摘要： A hardware/software system for analyzing memory dumps. The system collects data structures in a memory dump into logical tables, one logical table per selected type of data structure. The logical tables are generated by use of extraction logic for extracting data in data structures in the memory dump. The extraction logic is used in conjunction with a template library that contains data structure definitions for various types of data structures. The extraction logic, together with the template library, make possible populating logical tables with the contents of data structures found in the memory dump. Each row in a logical table is dedicated to one data structure of the selected type. Collecting data structures into logical tables makes available the power of a standard database management system for operating on the logical tables to determine the cause of a crash of a hardware/software system for which the memory dump was taken.

摘要： Processing batch database workload while avoiding overload. A method for efficiently processing a database workload in a computer system comprises receiving the workload, which comprises a batch of queries directed toward the database. Each query within the batch of queries is assigned a priority. Resources of the computer system are assigned in accordance with the priority. The batch of queries is executed in unison within the computer system in accordance with the priority of each query thereby resolving a conflict within the batch of queries for the resources of the computer system, hence efficiently processing the database workload and avoiding overload of the computer system.

摘要： Methods, computer-readable storage media and computer systems are provided for transforming a directed acyclic graph (“DAG”) query plan into a linear plan. A DAG query plan may include a first operator and a second operator that are scheduled to be executed in parallel. The DAG query plan may be modified so that the first and second operators are executed in series as an upstream operator and a downstream operator. A data unit output from the upstream operator may be marked to indicate that the data unit has been processed by the upstream operator. The data unit received as input at the downstream operator may be inspected to determine whether the data unit has been marked. Once in linear form, the query plan may be optimized to conserve computing resources.
