Quartz Enterprise Job Scheduler 1.x Configuration Reference

Configure DataSources

If you’re using JDBC-Jobstore, you’ll be needing a DataSource for its use (or two DataSources, if you’re using JobStoreCMT).

DataSources can be configured in three ways:

• All pool properties specified in the quartz.properties file, so that Quartz can create the DataSource itself.
• The JNDI location of an application server managed Datasource can be specified, so that Quartz can use it.
• Custom defined org.quartz.utils.ConnectionProvider implementations.

It is recommended that your Datasource max connection size be configured to be at least the number of worker threads in the thread pool plus three. You may need additional connections if your application is also making frequent calls to the scheduler API. If you are using JobStoreCMT, the “non managed” datasource should have a max connection size of at least four.

Each DataSource you define (typically one or two) must be given a name, and the properties you define for each must contain that name, as shown below. The DataSource’s “NAME” can be anything you want, and has no meaning other than being able to identify it when it is assigned to the JDBCJobStore.

Quartz-created DataSources are defined with the following properties:

Property Name	Required	Type	Default Value
org.quartz.dataSource.NAME.driver	yes	String	null
org.quartz.dataSource.NAME.URL	yes	String	null
org.quartz.dataSource.NAME.user	no	String	""
org.quartz.dataSource.NAME.password	no	String	""
org.quartz.dataSource.NAME.maxConnections	no	int	10
org.quartz.dataSource.NAME.validationQuery	no	String	null

org.quartz.dataSource.NAME.driver

Must be the java class name of the JDBC driver for your database.

org.quartz.dataSource.NAME.URL

The connection URL (host, port, etc.) for connection to your database.

org.quartz.dataSource.NAME.user

The user name to use when connecting to your database.

org.quartz.dataSource.NAME.password

The password to use when connecting to your database.

org.quartz.dataSource.NAME.maxConnections

The maximum number of connections that the DataSource can create in it’s pool of connections.

org.quartz.dataSource.NAME.validationQuery

Is an optional SQL query string that the DataSource can use to detect and replace failed/corrupt connections. For example an oracle user might choose “select table_name from user_tables” - which is a query that should never fail - unless the connection is actually bad.

Example of a Quartz-defined DataSource

org.quartz.dataSource.myDS.driver = oracle.jdbc.driver.OracleDriver
org.quartz.dataSource.myDS.URL = jdbc:oracle:thin:@10.0.1.23:1521:demodb
org.quartz.dataSource.myDS.user = myUser
org.quartz.dataSource.myDS.password = myPassword
org.quartz.dataSource.myDS.maxConnections = 30

References to Application Server DataSources are defined with the following properties:

Property Name	Required	Type	Default Value
org.quartz.dataSource.NAME.jndiURL	yes	String	null
org.quartz.dataSource.NAME.java.naming.factory.initial	no	String	null
org.quartz.dataSource.NAME.java.naming.provider.url	no	String	null
org.quartz.dataSource.NAME.java.naming.security.principal	no	String	null
org.quartz.dataSource.NAME.java.naming.security.credentials	no	String	null

org.quartz.dataSource.NAME.jndiURL

The JNDI URL for a DataSource that is managed by your application server.

org.quartz.dataSource.NAME.java.naming.factory.initial

The (optional) class name of the JNDI InitialContextFactory that you wish to use.

org.quartz.dataSource.NAME.java.naming.provider.url

The (optional) URL for connecting to the JNDI context.

org.quartz.dataSource.NAME.java.naming.security.principal

The (optional) user principal for connecting to the JNDI context.

org.quartz.dataSource.NAME.java.naming.security.credentials

The (optional) user credentials for connecting to the JNDI context.

Example of a Datasource referenced from an Application Server

org.quartz.dataSource.myOtherDS.jndiURL=jdbc/myDataSource
org.quartz.dataSource.myOtherDS.java.naming.factory.initial=com.evermind.server.rmi.RMIInitialContextFactory
org.quartz.dataSource.myOtherDS.java.naming.provider.url=ormi://localhost
org.quartz.dataSource.myOtherDS.java.naming.security.principal=admin
org.quartz.dataSource.myOtherDS.java.naming.security.credentials=123

Custom ConnectionProvider Implementations

Property Name	Required	Type	Default Value
org.quartz.dataSource.NAME.connectionProvider.class	yes	String (class name)	null

org.quartz.dataSource.NAME.connectionProvider.class

The class name of the ConnectionProvider to use. After instantiating the class, Quartz can automatically set configuration properties on the instance, bean-style.

Example of Using a Custom ConnectionProvider Implementation

org.quartz.dataSource.myCustomDS.connectionProvider.class = com.foo.FooConnectionProvider
org.quartz.dataSource.myCustomDS.someStringProperty = someValue
org.quartz.dataSource.myCustomDS.someIntProperty = 5
