Global Lock Conflicts workspace

The Global Lock Conflicts workspace provides a global view of lock conflicts for an entire data sharing group. Use the Global Lock Conflicts workspace to:

This workspace contains a:

Monitoring database lock activity

You can sort and filter information in the workspaces to change the way you see information. For example, you may want to monitor critical transactions with a lock elapsed time of greater than 10 seconds. Notice that, by default, the view shows lock elapsed time in descending order. This makes it easy to identify the transactions with a lock elapsed time of greater than 10 seconds.

Investigating a true database lock situation

You can use this workspace to investigate a database lock situation, viewing locking data for one or more transactions that caused a situation to evaluate to true. You may want to investigate the predefined situation, IMS Lock Waiter Time Critical, which evaluates to true when the lock elapsed time is greater than 10 seconds and lock status is Waiter. Filter the view to show only those transactions with a lock elapsed time greater than 10 seconds. On the filtered view, identify all transactions with a Waiter lock status.

Identifying long locks

The Global Lock Conflicts workspace for lock conflicts provides the following links:

The workspace provides a link to another workspace that shows owners and waiters for a specific lock. This can be used in environments that have a significant number of lock conflicts where it becomes difficult to associate owners and waiters for the lock. An additional field for lock owner type records provides the count of tasks waiting on the lock.

Navigating intelligent cross-product workspace links

To improve integration among the applications and monitoring agents that use the Tivoli Enterprise Portal to display data, a new dynamic linking between workspaces is now available and is known as dynamic workspace linking.

Note:
Dynamic workspace linking is supported only between V4.1.0 (and higher) workspaces. Predefined cross-product links to other product workspaces are not displayed if the other product has not been installed and configured.
