The XPU database tool is used to monitor the consistency of the volumes in a database instance and to update the statistics for the SQL Optimizer.
XPU only analyzes the state of the database instance and does not reorganize it.
We recommend that you only use XPU in production systems if you have a sound knowledge of databases.
XPU is a command line tool and can be used on all operating systems supported by the database system.
XPU is part of the MaxDB software, which you can download from the MaxDB web site (see Download and Installation Profiles).
For further information about the database system, see the documentation Concepts of the Database System and the Glossary.
