title: Premature Redo Log Switching in Oracle RAC
body: <p>What are the possible causes of premature redo log switching in Oracle other than reaching the specified file size and executing <code>ALTER SYSTEM SWITCH LOGFILE</code>?</p>
  
  <p>We have a situation where some (but not all) of our nodes are prematurely switching redo log files before filling up. This happens every 5 - 15 minutes and the size of the logs in each case vary wildly (from 15% - 100% of the specified size).</p>
