Saida,
LKBrwnDBA is absolutely correct...You wouldn't want a surgeon suggesting liver surgery just because your symptoms are that you "don't feel well and have a fever."

...my boss asked me to solve a situation that involves Oracle, since there's no one else around to do it.
If there is no one else around to solve the situation, why didn't s/he solve the problem her/himself? If s/he didn't solve it her/himself because s/he doesn't know anything about Oracle databases, then why is your expertise any better than her/his?
This is similar to people not paying for auto insurance, getting into an accident, then expecting "someone else" to pay for the accident besides themselves. If your boss is willing to pay nothing for Oracle expertise, then s/he gets what s/he pays for..."nothing".
We cannot diagnose a problem for which we have no more insight than what you have given us. When you say that you "...feel like an alien on earth," we feel similar...we are aliens to you code since we have no access to your code to isolate and troubleshoot your problem. Your boss needs to round up her/his shoulders and pay for an Oracle professional to help...you could become the "Oracle professional" yourself, but that takes training and time (neither of which you can afford under your emergency circumstances)...if you cannot become a trained "surgeon" in this emergency, yet you have been thrown into the "MASH Unit" to do the surgery, then your boss must be prepared to "lose the patient".
There are probably many Oracle professionals that can look at your code, troubleshoot, and solve your problem. Such professionals can do their work either on-site or remotely, but they will cost some money.
Sorry to be the bearer of bad news, but we would be "Malpracticing" if we suggested solutions without more facts.
