Programming Languages

Don't be an "X developer". You're selling yourself short, if you define yourself by the technology you most frequently use. If you want a great career as a developer, you need to be well versed in a bunch of different technologies. The best developers I know are effective at multiple layers of the stack. They write code in high-level languages such as Python, drop down to C for performance-intensive stuff, are familiar with HTML, CSS and JavaScript, know when to pick up a new technology like Varnish or Solar, know how to set up a Linux server, know how DNS works, tinker with Objective-C on the side. There is nothing wrong with specializing in one particular programming language, but don't let it define you. The more strings you have in your bow the easier you'll find it to land your ideal job (and the more you'll be able to charge for your services).

Oracle DBA will definitely be in action as long as the databases are there. But, we need to keep improving our self and update with the latest technologies. For example as of now, traditional DBA work is minimal as the databases itself has convenient monitoring and alert systems (Oracle Enterprise Manager). All the work which DBA used to do manually are now automated with this solution. Some of the things you can involve yourselves with are database design, performance optimizations, and architecture and building solutions catered to specific requirements. You could spend years just master a few of these skillsets. There are over 312 Databases courses in India.
