Changing Persistence Provider Parameters

PREVIOUS NEXT

You can change the persistence provider parameters using a configuration property.

To change the parameters of the persistence provider property:

Open the RAR deployment descriptor using any text or XML editor.
Locate the property name <config-property-name>persistenceProperties</config-property-name>.
Replace the default value of <config-property-value>JNDI_NAME=jdbc/bresdatasource</config-property-value> (database persistence in J2SE where the JNDI name is jdbc/bresdatasource) with one of the following:

<config-property-value>DIRECTORY=res_data

</config-property-value> (file persistence)

Where the path to the top directory containing rulesets is res_data.

<config-property-value>

DRIVER_CLASS_NAME=com.pointbase.jdbc.jdbcUniversalDriver,URL=jdbc:pointbase:server://computer/database,USER=pbpublic,PASSWORD=pbpublic

</config-property-value> (database persistence in J2SE)

Where:

DRIVER_CLASS_NAME: A driver implementation class to establish a connection with the database.

URL: The JDBC URL to establish a connection with the database.

USER: Login to use with the database connection.

PASSWORD: A password to use with the database connection.

For both persistence types, the property CONCURRENT_PERSISTENCE_ACCESS specifies whether persistence access can be concurrent.

To add the property to the ruleset provider configuration, include the property name as follows:

J2EE database persistence

<config-property-value>
   JNDI_NAME=jdbc/bresdatasource
   CONCURRENT_PERSISTENCE_ACCESS=false
</config-property-value>

J2SE database persistence

<config-property-value>
      DRIVER_CLASS_NAME=com.pointbase.jdbc.jdbcUniversalDriver,
      URL=jdbc:pointbase:server://computer/database,
      USER=pbpublic,
      PASSWORD=pbpublic,
     CONCURRENT_PERSISTENCE_ACCESS=false
</config-property-value>

File persistence

<config-property-value>
   DIRECTORY=res_data,
   CONCURRENT_PERSISTENCE_ACCESS=false
</config-property-value>
