During peak times you might want to tune performance by temporarily taking indexes offline. For example, to achieve additional bulk-load speed, you might want to suspend all of the user-defined indexes. Because each object addition or modification requires updating defined indexes, having all indexes active might slow down bulk-loading of data. After the bulk-load is completed, the indexes can be brought online again.
To make an Index offline:
Click the Index Management option from the Identity Console landing page.
Select the NCP server and type of the Index, then click the button.
Click the drop-down list for State from the list of indexes. An index can have the following states:
Online: Currently running
Offline: Suspended. The index can be started again.
NOTE:The state of System and Operational type Indexes can not be changed. Such Indexes cannot be deleted as well.
