Unlock resource Version 4 (Java)

Action group: Orchestrator Subgroup: Resource queues

Description

The action unblocks a queue item that was previously blocked by the same robot.

  1. The action sends a request to unblock a resource created in the resource queue in the Orchestrator database. The resource is searched by the specified resource identifier

  2. You can only remove a lock if the robot instance is the owner of the lock. The owner of the lock is the user or robot instance that set the lock. And different locks can have different owners. Two different launches of the same robot (2 different instances) have different owners.

  3. Users have more authority than robots, so they can remove/set locks regardless of who owns them.
  4. If the action should release a read lock, but the resource is not locked for reading, the action will not return an error, just skip working with that lock. The same is true for removing a write lock.
