Career plan

I'm into software proffession since last 7 years. In all these years i do performance testing using tools like Load Runner, Performance Monitoring using Topaz and Oracle performance Tuning. I'm OCP 8i also. Since last 1-2 tears my job involves less Oracle performance tuning activities now.

Now i'm thinking of moving to Orale DBA. Can anybody suggest if i do Oracle 10g certification it'll be easier to convince me to get the DBA job or my previous experince in in Oracle and 8i certification more than enough. For info, i'm pretty confident with most of the DBA jobs except Backup Recovery as never required to do that in my career.
