Lock Accumulator

This Accumulator step locks an instance of an accumulator so that the value does not change. This step prevents another accumulator tool from changing a value before that value can be retrieved. A lock will eventually expire so that other tools can get or change the value of an accumulator instance.

Inputs

Accumulator Name

The name of the accumulator to lock. This name is defined in Interaction Administrator.

Instance Name

The specific instance of the accumulator you want to lock. The rules for this instance name are defined in Interaction Administrator.

Outputs

Accumulator Key

Contains the value of the key. This key must be used by tools that access this accumulator instance. This key must also be provided to an Unlock Accumulator step.

Exit Paths

Success

This step takes the Success exit path if the operation is successful.

Failure

This step takes the Failure exit path if the Instance Name is invalid for the accumulator not in the list of valid instances. This would never happen if the Instance type was Any, but it is possible for the other instance types. Failure can also occur when communication between the IP process and the Accumulator server timed out due to heavy machine load.
