Hi
As a developer, I want to start using DBMS_SCHEDULER in Oracle DB 19c.
However, our DBA is against it and provided the following reasons: Oracle database should not be used as a scheduling server because it could impact maintenance. If the platform wants to perform maintenance and closes the listener to prevent customer sessions from changing data, it would be possible to flashback the database to the state at the "beginning of maintenance." If scheduler jobs are allowed, then the database could initiate data changes (including remote calls), which would cause data loss if a flashback is needed after a failed maintenance task.
Are the claims made by the DBA accurate?
