| 6 | Feature: Distributed Locking |
| 7 | **************************** |
| 8 | |
| 9 | Summary |
| 10 | ^^^^^^^ |
| 11 | |
| 12 | The Distributed Locking Feature provides locking of resources across a pool of PDP-D hosts. The list of locks is maintained in a database, where each record includes a resource identifier, an owner identifier, and an expiration time. Typically, a drools application will unlock the resource when it's operation completes. However, if it fails to do so, then the resource will be automatically released when the lock expires, thus preventing a resource from becoming permanently locked. |
