title: IBM DB2 unable to access database from PYTHON after reboot
body: <p>I was working in DB2 from jupyter-notebook in this way
  SO: Windows10 python 3.8 and the library ibm_db: version 3.0.1</p>
  <pre><code>dsn = &quot;DRIVER={{IBM DB2 ODBC DRIVER}};&quot; + \
    &quot;DATABASE=BLUDB;&quot; + \
    &quot;HOSTNAME=dashdb-xxxxxxxxxal.bluemix.net;&quot; + \
    &quot;PORT=50000;&quot; + \
    &quot;PROTOCOL=TCPIP;&quot; + \
    &quot;UID=xxxxxxx;&quot; + \
    &quot;PWD=p^xxxxxxx;&quot;
  hdbc  = ibm_db.connect(dsn, &quot;&quot;, &quot;&quot;)
  </code></pre>
  <p>but I decided to restart the connection and i can't connect anymore</p>
  <p>this returns the next message</p>
  <blockquote>
  <p>----&gt; 1 hdbc  = ibm_db.connect(dsn, &quot;&quot;, &quot;&quot;)</p>
  <p>SQLCODE=-5005on: [IBM][CLI Driver] SQL5005C  The operation failed because the database manager failed to access either the database manager configuration file or the database configuration file.</p>
  </blockquote>
