Presentation Synopsis<br />
The scope of this presentation includes:<br />
• Outline the most optimum process to avoid order dead lock<br />
• Share resolution steps in case order deadlock occurs<br />
• Explain the correct process to swap the circuits between the two portaddresses<br />
/equipments<br />
Our goal is to help MetaSolv business users to reduce the order<br />
completion time during order dead lock issue without software fix<br />
and resolve the issue.<br />
<strong>Order</strong> dead lock is one of the most<br />
commonly occurring issues for<br />
MetaSolv business users while<br />
grooming the facilities. This issue<br />
appears on all MetaSolv order types.<br />

What is an <strong>Order</strong> <strong>Dead</strong> <strong>Lock</strong>?<br />
A situation in MetaSolv where two orders and two circuits sharing<br />
the same equipment/circuit properties prevent each order from<br />
completing Due Date task<br />
This issue generally happens while grooming circuits between the<br />
port addresses<br />

Summary of circuit and port status<br />
To summarize we have the following situation<br />
Port JK 1 – (Pending Disconnect) 101/T1 (C1 Change <strong>Order</strong>)<br />
(Pending) 102/T1 (C2 Change <strong>Order</strong>)<br />
Port JK 4 – (Pending Disconnect) 102/T1 (C2 Change <strong>Order</strong>)<br />
(Pending) 101/T1 (C1 Change <strong>Order</strong>)<br />
Pending Disconnect <strong>Order</strong> needs to be finished before a Pending <strong>Order</strong><br />
According to the Status of Port JK1, C1 needs to be completed before C2<br />
According to the status of Port JK2, C2 needs to be completed before C1<br />
This leads to a deadlock situation where none of the orders could be<br />
completed<br />

<strong>Dead</strong> <strong>Lock</strong> <strong>Order</strong> – Resolution Steps<br />
Here is the task completion window for change order #1<br />
Enter a new Change <strong>Order</strong> C3 to assign 101/T1 to (Port JK 4) where 102/T1 was<br />
disconnected. Assign tasks, work the circuit, DLRD/RID Issue the circuit, and then<br />
complete the tasks to put 101/T1 in service. Similarly create another change order for<br />
102/T1 and make it In-service.<br />
