The Application Profiling wizard in Sybase Central provides you with a simple, automated method of performing a diagnostic tracing session for the purpose of profiling applications. The wizard gathers valuable data on how your applications are interacting with the database, and then it provides you access to the data it gathered, as well as indexing recommendations, if any.
When you use the Application Profiling wizard in Sybase Central, the wizard automatically creates a tracing database with the same name you specify in the wizard for the analysis file. For more information on the database files created for application profiling and diagnostic tracing, see Tracing session data.
The Application Profiling wizard cannot be used to create a tracing session for a database running on Windows CE. You must use the Database Tracing wizard. See Creating a tracing session.
Connect to the database as the DBA.
Choose Mode > Application Profiling.
If the Application Profiling wizard appears, follow the wizard instructions.
If the wizard does not appear, choose Application Profiling > Open Application Profiling wizard, and then follow the wizard instructions.
The wizard creates a local database to hold diagnostic tracing information, starts the network server, starts a tracing session, and then prompts you to run the application you would like to profile. Do not click Finish; this ends profiling, and closes the wizard.
Run the application you want to profile. Or, if you are profiling general database usage, allow some time for gathering data. When you have finished, return to the Application Profiling wizard and click Finish. When the wizard finishes, it returns its findings and allows you to review the data it gathered during the tracing session.
For more information on the indexing recommendations returned from the Application Profiling wizard, see Understanding Index Consultant recommendations.
For more information on the procedure profiling information gathered during the tracing session, see How to read procedure profiling results.
