Running the Top N EJB or Top N EJB Methods Report
Summary: Run a report to identify which EJBs run slowest and are used most often
on your WebLogic servers, then run another report to find which specific
methods in those EJBs are slowest and most frequently called.
You can use this information to decide which EJBs and which EJB
methods should be watched more closely. You may also be able to tweak
problematic EJBs to optimize performance.
To run the Top N EJB report:
Step 1
Right-click the server instance icon.
Step 2 From the KM Commands, choose Advance Monitoring => Report Top N
EJB
.
The Report on Top N EJB Data Collection dialog is displayed.
Step 3 Select the checkbox for the criterion you want used to determine “top”
SQL, then slide the control to indicate the number of results you want.
Step 4 Click OK.
