System and method for providing dynamic transaction optimizations
A system and method for providing dynamic transaction optimizations, such as dynamic XA transaction optimizations. In accordance with an embodiment, the system enables monitoring of transactional behavior in an application during runtime, in order to provide a feedback loop. The application/transaction information in the feedback loop can be analyzed by a transaction manager to determine an indication as to whether a particular optimization, such as an isSameRM optimization, will provide a benefit or not. The optimization can then be applied accordingly. In accordance with various embodiments, such determination can be made transparently, so that its enablement is not detectable to, e.g., an end-application, or a system administrator, even though the distribution and type of XA calls may be detected through system monitoring. The feature can be used to improve the performance of transaction processing in a transaction-based system.

one or more transaction managers which receive the transaction requests from the client applications and provide connections to the resource managers to enable the resources to be updated; and
one or more dynamic optimizations which can be dynamically enabled or disabled by the transaction managers at runtime in response to application/transaction feedback information from the resource managers;
wherein the resource managers continuously provide the application/transaction feedback information to the transaction managers to determine whether a particular dynamic optimization will provide a benefit or not, and in which circumstances; and

4. The system of claim 1 , wherein the application/transaction feedback information is stored only in transient memory for use by the transaction manager for the duration of its uptime.
5. The system of claim 1 , wherein the application/transaction feedback information is persisted for use by the transaction manager after a reboot.
6. The system of claim 1 , further comprising one or more transaction processing monitors which coordinate the transaction requests between the client applications and the resources.
