Enable and Disable Application Continuity
Change the failover type on Autonomous Database using the DBMS_CLOUD_ADMIN
procedures to enable or to disable
Application Continuity. New sessions use the new failover type from the time when you modify
the current value.
Application Continuity masks outages from end users and applications by recovering the in-flight work for impacted database sessions following outages. Application Continuity performs this recovery beneath the application so that the outage appears to the application as a slightly delayed execution.
See Overview of Application Continuity for more information on Application Continuity.
Enabling Application Continuity requires Oracle Client software version 18.3 (or higher).
Application Continuity is enabled on a per database service level. You supply a
value for the service_name
.
Note:
By default Application Continuity is disabled.If Application Continuity is enabled and you want to disable Application Continuity,
use DBMS_CLOUD_ADMIN.DISABLE_APP_CONT
.
For example, if you enabled Application Continuity in the service named
nvt21_adb1
_high
and you want to disable
Application Continuity for this service, run the following command:
BEGIN
DBMS_CLOUD_ADMIN.DISABLE_APP_CONT
(
service_name => 'nvt21_adb1_high.adb.oraclecloud.com'
);
END;
