Lock
Description
The Lock activity guarantees the execution under the protection of a lock and prevents the other instances of workflows from continuing past this Activity until the specified lock is released.
Design Time Configuration
Lock Type
Select one of the following lock types.
| Type | Description |
|---|---|
| UI | Select this lock type if you want other workflows using the UI to be blocked when an instance of this workflow is running. You can use this lock type in case your workflow performs Web Automation or Desktop Automation. |
| Custom | Select this lock type if you want other workflows using the same Key to be blocked when an instance of this workflow is running. You can use this lock type in case you want to access shared resources across workflows and their instances sequentially. |
Key
In the case of Custom lock type selection, you can specify the name of the Key to be used to lock. The Activity will lock the workflows using the same Key.
The Key is mandatory for the Custom lock type. Provide a name that the lock can use. When two workflows share the same Key name, only one workflow will be able to continue at a time. The second workflow will wait until the first workflow releases the lock.
