Downloadable files


The Domino Configuration Tuner (DCT) provides easy-to-use self-service configuration analysis for more robust installations and better performance of Domino servers.

Download Description

A single IBM Lotus Domino server includes thousands of configuration options. The Domino Configuration Tuner (DCT) provides best practice analysis as well as worst practice disclosure. DCT helps reduce total cost of ownership by assisting in the identification of existing configuration problems.

DCT evaluates server settings according to a growing catalog of best practices. All servers in a single domain can be evaluated together. DCT generates reports that explain the issues that are uncovered, suggest mitigations, and provides references to supporting publications. DCT also provides Domino support staff with a base-line assessment when initiating customer engagements.

This first revision of DCT looks at settings in Server documents, the NOTES.INI file, and database properties. Configuration settings are flagged when their values are known to cause problems based on prior customer experience. Out-of-range and unexpected values are reported so that undefined behavior can be prevented. Suggested adjustments help administrators achieve known server performance improvements.

Domino Configuration Tuner is available to any customer free of charge. It works with Lotus Domino server 7.0 and later, and runs on the Lotus Notes client, standard or basic, version 8 and later. There are no required changes to a customer domain configuration in order to take advantage of DCT evaluation.
