Removing accelerators

Follow the steps in this topic to remove accelerators from the system configuration. Bear in mind that this action will also remove the tables from an accelerator.

Before you begin

Important: Make sure that you stop an accelerator before you remove it. Otherwise the heartbeat thread, which provides monitoring information, continues to run. This heartbeat thread might be taken over by a new accelerator if you reuse the name of the removed accelerator. In this case, the heartbeat thread will provide false information because it does not pertain to the new accelerator. For more information, see the attention note in Completing the authentication using the Add Accelerator wizard.
