SAP deployed with Delphix

Oracle DBA Training Options Are Changing

Oracle DBA Training Options Are Changing

Training options for Oracle Database DBAs are changing. Generally, I don't think they are for the better. Companies don't value Oracle Database Administrators like they used to. And, it shows in the lack of their professional development investment.
