Knowledge:Migration from 6.2.6 to 6.2.7

• See changelog at Mantis

• Download update from http://openkm.com/download/okm/OpenKM-6.2.7.zip (eMpg8eIjY5)

• 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

• Set installation customer at License Manager.

• Go to Administration > Scripting and execute this script:

        }
    }

        // Process in depth
        fixNodePathHelper(session, nb, 1);
    }
    
    HibernateUtil.commit(session.getTransaction());
} catch (HibernateException e) {
    HibernateUtil.rollback(session.getTransaction());
    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.
