title: Archive files with .arc extension is growing extremely in oracle database
body: <p>I am using Linux operating system. My application run on Java and Oracle is my Database.
  In my <code>/ora2/DB/archive</code> folder I have increasing log files written which have occupied 85% of the filesystem now.</p>
  
  <p>I have so many .arc files in <code>/ora2/DB/archive</code> with names like <code>DB1_5218.arc</code> etc. each occupying atleast 20 MB. I have atleast 100 .arc files written in  a day.</p>
  
  <p>What makes .arc files written?</p>
  
  <p>Why such a Huge load of files in archive folder?</p>
  
  <p>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?</p>
  
  <p>Please help.</p>
