title: ORA-04045: errors during recompilation/revalidation
body: <p>I just suddenly started getting this error when trying to query the table AVC.</p>
  
  <pre><code>ORA-04045: errors during recompilation/revalidation of PUBLIC.AVC
  ORA-04098: trigger 'TTMS.ALTERED_TTMSDB_TABS_TRIGGER' is invalid and failed re-validation
  </code></pre>
  
  <p><code>select * from avc</code> doesnt work
  but <code>select * from exfc.avc</code> does work.</p>
  
  <p>Can anyone tell me what is going on?</p>
