An interface to profile existing PL/SQL applications and identify performance bottlenecks - collecting and persistently storing granular execution data at the virtual machine level. Overview DBMS_PROFILER provides an interface to profile existing PL/SQL applications and identify performance bottlenecks. It lets us collect and persistently store profiler data. The profiler gathers information at the PL/SQL virtual machine level , including the total number of times each line has been executed, the total time spent on that line, and the minimum and maximum execution times for each line.

Dynamic Column Labels in Oracle APEX Interactive Grid Using Page Items Oracle APEX / JavaScript  ·  Interactive Grid When building data-driven applications in Oracle APEX, column headers sometimes need to reflect dynamic labels rather than hardcoded ones. This post walks through generating column names from a page item value. The Requirement The goal was straightforward: an Interactive Grid whose column headers are generated dynamically based on a page item, updating both on page load and whenever the user changes the item value manually. The page item P24_LABEL_ITEM holds a range string in this format: RESULT1-RESULT5 This means the grid columns should be labeled RESULT1,RESULT2, RESULT3 ... RESULT5 sequentially — without any hardcoding in the region or column settings. The JavaScript Solution Place the following code under Execute when Page Loads . The same block can be reused inside a Dynamic Action triggered on...
