Timothy Valihora draws on nearly two decades of experience in information technology to provide management consulting services to such notable firms as Southern California Edison, Hilton Grand Vacations, and AMC Theatres. Certified in IBM’s InfoSphere Information Server (IIS), Timothy Valihora is well versed in the technical aspects of data management, including massively parallel processing (MPP) computing.
Also known as “shared nothing” or “loosely coupled” systems, MPP systems consist of several separate central processing units (CPUs) working simultaneously to execute one program. These systems are often used for applications that allow users to search several databases at once, such as decision support systems and data warehouse applications.
MPP systems are similar to symmetric multiprocessing (SMP) systems in that both involve several processors running one application; however, SMP systems share one common operating system and memory.
Over the years, Tim Valihora has conducted over 125 successful installs of IBM Information Server across a wide array of operating systems (Linux, UNIX, Windows) + many patches, fixpacks and upgrades etc. Many of these installations involved complex server topologies and high availability hardware architecture (including active/active Websphere Application Server etc.)
In recent years Mr. Valihora has specialized in supporting and implementing “Grid” architecture in terms of DataStage/QualityStage (i.e. the Grid Toolkit for DataStage along with resource managers such as the SUN Grid Engine, IBM Platform LSF etc.) – and also has worked extensively with Information Analyzer, Business Glossary, FastTrack and Information Services Director.
Tim Valihora is one of the top DataStage job performance tuners/Technical architects in North America.
Mr. Valihora has developed over 6000 DataStage/QualityStage jobs – which are currently in production environments – across various client sites – in North America.
Along with specializing in Grid implementations of IIS – Mr. Valihora has focused increasingly on technical architecture and performance tuning in the more recent years of his 20 year career in Information Technology.
