How does Oracle see where the stored procedure is executed?

View the execution progress of stored procedures in Oracle: enable SQL tracking: ALTER SESSION SET SQL_TRACE=TRUE; execute the stored procedure; check the tracking file (ora<pid>.trc); analyze the execution plan and statistical information to determine efficiency and improve areas.

Steps to check the execution progress of stored procedures in Oracle

Checking the execution progress of stored procedures in Oracle database is very Important because it can help diagnose problems and optimize performance.

Step 1: Enable SQL Tracing

To enable SQL tracing in Oracle, use the following statement:

<code>ALTER SESSION SET SQL_TRACE=TRUE;</code>

Step 2: Execute stored procedure

Execute the stored procedure to be traced.

Step 3: Check the tracking file

After executing the stored procedure, the relevant tracking information will be stored in the tracking file. By default, the trace file is located in the database server's home directory and is named ora<pid>.trc, where <pid> is the process ID of the current session.

Step 4: Open the trace file

Open the trace file using a text editor or similar tool (such as TKPROF).

Step 5: Find the stored procedure execution information

In the trace file, find the information related to the stored procedure execution. This information is usually in a section labeled:

• SQL text: The text of the stored procedure.
• Execution Plan: Execution plan of the stored procedure.
• Statistics: Execution statistics of stored procedures.

Step 6: Analyze the execution plan

The execution plan shows how the stored procedure accesses data. By analyzing an execution plan, you can determine how efficiently a stored procedure executes and potential areas for improvement.

Step 7: Check Statistics

Statistics provide detailed information about stored procedure execution, for example:

• Each statement executed number of times.
• The number of rows processed by the statement.
• The time required for statement execution.

Tips:

• In order to obtain more detailed tracking information, you can use SET SQL_TRACE=TRUE EXTENDED.
• If the trace file is too large, you can use SET SQL_TRACE=TRUE FORCE to limit it to the latest sessions.
• TKPROF is a tool that helps you format and analyze trace files in a readable format.
