August 2011 TPCTC'11: Proceedings of the Third TPC Technology conference on Topics in Performance Evaluation, Measurement and Characterization
Publisher: Springer-Verlag
Bibliometrics:
Citation Count: 3

Advances in hardware architecture have begun to enable database vendors to process analytical queries directly on operational database systems without impeding the performance of mission-critical transaction processing too much. In order to evaluate such systems, we recently devised the mixed workload CH-benCHmark, which combines transactional load based on TPC-C order ...
Keywords: mixed workload, real-time business intelligence

While standardized and widely used benchmarks address either operational or real-time Business Intelligence (BI) workloads, the lack of a hybrid benchmark led us to the definition of a new, complex, mixed workload benchmark, called mixed workload CH-benCHmark. This benchmark bridges the gap between the established single-workload suites of TPC-C for ...

Publisher: ACM

Citation Count: 1

Ideally, a data warehouse would be able to run multiple types of queries concurrently, meeting different performance objectives for each type. However, due to the difficulty of managing mixed workloads, most commercial systems segregate distinct workload components by using strict resource partitioning and/or time multiplexing. This approach avoids unexpected resource ...

March 2010 DNIS'10: Proceedings of the 6th international conference on Databases in Networked Information Systems
Publisher: Springer-Verlag
Bibliometrics:
Citation Count: 3

As data warehousing technology gains a ubiquitous presence in business today, companies are becoming increasingly reliant upon the information contained in their data warehouses to inform their operational decisions. This information, known as business intelligence (BI), traditionally has taken the form of nightly or monthly reports and batched analytical queries ...

Full text available: PDFPDF
Workload management for operational business intelligence (BI) databases is difficult. Queries vary widely in length and objectives. Resource contention is difficult to predict and to control as dynamically-arriving, long, analyst queries compete for resources with ongoing online-transaction processing (OLTP) queries and batch report queries. Currently, administrators struggle to choose workload ...

Business Intelligence query workloads that run against very large data warehouses contain queries whose execution times range, sometimes unpredictably, from seconds to hours. The presence of even a handful of long-running queries can significantly slow down a workload consisting of thousands of queries, creating havoc for queries that require a ...

We explore how to manage database workloads that contain a mixture of OLTP-like queries that run for milliseconds as well as business intelligence queries and maintenance tasks that last for hours. As data warehouses grow in size to petabytes and complex analytic queries play a greater role in day-to-day business ...

Full text available: PDFPDF
In the past, enterprise resource planning systems were designed as monolithic software systems running on centralized mainframes. Today, these systems are (re-)designed as a repository of enterprise services that are distributed throughout the available computing infrastructure. These service oriented architectures (SOAs) require advanced automatic and adaptive management concepts in order ...

Full text available: PDFPDF
Workload management for business intelligence (BI) queries poses different challenges than those addressed in the online transaction processing (OLTP) context. The fundamental problem is that the execution times of BI queries can range from milliseconds to hours, and it is difficult to estimate these times accurately. Key challenges raised by ...

December 2006 ICSOC'06: Proceedings of the 4th international conference on Service-Oriented Computing
Publisher: Springer-Verlag
Bibliometrics:
Citation Count: 6

In today's enterprise service oriented software architectures, database systems are a crucial component for the quality of service (QoS) management between customers and service providers. The database workload consists of requests stemming from many different service classes, each of which has a dedicated service level agreement (SLA). We present an ...

Future database application systems will be designed as Service Oriented Architectures (SOAs) like SAP's NetWeaver instead of monolithic software systems such as SAP's R/3. The decomposition in finer-grained services allows the usage of hardware clusters and a flexible serviceto- server allocation but also increases the complexity of administration. Thus, new ...
