How to Check Hidden Parameters in Oracle 11g: A Step-by-Step Guide

In this guide, we’ll go over how to check hidden parameters in Oracle 11g and explain why it’s important to do so regularly.

When you set up a database on your own, it can be easy to overlook some of the more obscure settings. But these hidden parameters can have a big impact on your database performance, security, and scalability.

To check these parameters, follow these steps:

  1. Open SQL Plus or any other tool that allows you to access the Oracle database management system (DBMS).
  2. Connect to the database using your username and password.
  3. Type "SHOW VARIABLE_NAME ‘parameter_name’"; replace "variable_name" with the name of the parameter you want to check, and "parameter_name" with the actual parameter value.
  4. Repeat this process for all the parameters you want to check.

It’s also a good idea to run regular queries to monitor your database performance, such as querying the SGA (System Global Area) or checking the AWR (Automatic Memory Management) reports.

By regularly checking hidden parameters and monitoring your database performance, you can ensure that your database is running optimally and securely. This will help you avoid any costly downtime or security breaches, and ultimately lead to better overall database performance.
