A have some step by step description where downloading of OracleXEUniv.exe is one step.
But I cannot find what is it for? What is functionality of this file?
Than you.
OracleXE is the free version of Oracle's main database product. The "Universal" simply means it will install using the Universal character set instead of the Western European character set.
Oracle Database Express Edition (Oracle Database XE) is an
entry-level, small-footprint database based on the Oracle Database.
It's free to develop, deploy, and distribute; fast to download; and
simple to administer.

Our production Oracle Database version is 10g.
I am trying to install either 11g or 12c on my local machine primarily to access sqlldr.
I am wondering if there are any compatible issues.
Metalink has the definitive client/ server compatibility matrix. It will depend on the full version of the target database. Assuming "10g" means 10.2.0.2 or later, you should be fine with a 12.1 client. If the database is running something earlier than that, you'd generally need an earlier version of the client to be safe.

I'm using mysql as xampp(linux) component for my development works for a long time. But I wonder if I can use Oracle as my database. If I can which version should I choose that will fulfill my needs of production level development.
Also I've heard Oracle EE requires money for licensing. What facility they provide by licensing Oracle DB? Can it be used for development?(I'm just curious)
Oracle provides Oracle XE (Express edition) free for developer use which allows you to create and use databases of up to 4GB, use up to 1GB of RAM and use only one CPU. Anything more you gotta pay for it

I have a 4 Core 12GB RAM dedicated windows machine.I have Oracle 11g installed on it.
Could any body please help on the DB server parameters that can be tuned from a performance perspective.
Any reference to a credible url also is fine & will be of great help. Thanks..
Oracle provides a lot of online documentation including a lot of guides. The 2 Day DBA Guide for 11.2 has a section on Monitoring and Tuning the Database that can get you started. Other sections in the guide can be helpful as well.

The java version of my oracle database is 1.5.0_10.
How do I upgrade it to java 1.7.0_10
Thanks
It's not possible; Oracle supplies a certain version of Java with a certain version of the DBMS, specially modified to run "within" the DBMS. It can only be upgraded by Oracle as part of a new version or a patch release of the DBMS.
See for example this discussion: https://forums.oracle.com/forums/thread.jspa?threadID=2300779
If you mean the internal JVM, I believe that it is not upgradeable.

My current employer wants to use JavaDB for his new project. Allright with it, as my favoured SQLite isn't working very well with java and I, er..., don't really feel like arguing about it. Anyway I can't find a decent free tool to manipulate JavaDB or Derby databases. All I have is Netbeans. I've tried others but all the free ones are really tame tools and the pricy ones are good, but my employer doesn't want to pay a dyme (......).
Suggestions?
Perhaps http://squirrel-sql.sourceforge.net/ ?
Been looking for one too. I'm currently eying on this one http://www.razorsql.com
