Improving VOB host performance

Nearly all DevOps Code ClearCase® operations involve access to data in a VOB. Good VOB host performance ensures that VOB access does not become a bottleneck.

The work of a VOB host involves both read and write access to the VOB database in addition to 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 than can write to it with the same level of performance. For information about the characteristics of a good VOB host, see VOB host configuration guidelines.
