  1. IMPROVING PL/SQL PERFORMANCE IN ORACLE APEX It’s very easy to write PL/SQL in Oracle Application Express but it will degrade the performance of the Application because of a compilation of PL/SQL at runtime. Keep the volume of code inside the Oracle Application Express application to a minimum. The simplest tuning technique to improve performance is to encapsulate PL/SQL within packages. This applies to any PL/SQL processes on page, plug-in, dynamic actions, validations, computations and dynamic PL/SQL.This change improves the execution time of PL/SQL as it’s processed at compile time instead of being parsed and compiled at runtime. Plug-ins can be wonderful black boxes and consumers may not care how it works or looks under the hood. You can always improve the performance of a plug-in by shifting the supplied code into a PL/SQL package.

  2. Move the code from the source of the Move the code from the source of the plug-in as a procedure in a package, perhaps in a package, perhaps plugin_util. Then change the “Render function name” Then change the “Render function name” to plugin_util.screen_saver_vik. _util.screen_saver_vik.

  3. Benefits of moving PL/SQL within packages: 1. Faster execution of Apex pages. 2. Less PL/SQL compilation at runtime. 3. Code is more maintainable and reusable. 4. Apex application export files are smaller – faster to deploy.
