Knowledge:Oracle - OpenKM 5.1

In this OpenKM release you can create the databases automatically configuring the hibernate.dialect and hibernate.hbm2ddl properties in OpenKM.cfg.

hibernate.dialect=org.hibernate.dialect.OracleDialect
hibernate.hbm2ddl=none

In others databases Hibernate can create the tables automagically, but due to some Oracle mapping issues you should create the tables yourself. See Solving schema table creation problems for more info. We will fix this behabior in the next major OpenKM release.

This configuration property should be set before the database creation. Once the database has been initialized don't modify it because can damage your installation. If your OpenKM installation has been already configured with another database (default one is an embedded one called HSQL) you can't switch to another database simply changing this property.

More info about this at:

• Hibernate: SQL Dialects

Database creation

Starting with OpenKM 5.0, only one database is needed because there is no table name collision.

The right sequence is:

• Edit OpenKM.cfg and set:
  • hibernate.dialect=org.hibernate.dialect.OracleDialect
  • hibernate.hbm2ddl=none
• Edit and properly modify JBoss datasources.
• Edit and properly modify repository.xml
• Execute the table creation script.
• Execute the inserts to create a minimal environment (see next point)
• Start JBoss.

The application will create some tables related to Jackrabbit persistence, so the Oracle user should have the right permissions.

Solving hibernate schema creation problems

We've found some problems in default hibernate creation database script in okm_app database. It'll be needed to connect to database and make minimal changes and execute this script at File:Oracle-schema-okm-5.0.sql.

Also run these inserts to create a minimal environment:

insert into OKM_USER (USR_ID, USR_NAME, USR_PASSWORD, USR_EMAIL, USR_ACTIVE) values ('okmAdmin', 'Administrator', '21232f297a57a5a743894a0e4a801fc3', 'admin@noreply.com', 1);
insert into OKM_ROLE (ROL_ID, ROL_ACTIVE) values ('AdminRole', 1);
insert into OKM_ROLE (ROL_ID, ROL_ACTIVE) values ('UserRole', 1);
insert into OKM_USER_ROLE (UR_USER, UR_ROLE) values ('okmAdmin', 'AdminRole');
insert into OKM_PROFILE (PRF_ID, PRF_NAME, PRF_ACTIVE) values (1, 'Default', 1);

JBoss datasources

<local-tx-datasource>
    <jndi-name>OpenKMDS</jndi-name>
    <connection-url>jdbc:oracle:thin:@localhost:1521:sid</connection-url>
    <driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
    <user-name>openkm</user-name>
    <password>*****</password>
    <min-pool-size>5</min-pool-size>
    <max-pool-size>20</max-pool-size>
    <idle-timeout-minutes>28680</idle-timeout-minutes>
    <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name>
    <valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker</valid-connection-checker-class-name>
    <metadata>
        <type-mapping>Oracle9i</type-mapping>
    </metadata>
</local-tx-datasource>

This type-mapping applies both to Oracle 9i and Oracle 10g. Make sure that you have the latest Oracle 10g version of ojdbc14.jar. See also JDBC - Oracle FAQ. Read more about datasource configuration at Configuring JDBC DataSources.

The type mapping should match a type-mapping/name element from $JBOSS_HOME/server/default/conf/standardjbosscmp-jdbc.xml. Example configurations for many third-party JDBC drivers are included in the $JBOSS_HOME/docs/examples/jca directory.
