How to Check Audit Enabled in Oracle 12c

Oracle 12c, a widely used database software system, offers a feature known as audit logging. It tracks and monitors activities in Oracle databases, preserving data integrity and meeting regulations. Let’s discover how to enable audit logging in Oracle 12c and its importance for a secure database environment.

Data breaches and unauthorized access are realities in the digital world. Oracle 12c’s audit logging is a great security measure. It tracks user actions such as logins, privilege escalations, data modifications, and access attempts. This helps identify suspicious activity and potential vulnerabilities.

To determine if audit logging is enabled in Oracle 12c, administrators can use the AUDIT_TRAIL parameter in the Oracle Database initialization file (init.ora or spfile). The parameter has various values to indicate whether logging is enabled or disabled. These include ‘DB’, ‘OS’, and ‘NONE’.

By checking the value of AUDIT_TRAIL, administrators can be certain that audit logging is capturing relevant user activity information. It’s essential to review these settings regularly to guarantee continuous monitoring and accountability.

It’s worth noting that audit logging can slow down system resources due to increased I/O operations from writing log files. However, the advantages of added security outweigh any potential performance issues.

Oracle Corporation’s documentation states that proper audit configuration is essential for shielding sensitive data and meeting regulatory requirements.

Understanding Oracle 12c Auditing

Oracle 12c Auditing is a must for safekeeping and upholding the integrity of an Oracle database. Here, uncover the basics of Oracle 12c Auditing and how it can be used to trace and monitor database activities.

Auditing allows administrators to document and investigate user activities within the database environment. Enabling auditing can detect potential security breaches, find attempts of unauthorized access, and discover suspicious actions. It furnishes valuable info to comply with regulations like Sarbanes-Oxley (SOX) and the General Data Protection Regulation (GDPR).

To activate auditing in Oracle 12c, one needs to configure the suitable initialization parameters. The audit_trail parameter determines where the audit trail records are kept, while the audit_sys_operations parameter decides if system-level operations should be audited. By changing these parameters to preferred values, one can customize the auditing setup based on special needs.

Once auditing is switched on, it captures various types of auditable events including logins/logouts, privilege usage, data manipulation language (DML) statements such as INSERT/UPDATE/DELETE, and data definition language (DDL) statements e.g. CREATE/DROP/ALTER. This full coverage makes sure that all important actions within the database are properly audited for further review.

Pro Tip: Examining audit logs is indispensable for successful auditing. Examining these logs can reveal patterns or anomalies that may suggest security threats or non-compliance issues. So, it is recommended to develop a systematized way to inspect audit logs occasionally.

Steps to Check if Audit is Enabled in Oracle 12c

Curious how to check if audit is enabled in Oracle 12c? We’ve got you covered! Here’s a quick guide:

  1. Connect to the Oracle Database using SQL*Plus: Open your command prompt or terminal and enter: sqlplus / as sysdba
  2. Check if Audit is enabled: Once connected, run this query: SELECT value FROM v$parameter WHERE name='audit_trail'; If the value returned is DB or TRUE, audit is enabled.
  3. Find audit trail location (optional): To discover where the audit records are stored, execute: SELECT value FROM v$parameter WHERE name='audit_file_dest'; This will indicate the directory path where audit files are saved.
  4. Exit SQL*Plus: After obtaining the info, type exit to end your SQL*Plus session.

By following these steps, you can easily check if audit is enabled in Oracle 12c and even find out where the audit records are stored.

Auditing provides valuable insights into your database activity and ensures compliance with security regulations. It’s important to stay vigilant!

Fun fact: Oracle Corporation acquired Sun Microsystems back in 2010, a significant move that strengthened Oracle’s position in hardware and software technology innovation.

Interpreting the Audit Results

Analyzing audit results involves looking for patterns or anomalies in the data. For example, many failed logins from the same IP could point to a brute-force attack. A sudden surge in privilege escalations might mean an insider threat.

It’s also important to understand the context of each event. Cross-referencing with user roles and permissions helps figure out if an action was legitimate or not.

Prioritize high-risk events. Assign severity levels or focus on activities involving sensitive data or privileged accounts. Quickly address critical issues to reduce damage and improve security.


To check if Oracle 12c has auditing enabled, users can query the V$OPTION view. If AUDIT_TRAIL is set to DB or DB_EXTENDED, auditing is enabled. If it’s set to NONE, auditing is not turned on.

Users should also check if AUDIT_SYS_OPERATIONS is set to TRUE.

Remember, enabling auditing can affect database performance. It’s best for users to test it out and not use it in production straight away.

Additionally, users should monitor the AUD$ table which stores audit trails. This helps detect any security breaches or unauthorized activities.

Pro Tip: Regularly look at audit trails to spot patterns and anomalies. It’s a great way to keep an eye on system activity and potential security risks.

Frequently Asked Questions

FAQ: How can I check if audit is enabled in Oracle 12c?

Answer: To check if audit is enabled in Oracle 12c, you can run the following SQL query: SELECT value FROM V$OPTION WHERE PARAMETER = ‘Unified Auditing’; If the output is ‘TRUE’, then audit is enabled.

FAQ: Are there any other ways to check if audit is enabled in Oracle 12c?

Answer: Yes, besides running the SQL query mentioned earlier, you can also check the audit trail destination by running the command: SHOW PARAMETER AUDIT_FILE_DEST; If the output shows a valid directory path, then audit is enabled.

FAQ: Is there a way to enable audit in Oracle 12c if it is currently disabled?

Answer: Yes, audit can be enabled in Oracle 12c by executing the following SQL statement: ALTER SYSTEM SET audit_trail = db, extended scope = spfile; This will enable database-level auditing with extended auditing options.

FAQ: How can I verify if the audit configuration change was successful?

Answer: After enabling audit in Oracle 12c, you can verify the configuration change by running the query: SELECT value FROM V$OPTION WHERE PARAMETER = ‘Unified Auditing’; If the output is ‘TRUE’, then the configuration change was successful.

FAQ: Can I enable audit in Oracle 12c without restarting the database?

Answer: Yes, you can enable audit without restarting the database by using the following command: ALTER SYSTEM SET audit_trail = db, extended; This will enable database-level auditing without the need for a restart.

FAQ: Is there any specific software required to check audit enabled in Oracle 12c?

Answer: No, there is no additional software required to check if audit is enabled in Oracle 12c. It can be done using SQL queries and commands directly within the Oracle database.
