No one can response this query for sure, because you are asking for a forecast about what will occur later on, not about some particular part of present technological innovation. No response that you get – such as my own – can be known as “right” until the approved (although the one that demands that Oracle “is” A linux systemunix is unconditionally wrong).
The need for “data” and, therefore, some kind of information source, is only improving, but so are the phone calls of professionals who say that a new kind of application is required to handle that information (see associate weblink below). In other terms, someone who focuses primarily on Oracle – and does not strategy in advance by maintaining up with growing styles in more recent information source technological innovation – might discover fewer possibilities over time. Add to that the heavy price of Oracle application (which places some boundaries on their client base) and you have a market which is not likely to develop much.
Linux is seen as low-end in comparison to other *NIX versions, but it is very typical, is relatively new OS technological innovation, and is still under effective development by a variety of providers. All technological innovation will gradually age and vanish – or at least develop into new types – but Working Techniques usually have a longer period efficient lifestyle than programs application. Concentrate on protection control, or server implementation in a VM atmosphere, and there are a lot of possibilities.
If your query is comprehended properly, then It can be believed that you might discover more opportunities – and longer-lasting job prospective – in the A linux systemunix Administration place than in RDBMS technological innovation, Oracle or otherwise. Eventually, if you don’t appreciate one or the other of these choices, then choosing the one with “better upcoming scope” only lock you in to a longer period phrase in a distressing profession, so definitely consider doing what you like, especially if you are excellent at it. If you do not have the abilities to do it well, then you won’t get far in either situation. Skills can be discovered, information can be obtained, but abilities are built-in.
If you are asking about making prospective, then it can be said that an excellent DBA creates as much as or more than a linux systemunix SA, based upon available on the market and other abilities. Also, neither of this technological innovation seems likely to vanish over night or to modify very easily, so there will be sufficient a chance to evolve or even modify profession routes, whichever one you select.
