20090198783 | METHOD OF REMOTE CONFIGURATION OF AUTOMATIC RESPONSE SETTINGS FOR A FIRST EMAIL ADDRESS USING AN EMAIL SENT FROM A SECOND EMAIL ADDRESS - A method of providing remote configuration of autoreply message settings includes providing for an autoreply message configuration rule to be defined in terms of one or more specified conditions and one or more specified actions configuring autoreply message settings for a first email address; receiving a first email message addressed to the first email address and sent from a second email address; examining the first email message for the one or more specified conditions; executing the one or more specified actions configuring autoreply message settings if the one or more specified conditions are met by the first email message; and generating an autoreply message in accordance with the autoreply message settings configured by executing the one or more specified actions in response to receiving a second email message addressed to the first email address if the one or more specified conditions are met by the first email message. | 08-06-2009 |
20090252047 | DETECTION OF AN UNRESPONSIVE APPLICATION IN A HIGH AVAILABILITY SYSTEM - A method, information processing system, and computer program storage product for determining if an application has become unresponsive. Network traffic at a receiver node is monitored. The receiver node is determined to have generated a window probe response indicating a predetermined window size. A threshold associated with the window size of the receiver node is set in response to the receiver node having generated the window probe response. The window size of the receiver is determined to have been at the predetermined size for at least one of a time period greater than the threshold and a count greater than the threshold. An application associated with the receiver node is classified as unresponsive in response to the window size of the receiver node having been the predetermined size for at least one of a timer period greater than the threshold and a count greater than the threshold. | 10-08-2009 |
20090254775 | METHOD FOR ENABLING FASTER RECOVERY OF CLIENT APPLICATIONS IN THE EVENT OF SERVER FAILURE - A system and method are provided for improving recovery times in fallover conditions in a multinode data processing system by sending notification of the failure of a server node, which is acting as server for a client application running on a client node, to the client application. In the present invention, this notification is provided by the fallover node acting as backup for the server node. When a client application receives no response from a server for a long time, it assumes that the server has failed and initiates reconnection. The present invention speeds-up the reconnect initiated by the client application by having system level software proactively notify the client application about the server failure. This results in faster recovery for client applications. | 10-08-2009 |
20110022882 | Dynamic Updating of Failover Policies for Increased Application Availability - Mechanisms are provided for performing a failover operation of an application from a faulty node of a high availability cluster to a selected target node. The mechanisms receive a notification of an imminent failure of the faulty node. The mechanisms further receive health information from nodes of a local failover scope of a failover policy associated with the faulty node. Moreover, the mechanisms dynamically modify the failover policy based on the health information from the nodes of the local failover scope and select a node from the modified failover policy as a target node for failover of an application running on the faulty node to the target node. Additionally, the mechanisms perform failover of the application to the target node based on the selection of the node from the modified failover policy. | 01-27-2011 |
20120144232 | Generation of Standby Images of Applications - Embodiments that generate checkpoint images of an application for use as warm standby are contemplated. The embodiments may monitor accesses of external references by threads. An external reference may comprise a connection or use of services of an entity that is external to the set of processes that constitute the application, to which a process of the application attempts to connect by means of a socket or inter-process communication (IPC). Various embodiments comprise two or more computing devices, such as two or more servers. One of the computing devices may generate a checkpoint image of an application at a suitable point in time during initialization, when the state of the application is not yet dependent on interactions with external references. The second computing device may preload checkpoint image for the application and activate the checkpoint images when needed, following the specific resource management rules of the distributed subsystem. | 06-07-2012 |

20090254649 | HIGH AVAILABILITY OF INTERNET PROTOCOL ADDRESSES WITHIN A CLUSTER - A method, information processing system, and computer program storage product manage network layer addresses in a cluster multi-processing environment. Network address assignment in a cluster multi-processing environment is monitored. A network address currently assigned to a first network interface is determined, in response to monitoring network address assignment, to have been assigned to a second network interface. The first network interface is triggered to send an update message to at least one computing node communicatively coupled to the first network interface triggering in response to determining that a network address currently assigned to a first network interface has been assigned to a second network interface. The update message informs the computing node to transmit data associated with the network address to the first network interface. | 10-08-2009 |

20110252272 | FALLOVER POLICY MANAGEMENT IN HIGH AVAILABILITY SYSTEMS - The method determines whether a particular node of a high availability cluster is functioning properly or is a failed node. The method dumps node process state information as a dump data for the failed or crashed node in a shared storage area of the high availability cluster. A high availability cluster manager identifies the dump data that corresponds to the failed node as the most recent dump data for that failed node. The high availability cluster manager interrogates the dump data using kernel debugger services to identify a process trace and thereby identify the crash-causing application for the failed node. The method determines if the dump data includes a process match for the failed node process. The high availability cluster manager may initiate a crash-causing application notification to administrators or other entities of the high availability cluster. The method provides relocation and restoration capability of applications from the failed node to a fallover node and returns those application resources to the user and other entities using the high availability cluster. | 10-13-2011 |

20140304495 | SYSTEM AND METHOD FOR EXPEDITING VIRTUAL I/O SERVER (VIOS) BOOT TIME IN A VIRTUAL COMPUTING ENVIRONMENT - An approach for management of boot time of a virtual machine is provided. In one aspect, a system boot time application identifies assigned resources of a virtual I/O server (VIOS) of a computing system. In addition, the system boot time application allocates additional resources from client logical partitions (LPARs) of the computing system to the assigned resources of VIOS during boot time of VIOS. The system boot time application further identifies cores of the computing system during the boot time of VIOS. The system boot time application also sets the cores in turbo core mode until boot time of VIOS is completed. In one aspect, the system boot time application reallocates the allocated additional resources from VIOS to the client LPARs once boot time of VIOS is completed. | 10-09-2014 |

20090040232 | METHOD TO RECORD BUS DATA IN A GRAPHICS SUBSYSTEM THAT USES DMA TRANSFERS - In a graphics based subsystem based on direct memory access transfer, a user queue library is used by the application program interface to send graphic command data to the graphics adapter. The user queue library transfers data stored within the user queue to the graphics adapter using direct memory access transfers. The user queue library determines whether the data should be saved. The application program interface calls a user queue routine from a user queue library. The user queue routine saves the control data to a trace file in memory. The user queue routine then transfers the graphics command data to the graphics adapter using a direct memory access transfer. | 02-12-2009 |
