OSDL Offers First Open Source
Database Test Tools
OSDL, a non-profit global consortium promoting Linux in the enterprise,
announced availability of OSDL-DBT, a suite of open source database workload
testing tools which are a fair use implementation of specific industry-
standard Transaction Processing Performance Council (TPC) benchmarks.
The engineering tools allow the testing of three key areas of application
performance -- Web, online transaction processing (OLTP) and decision support.
The database workload tests for the first time provide open source developers
with access to a set of performance tools similar to those used by proprietary
software developers for testing commercial computing environments. They join
OSDL's growing set of developer tools available online.
"Our mission at OSDL is to give open source developers the resources they
can't get elsewhere because they're proprietary or too expensive," said
Timothy Witham, OSDL lab director. "Tools like OSDL-DBT help build enterprise
class performance and availability into database applications on Linux."
"OSDL-DBT helps ISVs bring more enterprise applications to Linux," said
Bill
Claybrook, an industry analyst with the Aberdeen Group. "Licensing and cost
issues have prevented most companies and developers from conducting critical
benchmark and performance testing. Making these tests open source and
available over the Web will enable both kernel and application developers to
optimize their software for environments that closely simulate the demands of
data center computing."
OSDL-DBT workload testing tools are open source, fair-use implementations
of
Transaction Processing Performance Council (TPC) benchmarks and are published
using the Artistic License. These tools test the most important performance
characteristics in an application but, since they are not a complete
implementation of TPC-audited benchmarks, OSDL-supplied results may not be
used for commercial purposes.
OSDL-DBT-1 is based on the TPC-W, a transactional web benchmark simulating
the
activities of internet users using an online book store.
OSDL-DBT-2 is based on the TPC-C, an online transaction processing
benchmark,
simulating the activities of a wholesale supplier with geographically
distributed sales districts and associated warehouses.
OSDL-DBT-3 is based on the TPC-H, decision support benchmark consisting of
a
series of ad-hoc queries and concurrent data modifications.
The OSDL-DBT workload tests are database independent so long as the
software
meets certain technical requirements, including transaction management and an
ODBC driver. Currently they are implemented with SAP DB.
The OSDL-DBT workloads are available through OSDL's Scalable Test Platform
(STP), an automated kernel testing platform. STP permits easy evaluation of
performance and stability of the Linux kernel by allowing simple, web-based
customization of stock kernels and running tests against them. The entire
suite runs at OSDL's lab with results available on the Web. These
implementations can also be used for custom tests by developers upon
request.
