Chapter 32 Improving VOB Host Performance

This chapter presents techniques for improving the performance of Rational ClearCase on VOB hosts.

Your organization's VOBs constitute a central data repository. Good VOB host performance ensures that this centralized resource does not become a bottleneck.

The work of a VOB host involves both read and write access to the VOB database as well as periods of significant computation. VOB access patterns can greatly influence the number of concurrent users that a VOB host can support at a given level of performance. For example, many more users can read from a VOB directory at a level of good performance than can write to the same directory. For information about the characteristics of a good a VOB host, see Chapter 9, VOB Server Configuration Guidelines.
