| 45 | * GetStatus ZOO Service : |

---|
| 49 | * will access the shared memory space created by the Kernel to extract the |
---|

---|
| 51 | * finally produce the final ExecuteResponse including the updated |
---|
| 52 | * percentCompleted attribute of the ProcessStarted node of the cached |
---|
| 53 | * document if any (so if the Service is currently running) else it will |
---|
| 54 | * return the final ExecuteResponse stored on the Server file system. |
