  • Make a backup!!!
  • Stop Tomcat
  • Edit OpenKM.cfg and set hibernate.hbm2ddl to update
  • Replace the OpenKM.war
  • Review file descriptor limit and, eventually, increase it.
  • Run from your preferred SQL client these queries:

HSQL 

ALTER TABLE OKM_NODE_NOTE alter column NNT_TEXT clob;

MySQL 

alter table OKM_NODE_NOTE modify NNT_TEXT longtext;

PostgreSQL 

alter table OKM_NODE_NOTE alter NNT_TEXT TYPE text;

Oracle 

alter table OKM_NODE_NOTE modify (NNT_TEXT clob);

If the ALTER TABLE sentence fails in Oracle with ORA-22858, you have another way: 

alter table OKM_NODE_NOTE add NNT_TEXT_TMP CLOB;
update OKM_NODE_NOTE set NNT_TEXT_TMP = NNT_TEXT;
alter table OKM_NODE_NOTE drop NNT_TEXT;
alter table OKM_NODE_NOTE rename NNT_TEXT_TMP to NNT_TEXT;
  • Start Tomcat again
  • Check for database errors:
$ grep "ERROR .*hbm2ddl" $TOMCAT_HOME/logs/catalina.log
  • Go to Administration > Scripting and execute this script:
// com.openkm.dao.NodeBaseDAO.getInstance().fixNodePath();
import org.hibernate.HibernateException;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.Transaction;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import com.openkm.core.DatabaseException;
import com.openkm.dao.bean.NodeBase;
import com.openkm.dao.HibernateUtil;
import com.openkm.core.Config;

Logger log = LoggerFactory.getLogger("com.openkm.migration");
int count = 0;

void fixNodePathHelper(Session session, NodeBase parentNode) throws HibernateException {
	String qs = "from NodeBase nb where nb.parent=:parent";
	Query q = session.createQuery(qs).setCacheable(true);
	q.setString("parent", parentNode.getUuid());
	
	for (NodeBase nb : q.list()) {
		nb.setPath(parentNode.getPath() + "/" + nb.getName());
		session.update(nb);
		log.info("Updated node: {}", nb.getPath());

		if (count++ % 100 == 0) {
			HibernateUtil.commit(session.getTransaction());
		}
		
		// Process in depth
		fixNodePathHelper(session, nb);
	}
}

log.info("***** Process BEGIN *****");
String qs = "from NodeBase nb where nb.parent=:parent";
Session session = null;
Transaction tx = null;

try {
	session = HibernateUtil.getSessionFactory().openSession();
	tx = session.beginTransaction();
	
	// First level nodes
	Query q = session.createQuery(qs);
	q.setString("parent", Config.ROOT_NODE_UUID);
	
	for (NodeBase nb : q.list()) {
		nb.setPath("/" + nb.getName());
		session.update(nb);
		log.info("Updated node: {}", nb.getPath());
            
		// Process in depth
		fixNodePathHelper(session, nb);
	}
	
	HibernateUtil.commit(tx);
} catch (HibernateException e) {
	HibernateUtil.rollback(tx);
	throw new DatabaseException(e.getMessage(), e);
} finally {
	HibernateUtil.close(session);
}

log.info("***** Process END *****");

To see the progress: 

$ tail -f $TOMCAT_HOME/log/catalina.log
  • Translation property "fileupload.send" has been changed to "fileupload.button.send" so, you can remove the old one:
delete from OKM_TRANSLATION where TR_KEY='fileupload.send';
  • Enjoy OpenKM 6.2.7!

If you have any weird problem try to stop Tomcat, delete these folders:

  • $TOMCAT_HOME/webapps/OpenKM
  • $TOMCAT_HOME/work/Catalina/localhost

And start Tomcat again.
