Expect script
A script written using
expect
, a scripting language based on Tcl, the Tool
Command Language. Can be written to perform automation and testing
operations that are not possible with other scripting languages. Cyclades uses
expect
scripts in some of its AlterPath products, and users can customize
some of the default expect scripts. For example administrators of the
AlterPath OnBoard can customize the Expect scripts that handle
conversations with service processors and other supported devices.
failover
A high-availability feature that relies on two redundant components in a
system or a network, with the second component available to automatically
take over the work of the primary components if the primary component
becomes unavailable for any reason. When the primary component becomes
available, it takes over the work again. Automatically and transparently
redirects requests from the unavailable component to the backup component.
Used to make systems more fault-tolerant. See
