I am using Linux operating system. My application run on Java and Oracle is my Database.
In my /ora2/DB/archive folder I have increasing log files written which have occupied 85% of the filesystem now.

I have so many .arc files in /ora2/DB/archive with names like DB1_5218.arc etc. each occupying atleast 20 MB. I have atleast 100 .arc files written in a day.

What makes .arc files written?

Why such a Huge load of files in archive folder?

I am new to oracle logs , does too many threads running for a database operation and database not committed, closed or rolledback in the end cause these many files to be written in the archive?

Please help.

    There is a very complete explanation in the documentation here: http://docs.oracle.com/cd/B19306_01/server.102/b14231/archredo.htm

    Briefly, these are backups of the redo log files generated by database changes. They are used for recovering the database from a media failure. They can also be “consumed” by another database acting as a failover.
