BladeManager Database Transaction Support

The BladeManager commits all successful database transactions to the BladeManager database. To ensure data integrity, the BladeManager roll will roll back any failed database transaction in the event that:

•There are concurrent users updating the same record at the same time or

•A system fault caused the database transaction to fail.

When multiple users who are logged in as admin update the same record simultaneously, the system will generate a warning message to one of the users:

>> Responding to the Warning Message

When you receive the above warning message, you must perform the following steps:

1.Click on the Reload button located at the bottom of the screen. The system displays the screen that you were updating.

2.Verify the information to determine if you still need to update the form. If you need to update the form, then proceed to re-update the form and then click on Save.

Optimistic locking is a mechanism to lock objects in multi-user systems to preserve integrity of changes so that one person’s changes do not accidently get overwritten by another. It offers reduced concurrency, higher performance, and avoids deadlocks.
