I am from India. I have been working for last 6 years in php-mysql.
Now I want to switch to Oracle.Oracle supplies MySQL, it is one of the about 7 database types that Oracle Supplies.
Please suggest me some industry oriented and demanding certification courses so that I can get a job easily.'..... so that I can get a job easily.'
...switch over my career to the Oracle apps?'Oracle apps' tends to imply Oracle Applications, which are things like Peoplesoft, the eBusiness Suite and other applications that run on an Oracle database. However, you indicated that you have been working in php-mysql, which indicates you have been working in Web application development. The closest Oracle equivalent to that in my opinion would likely be development in Application Express. If that is the direction that you want to go, then you'd be interested in the PL/SQL certification and probably the Expert certification in Application express.
