    Oracle Advanced Compression Option - Effect On RMAN Backup

    987230
      My client is interested in introducing Oracle's Advanced Compression capabilities into their 11g landscape. My questions are related to the effects RMAN Compression has on backup infrastructures. I need to understand the impact/reduction in Data Domain or tape that can be expected.

      1. What has been the experience with implementing RMAN Compression? Are there any lessons learned you can share?
      2. There are three levels of compression -- LOW, MEDIUM & HIGH. What compression ratios have you seen for any/all of these levels?
      3. Have you experienced any effects on server performance or any impact on database and backup functionality, when RMAN Compression is running?

      I would appreciate any insights you can share.
