Oracle Advanced Compression Licensing and DataPump

Oracle Advanced Compression licensing works as follows:

  • Extra Feature for Oracle Enterprise Edition: Advanced Compression is an additional feature for Oracle Enterprise Edition.
  • Cost: The licensing cost is $11,500 per processor license.
  • License Model Matching: The license model and quantities for Oracle Advanced Compression must match the database license.
  • Non-Transferable Licenses: Oracle licenses are generally non-transferable, but exceptions may apply based on the agreement.
  • Easy Non-Compliance: Using features like Oracle Data Pump without the metadata_only Parameter can trigger Advanced Compression, leading to potential non-compliance.

Oracle Advanced Compression Licensing and Avoiding Compliance Pitfalls

Oracle Advanced Compression Licensing and Avoiding Compliance Pitfalls

Oracle Advanced Compression Licensing often becomes a stumbling block for Oracle database customers, leading them to unintentionally fall out of compliance with their Oracle licenses.

As an Oracle database administrator, you’re likely well-versed in the benefits of data compression.

Oracle Advanced Compression provides a comprehensive suite of data compression and Information Lifecycle Management (ILM) capabilities for all data types, including structured and unstructured data, backup, network, archive, and Data Guard Redo Transport traffic.

Here are some common ways companies can inadvertently become non-compliant with Advanced Compression:

  1. Accidental Activation: Companies can unknowingly activate Advanced Compression. This often happens when using Oracle Data Pump and organizations are not using the metadata_only” parameter, which triggers the Advanced Compression option.
  2. Misunderstanding License Terms: Non-compliance can occur if companies don’t fully grasp their Oracle license terms. It’s crucial to understand precisely what Oracle options your license covers.
  3. Usage of Table Compression: Table compression is another area known to cause non-compliance issues. Companies must ensure they have the appropriate licensing if using this feature.
  4. Lack of Team Awareness: If team members working with Oracle Data Pump aren’t aware of the potential licensing issues, they might unintentionally breach the license agreement.
  5. Inadequate Auditing: Regular audits are key to maintaining compliance. Oracle LMS scripts can detect active and historical use, helping identify and rectify non-compliance issues.

By being aware of these potential pitfalls, companies can better manage their Oracle Advanced Compression licenses, ensuring they remain compliant and avoid unnecessary costs.

The Features of Oracle Advanced Compression

what is advanced compression

Oracle Advanced Compression is a powerful tool that comes with a wide array of features. These features are designed to automate Information Lifecycle Management (ILM), helping organizations maintain data usage statistics and set automatic data compression and movement policies.

Let’s break down these features for a better understanding:

  1. Advanced Row Compression: This feature helps to minimize the space required to store data in a row format.
  2. Advanced LOB Compression: Large Objects (LOBs) can take up significant space. This feature compresses them to save storage.
  3. Advanced LOB Deduplication: This feature eliminates duplicate LOB data to further optimize storage.
  4. RMAN Backup Compression: This feature compresses backup data. The ‘RMANDEFAULT COMPRESS’ setting does not require the Advanced Compression option.
  5. Data Pump Data Compression: This feature compresses metadata during data pump operations. Using the ‘COMPRESSION=METADATA_ONLY’ setting does not require the Advanced Compression option.
  6. Heat Map: This feature tracks data usage, providing valuable insights for managing data storage and lifecycle.
  7. Automatic Data Optimization: This feature optimizes data storage and compression based on usage patterns and pre-set policies.
  8. Data Guard Redo Transport Compression: This feature compresses data during redo transport operations, reducing network bandwidth requirements.
  9. Advanced Network Compression: This feature compresses network traffic, improving network efficiency.
  10. Optimization for Flashback Data Archive History Tables: This feature optimizes storing historical data in Flashback Data Archive tables.
  11. Storage Snapshot Optimization: This feature optimizes creating and managing storage snapshots.
  12. Online Move Partition: This feature lets you move partitions online to any compressed format.
  13. Exadata Flash Cache Compression: This feature compresses data in the Exadata Flash Cache. Note that it requires Exadata storage servers and all database processors accessing the Exadata storage servers to be licensed for Oracle Advanced Compression.
  14. Advanced Index Compression: This feature compresses indexes, reducing their storage footprint.
  15. Hybrid Columnar Compression Row-Level Locking: This feature provides row-level locking for hybrid columnar compressed data. It requires Exadata, Supercluster, ZFS, or FS1 storage.
  16. Data Pump Compression Feature: This feature compresses data during data pump operations.

Database Administrators (DBAs) must ensure they are properly licensed when using these features. This helps avoid any compliance issues.

Understanding and effectively managing your Oracle Advanced Compression features can lead to significant storage savings and improved efficiency.

Understanding Oracle Advanced Compression and DataPump

Oracle Advanced Compression and DataPump license

Oracle Data Pump is a handy tool in Oracle Database. Think of it as a personal courier service for your data, helping to move data and metadata between databases.

But here’s the catch: Oracle Data Pump might unintentionally activate the Advanced Compression option.

This is a separate feature of Oracle Database that offers enhanced data compression capabilities and requires a separate license.

Why does this happen?

The reason lies in Oracle Data Pump’s compression methods. It reduces the size of dump files during data transfer. Setting the “compress” parameter to “all” triggers the Advanced Compression option.

So, if you’ve used this set but don’t have a license for Advanced Compression, you might accidentally violate your Oracle license agreement.

Remember, using Oracle DataPump with the setting COMPRESSION=ALL does require Advanced Compression.

How can you avoid this licensing pitfall?

  1. Understand Your Parameters: Be aware of the implications of the parameters you’re using with Oracle Data Pump. If you don’t have an Advanced Compression license, To avoid triggering a license for advanced compression when utilizing Data Pump, you need to use the parameter MetaData_Only.
  2. Verify Your License: Know what Oracle options your license covers. If you’re unsure, don’t hesitate to contact your Oracle licensing consultant.
  3. Educate Your Team: Make sure everyone in your organization who works with Oracle Data Pump knows about this licensing issue. The more they know, the less likely they are to unintentionally breach the license agreement.
  4. Audit Regularly: Oracle LMS scripts can detect both active and historical use. Redress Compliance can help you identify and resolve noncompliance issues in your Oracle database.

By following these guidelines, you can use Oracle Data Pump effectively while avoiding unintentional activation of the Advanced Compression license. This ensures your Oracle licensing remains compliant and your budget stays intact!

Watch Out for Known Bugs That May Lead to False Positives in Oracle Audits
