title: ORA-01000: maximum open cursors exceeded using oracle instant client and C#
body: <p>Our C# application is generating ORA-01000 error. We were using ODP.Net and the application was running just perfect without any ORA-01000 error. </p>
  
  <p>We removed the ODP.Net and installed the instant client instead (we are now connecting from C# to Oracle using 7 dll files which are oci.dll, ociw32.dll, Oracle.DataAccess.dll, orannzsbb11.dll, oraocci11.dll, oraociicus11.dll and OraOps11w.dll). </p>
  
  <p>Since then we are getting the ORA-01000 upon executing a long process with multiple queries. Noting that we are closing/disposing the OracleDataReader object.</p>
  
  <p>What could be the reason behind the ORA-01000 with instant client?</p>
