Hi Prakash
  I had similar issue few years ago. Due to a script bug, one of my colleague moved files to incorrect file names (In fact, even file names were exchanged! ), causing very similar issue.

  You might want to dump the file_hdrs and that should show file names in the trace file. Then move those files to correct file names.

oradebug setmypid
oradebug dump file_hdrs 15
