexes. When partitioning is enabled, only the values specified for partitioning are used.

The storage parameters displayed depend on the settings for the specified tablespace.

Microsoft Dynamics AX uses the following algorithm to determine which type of tablespace to use.

  1. Tablespace specified in the form.

  2. Default tablespace for the segment type (only if one item is selected).

  3. Default tablespace for the current Oracle user.

The storage parameters that are available depend on whether the tablespace is managed locally, and if managed locally, whether the segment space management is manual or automatic.
