Reports the number of transactions rolled back.
Use this to calculate the transaction rollback ratio, which is the ratio of transactions that have rolled back to the number of total transactions involving the EJB:
Transaction Rollback Ratio = (Transaction
Total Rollback Count / Transaction Total
Count) * 100
This information is useful for several reasons. First, it may be useful for signaling a problem with an application. For example, an unexpectedly high rollback ratio may be caused by a problem with a resource used by the application.
You can also use it to gauge the efficiency of an application. A high transaction rollback ratio may mean that a lot of work is being done only to eventually be rolled back, which is inefficient.
