How does Oracle see where the stored procedure is executed?

Methods to track the execution location of Oracle stored procedures include: Use the DBMS_APPLICATION_INFO.ACTION function in the DBMS_APPLICATION_INFO package to view it directly. Enable the PL/SQL debugger and set breakpoints to step through the stored procedure to see where it is executed. Enable SQL Trace or view the execution plan to indirectly obtain stored procedure execution details.

Tracking the execution location of Oracle stored procedures

Direct method: DBMS_APPLICATION_INFO package

Question: How to directly view the current execution location of the stored procedure?

Answer: Use the DBMS_APPLICATION_INFO.ACTION function in the DBMS_APPLICATION_INFO package.

Detailed description:

DBMS_APPLICATION_INFO package provides a function that describes the execution status of the current session. To view the current execution position of a stored procedure, use the following steps:

• In SQL*Plus or SQL Developer, execute the following statement:

  <code class="sql">SELECT DBMS_APPLICATION_INFO.ACTION
  FROM DUAL;</code>

• The result will display the current execution stage of the stored procedure, for example:

  • CALL: The stored procedure is being called.
  • BODY: The body of the stored procedure is being executed.
  • RETURNS: The results of the stored procedure are being returned.

Indirect Method: PL/SQL Debugger

Question:How to use the PL/SQL Debugger Step through a stored procedure and see where it is executed?

Answer: Enable the PL/SQL debugger and set breakpoints.

Detailed instructions:

• In SQL*Plus or SQL Developer, use the ALTER SESSION SET SQL_TRACE = TRUE statement to enable PL/ SQL debugger.
• Open the source code of the stored procedure and set breakpoints.
• Execute stored procedures and use the debugger to step through the code.

Other methods:

• SQL Trace: By enabling SQL Trace, you can log View detailed information about the execution of the stored procedure in the file, including execution time and steps.
• Execution Plan: Viewing the execution plan of a stored procedure can provide information about the execution path and the current execution stage.
