RMAN for Oracle Database 19c Part II : Problem-Solution-Explanation Part II

What skills set the database administrator (DBA) apart from other technologists? Of the many responsibilities laidupon a DBA which cannot be performed by someone else? Adding database accounts? Creating tables and indexes?Installing and configuring databases? Optimizing the database and the applications that access and manipulate it?All of these things are regularly performed by people who do not consider themselves database administrators.They consider themselves to be programmer/analysts to be application developers to be managers and directorsand they do all these things just to be able to move forward with their own job. Most application developers knowhow to run the Oracle Universal Installer—it’s just another graphical application and these days accepting all thedefault choices is a perfectly valid way to get the job done. Adding database accounts? That’s easy! Granting databaseprivileges? Just give ’em “DBA” or “SYSDBA” and no more problems! Creating tables and indexes? C’mon that’s moreof a developer’s job than the DBA’s job isn’t it? Tuning Oracle databases is mostly about crafting efficientSQL statements and while this job often falls to DBAs it is best handled by the developers and programmers whowrite the SQL in the first place.
