<source lang="sql">
−
<!-- hibernate dialect -->

SHOW FULL TABLES FROM okmdb;
−
<property name="hibernate.dialect">org.hibernate.dialect.HSQLDialect</property>

<source lang="xml">
+
<source lang="sql">

<!-- hibernate dialect -->
+
SHOW FULL TABLES FROM okmdb LIKE 'OKM_%'
−
<property name="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</property>

Download MySQL JDBC driver from MySQL Home Page and move it to $TOMCAT_HOME/lib or $JBOSS_HOME/server/default/lib depending on your OpenKM version..


Nota clasica.png If you get an error like this: 
Packet for query is too large (1708726 > 1048576).
You can change this value on the server by setting the 'max_allowed_packet' variable.
You need to modify your MySQL server configuration file and increase the value of the max_allowed_packet property. Don't forget to restart the MySQL after any change in this file. In Debian based distros like Ubuntu, this configuration file is located at /etc/mysql/my.cnf.

Change MySQL default engine to InnoDB

Check if your MySQL installation has InnoDB engin enabled: 

 $ mysql -h localhost -u root -p
 mysql> show engines;

In order to change the default storage engine edit /etc/mysql/my.cnf and under [mysqld] section in your ini file, and add: 

 default-storage-engine = innodb

Nota idea.png InnoDB is the preferred engine because it support transactions. MyISAM is more responsive but does not support transactions.

If you want to show which engine is using every table, do: 

SHOW TABLE STATUS WHERE name like 'OKM_%';

To see all the tables included in a database: 

SHOW FULL TABLES FROM okmdb;

You can also filter by table name: 

SHOW FULL TABLES FROM okmdb LIKE 'OKM_%'

Database repair

If you have problems with a database and need to be repaired, you can use this command: 

 $ mysqlcheck -u root -p --auto-repair --optimize --all-databases
