Enabling ALT

Constraints

• The TaurusDB instance's kernel version must be 2.0.54.240600 or later, and the proxy instance's kernel version must be 2.24.06.000 or later. For details about how to check the kernel version, see How Can I Check the Version of a TaurusDB Instance?
• When you enable ALT for the first time, the TaurusDB instance will reboot. Enabling or disabling ALT will cause a proxy instance to reboot. Once ALT is disabled for all proxy instances, the TaurusDB instance will also reboot. Rebooting an instance will clear its cache. To prevent traffic congestion during peak hours, you are advised to reboot it during off-peak hours.
