Altering an index
Use the Alter Index window to modify some properties of an index.
Authorities and privileges
To alter an index:
-
Open the Alter Index window.
- The information on the Index page is read-only,
except for the index type radio buttons.
The Index page describes the index that is
currently being altered. You cannot alter
the index name, index owner, or other properties
listed on this page.
You can use the Index type radio buttons to convert the index from
a type 1 to a type 2. Use type 2 indexes
whenever possible. Type 2 indexes provide
functions that are unavailable with type
1 indexes, such as:
- Row locking on the table space
- UR isolation for an access path
- Processing of queries by multiple parallel
tasks
- Concurrent access to separate logical partitions
-
Specify new values for the optional properties in the
Properties page.
-
If you are altering a non-partitioned index, specify
new values for storage allocation properties in the Index Space Management
page.
- If you are altering a partitioned index,
change partition management properties in
the Partition Management page. The Data management at partition level displays the defined partition management
settings. To change the properties of a partition,
click the Change push button.
-
Click OK to alter the index.
