Continuous Availability
Application Continuity Session State Restore with Database Templates
Application Continuity uses database templates to checkpoint the session state, restore the session state at the start of replay, and support session migration during planned maintenance. Database templates restore server-side and client-visible session states at the beginning of the Application Continuity replay, thus increasing Application Continuity protection.
Application Continuity with Database Templates broadens and simplifies the use of Application Continuity to reduce planned maintenance-related downtime. It also enables the migration of more sessions faster during unplanned outages, ensuring higher levels of protection.
Enhanced Upgrade of Time Zone Data
The process of upgrading timezone data to reflect up-to-date Governmental Daylight Saving Time rules is optimized, taking the actual data content of tables into account. Only tables impacted by a Daylight Saving Time rule change will undergo a data change.
Optimizing the necessary data changes for a Daylight Savings Time rule change significantly improves the overall upgrade of timezone data to the absolute bare minimum to bring a database up to the latest global timezone rules. The implicit analysis and reduction of the data required to change significantly reduces the overall timezone upgrade process and the resources needed.
Optimized Read-Write Operations for Database Processes
To optimize the read and write operations performed by database processes when you access files managed through OFS or DBFS, specify the new db_access mount option for the dbms_fs.mount_oracle_fs procedure while mounting the file system.
When you enable db_access, both memory consumption and CPU usage reduces. The throughput increases while performing read and write operations by database processes on the files managed by OFS.
Smart Connection Rebalance
Smart Connection Rebalance transparently reshuffles service-based connections based on real-time performance monitoring across Oracle Real Application Clusters (Oracle RAC) instances.
Smart Connection Rebalance improves database performance by automatically moving sessions across Oracle RAC database instances without needing manual intervention.
Smooth Reconfiguration of Oracle RAC Instances
The smooth reconfiguration feature reduces the brownout time caused by certain Oracle Real Application Clusters (Oracle RAC) operations, such as nodes joining or leaving an Oracle RAC cluster.
Smooth Reconfiguration of Oracle RAC Instances ensures continuous availability of Oracle RAC services and reduces brownout time for database instances running in an Oracle RAC database.
Support for the Coexistence of DGPDB and GoldenGate Capture
This project introduces perPDB DataGuard. When DGPDB is configured on a source/Primary database, there are validations that insure there is no GoldenGate Capture pre-existing on the source. GoldenGate capture sessions will be broken if a DGPDB is allowed and executes a role transition.
This project adds support for coexistence of DGPDB and GoldenGate Capture. Changes/support will be required in the LogMiner, redo transport, and Broker layers.
