title: IMP-00403 while executing IMP command
body: <p>I am getting <code>IMP-00403:</code> error and a separated <code>sql</code> file while executing <code>IMP</code> command. I am executing it as <code>IMP system/password fromuser=A touser=A</code>. I read that I should execute this sql file <code>catexp.sql</code> before performing this operation and I did that, but the problem still occurs. I checked the database user roles and I cannot find the <code>IMP_FULL_DATABASE</code> role for user <code>SYSTEM</code> but only for <code>SYS</code>. </p>
