Displays the selected indexes in a table.
Type a data set name in Temporary work data set field, or for version 7, open a window where you can specify a template to dynamically allocate the data sets. DB2 uses the information that you type in this field to identify the temporary work files used during REBUILD INDEX. SYSUT1 is the data definition (DD) name associated with this data set name.
Specify a direct-access storage device type in which you are authorized to allocate space. Assign frequently accessed objects to fast devices and seldom-used objects to slower devices. You can also specify a tape device.
Allocate space compatible for your device. If your device is DASD the space allocation is in cylinders. If your device type is tape, you can leave this blank.
Optional: Specify a device type for temporary data sets to be dynamically allocated by DFSORT. It can be any device type acceptable to the DYNALLOC parameter of the SORT or OPTION control statement for DFSORT. For example, if you do not specify a device type in this field and a sort is required, you must provide the data definition (DD) statements that the sort program requires for the temporary data sets.
Type a number between 1 and 255. Tip: To optimize resource allocation, avoid specifying a large number of work data sets unnecessarily.
Select the Number of DFSORT temporary data sets check box if you want to specify the maximum number of data sets. If you select the check box, type a number in the associated text field. If you do not select this check box, DFSORT uses a default maximum number of data sets.
Select sort the keys in parallel unless constrained by storage or memory limitations. Sorting the keys in parallel will improve performance. The greatest improvement in elapsed time occur when parallel sorting is applied to:
Select to specify that DB2 can use non-empty data sets during the REBUILD. If you have not defined VSAM data sets with the REUSE option or do not specify this option the data sets used during REBUILD must be empty.
Specifies that the DB2 catalog will be updated (unless you specify Do not update catalog).
Specifies that the statistics in the DB2 catalog will not be updated. Unavailable if you select Do not update catalog.
Specifies that the utility updates all the statistics.
Specifies that the utility updates only the catalog tables used for access path selection.
Specifies that the utility updates only the catalog that provide statistics to help database administrators assess the status of a space or index.
Select to specify to collect all of the distinct values in all of the 1 to n key column combinations for the specified indexes, where n is the number of columns in the index.
Adds a row to the Frequent values statistics options list.
Removes the selected row from the Frequent values statistics options list.
Submits the data in the window and closes the window.
Displays the SQL statements that would be generated by your choices in this window.
Cancels any unsaved changes and closes the notebook or window.
