Secure Distributed Transaction Recovery Background Process (RECO)
Oracle AI Database enables queries and DMLs on objects hosted on a different database. When objects are updated on a remote database, the transaction on the source database ends up becoming a distributed transaction. If a distributed transaction fails, a database background process (RECO) periodically tries to re-establish contact, with the yet-to-be-notified subordinates and pushes the final outcome to those remote databases.
Secure Distributed Transaction Recovery Background Process (RECO) provides additional security for the RECO process.
IP Rate Limit in CMAN
You can use Oracle Connection Manager (CMAN) to limit the number of new connections allowed from an IP address in the specified unit of time. This IP rate limit feature enables you to protect your database against potential denial-of-service (DoS) attacks.
Malicious clients can send excessive connection requests to the server node. This can saturate the capacity of CMAN to handle new connections per second, and thus cause DoS attacks on your database. Using this security feature, you can prevent these types of attacks by detecting such clients early and rejecting those connections.
Enhancements to Oracle Data Redaction
This release includes many enhancements to Oracle Data Redaction, such as the optimization of existing capabilities and the removal of previous limitations.
These enhancements to Oracle Data Redaction improve the overall experience.
OCI Attributes for Microsoft Azure Active Directory Integration with Additional Oracle AI Database Environments
You can log into additional Oracle AI Database environments using your Microsoft Azure Active Directory (Azure AD) single sign-on OAuth2 access token. The previous release supported Azure AD integration for Oracle Cloud Infrastructure (OCI) Autonomous Database (Shared Infrastructure). This release has expanded Azure AD integration to support on-premises Oracle Database 19c release 19.16 and later. The project adds the OCI attributes needed to supply the bearer token for connection creation.
This multi-cloud feature integrates authentication and authorization between Azure AD and Oracle AI Databases in Oracle Cloud Infrastructure and on-premises.
Verifying Digital Signature and Integrity of Installation Archive Files
In Oracle AI Database 26ai, Oracle digitally signs the installation archive files with Oracle certificates.
Oracle digitally signs the installation archive files to allow customers to ensure the integrity of the packages before deploying them in their environments.
