Database Options

The following optional database options can be purchased separately. These options are only available with the Enterprise Edition (the only exception is RAC):

Partitioning Option

The partitioning option allows DBAs to split large tables into more manageable sub-tables (partitions). Some of the advantages offered:

  • Partitions can be stored in different tablespaces;
  • Partitions can be added/ removed while users are working;
  • Data can be selected from targeted partitioned without having to scan all partitions for rows (partition pruning).

Spatial Option

The Spatial option store geographical information (GPS coordinates for instance) with records.

Real Application Clusters Option

Real Application Clusters (RAC) - formerly called Oracle Parallel Server (OPS) - allows more than one instance to mount and open an Oracle database. RAC can only be used on special clustered systems.

Advanced Security Option

Oracle Advanced Security (ASO), formerly called the Advanced Networking Option, provides a suite of security features to protect a company's network by providing network encryption, authentication solutions, single sign-on services, and support for other security protocols. ASO is only available with Oracle Enterprise Edition.

Oracle Label Security

Row level security based on stringent government and commercial requirements; sensitivity labels (i.e. confidential, doctor-patient only, top secret) provide better intellectual property protection and privacy.

Oracle OLAP

Oracle OLAP is a complete set of analytical functions fully integrated within the database.

Oracle Data Mining

Oracle Data Mining offers embedded data mining for classifications, predictions, and associations to build advanced business intelligence applications.

Database Vault

A new option to Oracle Database 10g Release 2 Enterprise Edition that lets you control who, when, and where data and applications can be accessed, protecting against the most common security threat like malicious internal users.

Total Recall

Total Recall is based on Oracle's Flashback feature and will allow users to query data "AS OF" an earlier time in the past. This will allow companies to "archive" data for auditing and regulatory compliance. For more info, see Oracle Total Recall.

Advanced Compression

Option used to compress data. For more info, see Oracle Advanced Compression.

Real Application Testing (RAT)

RAT can be used to capture, analyze and replay database transactions. For more info, see Real Application Testing.
