title: DCM4CHEE Linux/Oracle installation
body: <p>I'm new to PACS and Dcm4chee installation.
  I try to install DCM4CHEE but I get some error on startup/login (
  dcm4che2.18+dcm4chee-arr-3.0.12 , Linux , Oracle DB)</p>
  
  <ul>
  <li>when I startup JBoss into server.log i see this message </li>
  </ul>
  
  <blockquote>
    <p>javax.persistence.PersistenceException:
    org.hibernate.HibernateException: Missing column: code_version in
    ARR.CODE</p>
  </blockquote>
  
  <p>I'm looking for DDL of table CODE and I saw that the column is defined in create.ora (dcm4che2.17) but not in create.ddl (dcm4chee-arr-3.0.12)</p>
  
  <ul>
  <li>If I login to dcm4chee-web3 (<a href="http://localhost:8080/dcm4chee-web3/" rel="nofollow">http://localhost:8080/dcm4chee-web3/</a>) on server.log I get this message </li>
  </ul>

  <p>Does anyone have any suggestions?</p>
  
  <p>Which version is recommended? Dcm4che 2.18+JBoss 4.2.3 (old) or Dcm4che 3.x+JBossAS7. On internet I found a lot of documentation on 2.17 installation, but none on 3.</p>
  
  <p>Thanks</p>
