I have got 1.5 yr. exp. on Oracle 9i (SQL and PL-SQL).
Now I have entered in JAVA
It's spelled, "Java".
These days Sun calls it, "JEE".
I am going to give certification SCJP and OCA(9i).
Oracle's RDBMS is up to version 11. I'm not sure what "OCA" is - some
Oracle-specific acronym?
Could you suggest me Is this combination will help me get better job.
I suggest that you study the current versions of these products for your
certifications, not old versions.
What is the future tecnology that suites above combination
Catching up with the present technology would be good. Knowing the correct
spellings of your buzzwords will help you get the job - I would hesitate to
hire a Java programmer who can't spell the name of the language correctly.
Java and Oracle are good things to know. Bear in mind that Oracle, like all
SQL-based RDBMS products, deviates from the SQL standard in certain ways.
Learn at least one more database system, say, PostgreSQL (a.k.a., "Postgres").
It's free. Learn the current version of Oracle - their "Oracle Express"
version is free of fees to use and deploy.
Keep current with Java, too - it's up to version 6 now.
Getting the better job is not just about knowing one or two languages. You
need to market yourself effectively to potential employers. This involves
mostly your listening and other "people" skills, much more than your
technical. You not only have to have the technical ability but show employers
that you can use that for their specific needs.
Nearly every applicant for every job you want is technically qualified for the
job. You're going to win on the strength of how committed you appear, how
hard working, how ready to put up with their crap.
