Configuring JobStoreCMT

The JobStoreCMT provides an alternate JobStore that can work with a relational database. You can choose the JobStoreCMT by selecting it with the org.quartz.jobStore.class property:

org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreCMT

When using the JobStoreCMT, a few additional properties can be set. These are shown in Table A.5.

Table A.5. The Properties for Configuring the Quartz JobStoreCMT

Name

Required

Type

Default Value

org.quartz.jobStore.nonManagedTXDataSource

Yes

String

null

org.quartz.jobStore.dontSetNonManagedTX-ConnectionAutoCommitFalse

No

Boolean

false

org.quartz.jobStore.txIsolationLevelReadCommitted

No

Boolean

false

 

org.quartz.jobStore.nonManagedTXDataSource

JobStoreCMT requires a (second) datasource that contains connections that will not be part of container-managed transactions. The value of this property must be the name of one of the datasources defined in the configuration properties file. This datasource must contain non-CMT connectionsin other words, connections for which it is legal for Quartz to directly call commit() and rollback() on.

org.quartz.jobStore.dontSetNonManagedTXConnectionAutoCommitFalse

This is the same as org.quartz.jobStore.dontSetAutoCommitFalse, except that it applies to the nonManagedTXDataSource.

org.quartz.jobStore.txIsolationLevelReadCommitted

When set to true, this property tells Quartz to call setTransactionIsolation(Connection.TRANSACTION_READ_UNCOMMITTED) on the non-managed JDBC connections. This can be helpful to prevent lock timeouts with some databases (such as DB2) under high load and long-lasting transactions.
