title: Can we add comments on index in oracle?
body: <p>I have one index in oracle say "TEMP_INDEX" and i want to add one comment on it like "OBSOLETE" so that i can ignore this index for further processing.</p>
  
  <p>Can we do this? or is there any other way to do this.</p>
  
  <p>Here the aim is, i just want to mark index in some way so that it won't be considered for further processing. Here the constraint is, i can't delete that index.</p>
