No degree

I 'tried' the computer field and still want to at some point, but guess what, I'm not experienced enough for anyone to consider me for a job in that field. But to prove your ability I need certification credential in my current job. From now we'll start work on linux, but work is over all of database management. I think currently for OCP-DBA certification. If I would need of linux, then I'll go for it simultaneously. But the one thing is I've not much time to spend on study. I need certificates to raise my levels and to earn more. OCP certification will give me big job opportunities, i had called here. I'm in hurry suggest me some relevant stuff, which can make sure me to get pass.
Any information is welcomed.
