Chapter 4 • Working with Quality Center Synchronizer

The Synchronizer can run only one task at a time for a particular synchronization link. The Synchronizer resolves possible conflicts between tasks using the following rules:

➤If a task is already running for a link and the scheduled time for a second task of a different type arrives, the second task waits in a queue and runs immediately upon completion of the first task. If the second task is of the same type, for example if they are both incremental synchronization tasks, the second task does not run at all.

➤If both an incremental synchronization task and a full synchronization task for the same link are scheduled for the same time, the full synchronization task runs before the incremental synchronization task. The incremental synchronization task enters a queue and runs upon completion of the full synchronization task.

The Synchronizer can run one full synchronization task or five incremental synchronization tasks from different links simultaneously. If the scheduled time for an additional task arrives when the maximum number of tasks is already running, the additional task waits in a queue. When a task that is currently running completes, the additional task runs.

To run a link task in automatic mode:

1Ensure that the link has passed an integrity check. For information on integrity checks, see “Integrity Checks” on page 37. For information on running an integrity check, see “Running Link Tasks Manually” on page 91.

2Ensure that the task is set to run in automatic mode in the Scheduling tab. For more information on editing configuration settings for a link, see “Editing Synchronization Link Settings” on page 99. For more information on available settings for running tasks automatically, see “Setting Scheduling Options” on page 54.

3Ensure that the link is enabled. For more information on enabling links, see “Enabling and Disabling Synchronization Links” on page 102.

4If a task is currently running for a link, a green arrow is added to the link’s icon in the Links list. To verify that the information displayed is current, click the Refresh Selected button or click the down arrow and select Refresh

Selected.
