A system and method for allowing transaction callback processing to be synchronized or to take effect prior to completion of a transaction or message. Additional objects that will take part in the transaction can be registered on any server during the transaction's active phase. After the commit function is called, each synchronization object is called during the transaction preprepare processing. A synchronization object can register another object, call a server not previously involved in the transaction, or involve a new resource in the transaction. The effect is to provide a circular pattern of request passing that allows additional resources to be added into the loop prior to commit.

System and method for prepreparing a transaction process involving a chain of servers in a circular flow

A system for deploying applications that comprises a data storage component capable of containing at least one application to be deployed and an administration component capable of deploying the application from the data storage component to a managed component. The managed component is capable of receiving the application from the data storage component preparing the received application for deployment on the managed component; and activating the deployment once the managed component is prepared. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.

Systems and methods for application deployment

A transaction service that allows lightweight clients to perform a delegated commit at a server. This process allows lightweight clients to begin and terminate transactions, while the actual responsibility for transaction commit processing is delegated to a commit server and transaction manager running on the machine hosting the server. Client applications do not require a local transaction server. The commit server can be selected from the plurality of servers accessible to the client, and is responsible for committing the transaction to other (participating) servers taking part in the transaction.

System and method for transaction processing with delegated commit feature

The invention provides a mechanism for allowing a transaction callback processing to be synchronized or to take effect prior to completion of a transaction or message. Additional Synchronization objects that will take part in the transaction can be registered on any server during the transaction's active phase. After the commit function is called, each Synchronization object is called during the transaction preprepare processing. A Synchronization object can register another Synchronized object, call a server not previously involved in the transaction, or involve a new XA resource in the transaction. The effect is to provide a circular pattern of request passing that allows additional resources to be added into the loop prior to commit.

Applications can be deployed concurrently across a network cluster by utilizing a phased approach to deployment. A preparation operation is invoked each node on which an application is to be deployed. The preparation operation can utilize two phases, in which the deployment descriptors for an application are analyzed and in which each node is initialized for deployment. For each node that is successfully initialized, an activation phase is started in which the node is informed that it should prepare for requests on the application. The deployed application is then started on each successful node. For each node on which the preparation operation was unsuccessful, the deployment can be rolled back or attempted again.

The invention provides a mechanism for use with a transaction processing system that allows a transaction to include a number of associated transaction properties. Transaction properties in turn allow named objects to be associated with a transaction. Transaction properties are available wherever the transaction is active. They can be used as a form of attachment or out-of-band communication mechanism as a transaction flows to various servers in a distributed system, or between different software modules within a single system.

System and method for transaction processing with transaction property feature

In embodiments, a multi-phase approach can be used to deploy an application across a network or server cluster. A master deployer on an administration server is contacted, such as by a deployment tool, indicating that an application is to be deployed. The master contacts a slave deployer on each managed server that is to deploy the application, indicating that the slave should prepare for deployment. The slave can pull the application from an application source into a staging area for each managed server. In the staging area, each managed server explodes the application from an application archive file, if necessary, and attempts to load the application. The managed servers notify the master of the success of the load, and if all loads are successful each application can be moved to a production directory and activated.

Systems and methods for application management and deployment

The invention provides a transaction service that allows lightweight clients to perform a delegated commit at a server. This process allows lightweight clients to begin and terminate transactions, while the actual responsibility for transaction commit processing is delegated to a commit server and transaction manager running on the machine hosting the server. Client applications do not require a local transaction server. The commit server can be selected from the plurality of servers accessible to the client, and is responsible for committing the transaction to other (participating) servers taking part in the transaction.
