Configuring Dynamo to use WebSphere’s transaction manager is similar to configuring the data sources; you replace Dynamo’s TransactionManager component with a pointer to WebSphere’s transaction manager. To do this, you create a TransactionManager.properties file that contains these lines:
$class=atg.dtm.StaticTransactionManagerWrapper
useManagerMethods=true
Put this file in the <ATG2007.3dir>/home/localconfig/atg/dynamo/transaction directory and in the corresponding directory of each Dynamo server. For example, if you have created a server named server1, copy the file into the directory <ATG2007.3dir>/home/servers/server1/localconfig/atg/dynamo/transaction.
In addition, add the following line to the GLOBAL.properties file in the <ATG2007.3dir>/home/localconfig directory and in the corresponding directory for each server:
localTransactionModeInitialization=false
