DB2 Maestro online Help

Sequence Editor

Use Sequence Editor to change properties of existing sequences. The editor can be opened automatically after the sequence is created or from the Explorer Tree and Object Manager.

The basic principles of Object Editors in DB2 Maestro are considered in the corresponding topic. See below to find the description of editor tabs that are unique to the current object.

Name

Here you can rename the sequence.

Owner

Shows the owner of the sequence. By default, only the owner of an object can perform various operations with the object. In order to allow other users to operate it, privileges must be granted. (However, users that have the superuser attribute can always access any object.) Start Value contains the starting sequence value here.

Increment by

Here you can edit the value which is added to the current sequence value to create a new value.

The Maximum Value and the Minimum Value contain the maximum and the minimum values for the sequence.

Cashe size

Specify how many sequence numbers are to be preallocated and stored in memory for faster access.

Order

Specify the option to guarantee that sequence numbers are generated in order of request. This clause is useful if you are using the sequence numbers as timestamps. Guaranteeing order is usually not important for sequences used to generate primary keys.

Cycle

The checkbox represents whether the sequence is cycle.

To apply the changes, select the Apply Changes item in the Navigation bar or use Ctrl+F9 or Ctrl+F7 shortcut keys.

It is also possible to modify object properties without opening the object editor: use the Object Properties item of the popup menu of the selected object from the explorer tree.
