| 20080288946 | States matrix for workload management simplification - A computer-implemented method, system and article of manufacture for managing workloads in a computer system, comprising monitoring system conditions and operating environment events that impact on the operation of the computer system, using an n-dimensional state matrix to identify at least one state resulting from the monitored system conditions and operating environment events, and initiating an action in response to the identified state. | 11-20-2008 |
| 20080306950 | Arrival rate throttles for workload management - A computer-implemented method, system and article of manufacture for managing workloads in a computer system, comprising monitoring system conditions and operating environment events that impact on the operation of the computer system, regulating execution of one or more queries based on the monitored system conditions and operating environment events using arrival rate throttles, and performing the queries to access data in a database for presentation and use to a user. | 12-11-2008 |
| 20090049024 | Dynamic query optimization between systems based on system conditions - A computer-implemented system, method and article of manufacture for managing a plurality of database systems in a domain, wherein each of the database systems are managed by one or more closed-loop system management (CLSM) regulators. A virtual regulator manages the domain, wherein the virtual regulator communicates with the CLSM regulators to monitor the database systems' system conditions and operating environment events within the domain and to provide for dynamic query optimization between the database systems within in the domain based on the system conditions and operating environment events. | 02-19-2009 |
| 20090132536 | Dynamic control and regulation of critical database resources using a virtual memory table interface - A computer-implemented apparatus, method, and article of manufacture provide the ability to manage a plurality of database systems. A domain contains the database systems, and a database in one of the systems has segmented global memory partitions. A virtual monitor partition provides logon access to the segmented global memory partitions in a form of a virtual database. Open application programming interfaces (API) enable logon access to the virtual monitor partition to access data in the virtual database. A multi-system regulator manages the domain and utilizes the open APIs to access data in the virtual data base. | 05-21-2009 |
| 20090327216 | Dynamic run-time optimization using automated system regulation for a parallel query optimizer - A computer-implemented apparatus, method, and article of manufacture for optimizing a database query. System conditions and operating environment events that occur during operation of the computer system are monitored. An n-dimensional optimizer matrix is used to identify at least one rule resulting from the monitored system conditions and operating environment events. An optimal query execution plan is selected from among a plurality of query execution plans generated for the query in response to the identified rule. | 12-31-2009 |
| 20090327242 | Parallel, in-line, query capture database for real-time logging, monitoring and opitmizer feedback - A computer-implemented method, apparatus and article of manufacture for optimizing a database query. A query execution plan is generated for the database query, which may be stored in an in-line query capture database. Execution of the query execution plan may be monitored in order to generate performance information, which also may be stored in the in-line query capture database. The data stored in in-line query capture database may be used during the initial generation of query execution plans, as well as for the re-optimization of a query execution plan, during the execution of the query execution plan. | 12-31-2009 |
| 20100153958 | SYSTEM, METHOD, AND COMPUTER-READABLE MEDIUM FOR APPLYING CONDITIONAL RESOURCE THROTTLES TO FACILITATE WORKLOAD MANAGEMENT IN A DATABASE SYSTEM - A system, method, and computer-readable medium that facilitate workload management in a computer system are provided. A workload's system resource consumption is adjusted against a target consumption level thereby facilitating maintenance of the consumption to the target consumption within an averaging interval by dynamically controlling workload concurrency levels. System resource consumption is compensated during periods of over or under-consumption by adjusting workload consumption to a larger averaging interval. Further, mechanisms for limiting, or banding, dynamic concurrency adjustments to disallow workload starvation or unconstrained usage at any time are provided. Disclosed mechanisms provide for category of work prioritization goals and subject-area resource division management goals, allow for unclaimed resources due to a lack of demand from one workload to be used by active workloads to yield full system utilization at all times, and provide for monitoring success in light of the potential relative effects of workload under-demand, and under/over-consumption management. | 06-17-2010 |
| 20100162251 | SYSTEM, METHOD, AND COMPUTER-READABLE MEDIUM FOR CLASSIFYING PROBLEM QUERIES TO REDUCE EXCEPTION PROCESSING - A system, method, and computer-readable medium that facilitate classification of database requests as problematic based on estimated processing characteristics of the request are provided. Estimated processing characteristics may include estimated skew including central processing unit skew and input/output operation skew, central processing unit duration per input/output operation, and estimated memory usage. The estimated processing characteristics are made on a request step basis. The request is classified as problematic responsive to determining one or more of the estimated characteristics of a request step exceed a corresponding threshold. In this manner, mechanisms for predicting bad query behavior are provided. Workload management of those requests may then be more successfully provided through workload throttles, filters, or even a more confident exception detection that correlates with the estimated bad behavior. | 06-24-2010 |
| 20110055168 | SYSTEM, METHOD, AND COMPUTER-READABLE MEDIUM TO FACILITATE APPLICATION OF ARRIVAL RATE QUALIFICATIONS TO MISSED THROUGHPUT SERVER LEVEL GOALS - A system, method, and computer-readable medium that provide mechanisms for tracking the number of queries received for processing for a workload to facilitate arrival rate qualifications to Throughput Service Level Goals are provided. A number of queries counter associated with a particular workload is incremented each time a query assigned to the particular workload is received thereby tracking the arrival rate of workload queries. When a system performance condition comprising a non-compliant system performance level with respect to a Throughput Service Level Goal is identified, the number of queries counter is compared with the Throughput Service Level Goal. If the arrival rate of queries for the workload is greater than the Throughput Service Level Goal of the workload, actions associated with non-compliance of the Throughput Service Level Goal may then be performed. If the number of queries counter is less than or equal to the Throughput Service Level Goal, the preliminary identification of the missed Service Level Goal as a system performance condition event is dismissed or otherwise ignored. | 03-03-2011 |
