Type a data set template name in Temporary work data set field, or 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.

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.

Select to have a set of messages reporting the collected statistics sent to the SYSPRINT data set.

(Default) Select to not have messages reporting the collected statistics sent to the SYSPRINT data set.

Specify how you want the REBUILD to update the DB2 catalog.

Specify how you want the REBUILD to update the DB2 catalog history tables

Select 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.

Number of Columns: Indicates the number of key columns to concatenate when collecting frequent values from the specified index. A value of '3' indicates that DB2 collect frequent values on the concatenation of the first three key columns.

Number of frequent values: Indicates the number of frequent values to be collected. A value of '15' indicates that DB2 collect 15 frequent values.
