Hi friend,

As you know that market is poor now, however my kind
suggestion is that please learn Unix shell scripting also.

You must have good exposure in SQL and PL/SQL and unix , if
you have idea about Oracle forms & reports it is added
advantage.

If possible please get certified in OCA and OCP.

If you have any queries do mail to prasadreddi_mca@yahoo.com

Thanks
