| 20110047537 | Updating client node of computing system - During execution of an existing scheduling computer program on a client node, an update computer program and a self-describing automatic installation package are downloaded to the client node from a logical depot node implemented on an existing management server. Therefore, advantageously, no physical depot node or other additional computing device is needed for the client node to update itself. Execution of the update computer program is spawned on the client node from the existing scheduling computer program. As such, the update computer program inherits root access to the client node and security credentials to the management server from the scheduling computer program—advantageously, then, a user does not have to perform any laborious configuration of the client node in order to update the node. The client node ultimately updates itself using the self-describing automatic installation package, which includes all the information needed for the client node to update itself. | 02-24-2011 |
| 20110106760 | SYNCHRONIZING DATABASE AND NON-DATABASE RESOURCES WITHOUT A COMMIT COORDINATOR - A system to synchronize a database and a non-database resource includes an application to transmit a request to a service provider to perform an action. The service provider receives the request and performs the action, the action not being under commit coordination. The service provider further inserts an entry into an action-reversal table to reverse the action and makes the insertion permanent. The service provider, on behalf of the application, then deletes the entry from the action-reversal table. The application may then be configured to perform one of the following: (1) make the delete permanent by performing a COMMIT; and (2) roll back the delete by performing a ROLLBACK. At a later time, the service provider may reverse the action in the event the entry remains in the action-reversal table. Corresponding methods and articles of manufacture (i.e., computer-readable media) are also disclosed herein. | 05-05-2011 |
