"U" isn't available, "U" is dead as far as I know. Look it up, it is true.
http://en.wikipedia.org/wiki/U_of_Goryeo But that said, I can help. I can tell you that using "text messaging speak" like "u" and such makes you sound like a 12 year old. It is not very professional and will get you laughed at (only you won't know you were laughed at since the companies you try to get employment with simply won't contact you).
So, I would work on the communication skills - something very important as you approach people to ask them for opportunities. You never know what the person on the other end of the communication line will think of you - unless you approach them with a degree of professionalism from the very beginning.
Using full words - not "text messaging speak". Things like that are oh so very important.
That is the extent of my help - you can check oracle.com for job postings, we have a job website (click on careers from the home page) there.
