A data processing system service includes enabling the system to perform diagnostic processing in response to a system failure and enabling the system to perform corrective action during the automated diagnostic processing to attempt to resolve the system failure. The service further includes configuring the system to generate a trouble ticket containing information characterizing the system failure and any attempted corrective action regardless of whether the corrective action was successful in resolving the system failure. The system may be further enabled to forward the trouble ticket to an external database for analysis and to access the external database to determine whether the detected failure has been encountered previously. The system may be partitioned into two partitions including a diagnostic partition. The system boots to the diagnostic partition following a failure or in response to a request from a user.

A means for guaranteeing the proper behavior as specified by the JMS semantics of clustered message server when the individual computer that comprise the cluster are separated by a network partition. A clustered message server is responsible for the reliable transportation of messages between different distributed computer applications. It employs multiple computers to perform a function that otherwise appears to be performed by a monolithic server running on one computer, but with more capacity and reliability than can be provided by one computer. If a computer in the cluster fails, another computer should automatically assume the role of the failed computer. However, it is not possible for the other machines in the cluster to detect the difference between the failure of one or more computers in the cluster, and the failure of data network connecting those computers. In ordinary clusters, different actions would be required in these two cases, but since they are impossible to distinguish, computer failure is always assumed and network failure is ignored and the consequence non-deterministic. The invention described here provides a means of responding to failures that yields correct behavior as specified by the JMS semantics whether the failure is due to computer failure or network failure.

Methods and arrangements are provided that substantially reduce the requisite amount of data required to conduct postmortem analysis following a computer failure. The methods and arrangements can be advantageously configured to allow for rapid online user support for a variety of users, computing devices, operating systems, applications, and the like. One method includes determining when to generate a dump file, and generating a dump file by gathering thread, callstack and thread context information for the running thread, process identifying information associated with the running thread, and information identifying the reason for generating the dump file. The resulting dump file is then stored to a storage medium and accessed during subsequent analysis. The dump file can be a kernel minidump file that is associated with an operating system program failure, in which case the running thread is the single thread that was running when the failure occurred. The kernel minidump file would include the kernel callstack and the process identifying information that would identify the process that initiated the single thread. The method is further applicable to non-operating system programs, wherein a user minidump file is generated by also gathering callstack information for all running threads, thread context information for all running threads, and a listing of all loaded modules for the faulting non-operating system program.

A computer condition detection system for detecting conditions of computer components to predict a failure. Conditions on computer components may be detected by a health computer coupled to a main computer (e.g., a computer blade). The health computer may be coupled to sensors on various computer components for detecting conditions such as temperature, airflow velocity, voltage, and current. The health computer may be coupled to an independent health network and may be powered by a separate power supply than the main computer power supply to detect problems even if the main computer fails. The main computer may also be coupled to the sensors to detect conditions on the main computer's components. If a condition is detected that meets a predetermined criterion, corrective or preparative actions may be taken. For example, data on the main computer may be backed up in anticipation of a main computer failure.

A data processing system service and method includes enabling the system to perform diagnostic processing in response to identified system problems and enabling the system to generate a trouble ticket containing machine and problem-specific information. The service and method further include forwarding the trouble ticket to an external server which responds with a unique identifier tied logically to the trouble ticket. The service and method of the present invention requires that requested services such as a help desk call or the return of the system for repair or replacement be obtained only upon presentation of the unique identifier. The system may be partitioned into at least two partitions including a diagnostic partition wherein the diagnostic processing is performed. The system boots to the diagnostic partition upon recognition of a system problem, either automatically or by a user.

The data processing system controls, from the database management system on a host computer, the storage device subsystem which stores log data supplied from the database management system; allocates on a disk cache in the storage device subsystem in advance a log-dedicated buffer area of a size equal to that of the log data output between checkpoints; writes log data into the buffer area; and, in the event of a host computer failure, reads out the log data from the disk cache without making access to a disk device. Since the log information required for the recovery of the data processing device is cached on the storage device side, the time it takes to read the necessary log information can be shortened, which in turn reduces the system recovery time.

An additional communications link between two mass-storage devices containing LUNs of a mirrored-LUN pair, as well as incorporation of a fail-safe mass-storage-device-implemented retry protocol to facilitate non-drastic recovery from communications link failures within the controllers of the two mass-storage devices, prevents build-up of WRITE requests in cache and subsequent data loss due to multiple communications-link and host computer failures. The combination of the additional link and the retry protocol together ameliorates a deficiency in current LUN-mirroring implementations that often leads to data loss and inconsistent and unrecoverable databases.
