title: ORA-01084: invalid argument in OCI call goes away after iisreset
body: <p>There is no change in code or stored procedure since I changed it last 2 days back. 
  Everything was working fine. 
  Today when I executed same piece of code it started throwing </p>
  
  <blockquote>
    <p>"ORA-01084: invalid argument in OCI call".</p>
  </blockquote>
  
  <p>After 4-5 attempts when I restarted IIS it started working without any problem. </p>
