| A TransactionManager can be declared via xml in the |
| `<tomee-home>/conf/tomee.xml` file or in a `WEB-INF/resources.xml` file |
| using a declaration like the following. All properties in the element |
| body are optional. |
| |
| [source,xml] |
| ---- |
| <TransactionManager id="myTransactionManager" type="TransactionManager"> |
| adler32Checksum = true |
| bufferSizeKb = 32 |
| checksumEnabled = true |
| defaultTransactionTimeout = 10 minutes |
| flushSleepTime = 50 Milliseconds |
| logFileDir = txlog |
| logFileExt = log |
| logFileName = howl |
| maxBlocksPerFile = -1 |
| maxBuffers = 0 |
| maxLogFiles = 2 |
| minBuffers = 4 |
| threadsWaitingForceThreshold = -1 |
| txRecovery = false |
| </TransactionManager> |
| ---- |
| |
| Alternatively, a TransactionManager can be declared via properties in |
| the `<tomee-home>/conf/system.properties` file or via Java |
| VirtualMachine `-D` properties. The properties can also be used when |
| embedding TomEE via the `javax.ejb.embeddable.EJBContainer` API or |
| `InitialContext` |
| |
| [source,properties] |
| ---- |
| myTransactionManager = new://TransactionManager?type=TransactionManager |
| myTransactionManager.adler32Checksum = true |
| myTransactionManager.bufferSizeKb = 32 |
| myTransactionManager.checksumEnabled = true |
| myTransactionManager.defaultTransactionTimeout = 10 minutes |
| myTransactionManager.flushSleepTime = 50 Milliseconds |
| myTransactionManager.logFileDir = txlog |
| myTransactionManager.logFileExt = log |
| myTransactionManager.logFileName = howl |
| myTransactionManager.maxBlocksPerFile = -1 |
| myTransactionManager.maxBuffers = 0 |
| myTransactionManager.maxLogFiles = 2 |
| myTransactionManager.minBuffers = 4 |
| myTransactionManager.threadsWaitingForceThreshold = -1 |
| myTransactionManager.txRecovery = false |
| ---- |
| |
| Properties and xml can be mixed. Properties will override the xml |
| allowing for easy configuration change without the need for $\{} style |
| variable substitution. Properties are not case sensitive. If a property |
| is specified that is not supported by the declared TransactionManager a |
| warning will be logged. If a TransactionManager is needed by the |
| application and one is not declared, TomEE will create one dynamically |
| using default settings. Multiple TransactionManager declarations are |
| allowed. # Supported Properties |
