DTM DB Stress is a utility for stress testing the server parts of information systems and
applications, as well as DBMSs and servers themselves. This tool allows you to create and
configure a continuous set of requests to the server of the OLAP (query execution) and OLTP
(adding, modifying and deleting data in the database) types. At the same time, the user can
flexibly change both the number and the priority of this or that type of requests to a database or
an application.
The program is useful for any information system developer or any QA department employee who
wants to make sure the product under development can work with a large number of simultaneous
connections and concurring queries and transactions. Database administrators can use this
utility to evaluate the current performance of servers and to make plans about increasing processing power.
A test package consists of a set of tasks. Each task is an SQL statement that will be
executed in a loop in the process of testing. Each task can be run as several copies running
simultaneously in separate threads. Tasks have different properties and priority.
There are several methods to finish a package:
- Manual, when the user himself has to click the Stop button
- According to the properties of each task - each copy of each task is executed as many times
as specified in its properties
- By time - all tasks will be running at least for the number of seconds specified by the user
- By the overall number of executed iterations. A package is finished if the overall number of
iterations for all copies (threads) of all tasks exceeds the specified value
- By the number of times each task is executed. A package is finished when each copy (thread) of each
task is executed the specified number of times
- By the number of times each thread is executed. A package is finished when thread copy of each
task is executed at least the specified number of times
In the last three cases those iterations that are already in process are not interrupted, but executed
to an end, that is why the actual number of executed iterations may exceed the specified value
or time a little.
DTM DB Stress is a true Win32 application, known to be compatible with the following operating systems:
Windows 98 and ME, Windows 2000 family, Windows XP (Home and Professional), Windows 2003 Server family and Windows Vista.
To be able to work with Windows 95 and Windows NT 4.0, you will have to download
an additional library set from our site.
