Configuration Properties

Table 3.124. 

Name Description Required Internal Name
JNDI Name The global JNDI name to bind the connection factory under. yes jndi-name
RAR Name The name of the RAR file that contains the definition for the resource we want to provide. For nested RAR files, the name would look like myapplication.ear#my.rar. yes rar-name
Connection Definition The connection factory interface class. It should match the connectionfactory-interface in the ra.xml file. yes connection-definition
Minimum Pool Size The minimum number of connections the pool should hold. The default is 0. no min-pool-size
Maximum Pool Size The maximum number of connections the pool should hold. The default is 10. no max-pool-size
XA Transaction Whether on not to use XA transactions. The default is No. no xa-transaction
Allocation Retry The number of times that allocating a connection should be tried before throwing an exception. The default is 0. no allocation-retry
Allocation Retry Wait Millis The time in milliseconds to wait between retrying to allocate a connection. The default is 5000 (5 seconds). no allocation-retry-wait-millis
Background Validation Specify if connections should be validated on a background thread versus being validated prior to use. Background validation is meant to reduce the overall load on the RDBMS system when validating a connection. The default is No. no background-validation
Background Validation Millis The interval, in milliseconds, at which the ConnectionValidator will run. Set to 0 to disable background validation. The default is 0. no background-validation-millis
Blocking Timeout in Milliseconds Indicates the maximum time in milliseconds to block while waiting for a connection before throwing an exception. Note that this blocks only while waiting for a permit for a connection, and will never throw an exception if creating a new connection takes an inordinately long time. The default is 30000 (30 seconds). no blocking-timeout-millis
Idle Timeout The maximum time, in minutes, a connection may be idle before being closed. The default is 30. no idle-timeout-minutes
Is Same RM Override Value If set, unconditionally sets the boolean return value of javax.transaction.xa.XAResource.isSameRM(XAResource). no isSameRM-override-value
Jmx Invoker Name The ObjectName of the JMX Invoker MBean associated with this datasource. no jmx-invoker-name
Metadata Metadata properties. no metadata
No Tx Separate Pools If true, the datasource cannot reuse a connection outside a transaction once enlisted in a global transaction and vice-versa. The default is Yes. no no-tx-separate-pools
Prefill Whether to attempt to prefill the connection pool to the minimum number of connections. NOTE: Only supporting pools (OnePool) support this feature. A warning can be found in the logs if the pool does not support this. The default is No. no prefill
Security Settings Security settings for connections in the pool. no security-domain
Statistics Formatter The fully qualified class name of the class to use for formatting managed connection pool statistics for this datasource. The class must implement the org.jboss.resource.statistic.formatter.StatisticsFormatter. interface. The default is "org.jboss.resource.statistic.pool.JBossDefaultSubPoolStatisticFormatter". no statistics-formatter
Type Mapping The name of the corresponding type-mapping in conf/standardjbosscmp-jdbc.xml. The type mappings provided by default: DB2, InformixDB, MaxDB, mySQL, Oracle9i, PointBase, InterBase, Mimer SQL, McKoi, SapDB, DB2/400, SOLID, Hypersonic SQL, FirstSQL/J, MS SQLSERVER2000, MS SQLSERVER, Cloudscape, Derby, Firebird, PostgreSQL 8.0, PostgreSQL, Sybase, Ingres. Note, there may be custom type mappings defined in addition to these predefined mappings. no type-mapping
Use Java Context Indicates whether the JNDI name should be bound under the "java" context, which causes the DataSource to only be accessible from within the JBossAS VM. The default is Yes. no use-java-context
Use Strict Min Whether idle connections below the min-pool-size should be closed. The default is No. no use-strict-min
Validate On Match The validate-on-match element indicates whether or not connection level validation should be done when a connection factory attempts to match a managed connection for a given set. This is typically exclusive to the use of background validation. The default is Yes. no validate-on-match
Config Property Properties to supply to the ManagedConnectionFactory (MCF) MBean service configuration. no config-property
Interleaving If true, enable transaction interleaving if the DB vendor supports it (most do not). Can only be set to true if XA transactions are enabled. This property supersedes the "track-connection-by-tx" property from earlier versions of JBoss AS. The default is false. no interleaving
XA Resource Timeout The maximum time, in minutes, an XA Resource can be idle before it is removed. 0 means no timeout. The default is 0. no xa-resource-timeout

Note

You must use the internal name to reference Configuration Properties in Dynamic Group Definition expressions.

Operations

Table 3.125. Metrics

Name Description
Flush Flush the connections in the pool
List Formatted Sub Pool Statistics Obtain a formatted sub pool statistics report
List Statistics Obtain a statistics report
Test Connection Test if a connection can be obtained - returns true if a connection was obtained, or false if not; NOTE: this operation will always return a status of Successful - the results of the operation must be inspected to see whether or not a connection was obtained
