HP Neoview Release 2.3 Software - Manual (Page 9)

About This Document
This document describes the views supported by the Neoview Manageability Repository, a
Neoview SQL database and set of programs that collect and store statistics and other information
about queries, query sessions, tables, disks, processing nodes, and (optionally) selected processes
involved in query execution on a Neoview platform.
Supported Release Version Updates (RVUs)
This manual supports N02.03 and subsequent N-series RVUs until otherwise indicated in a
replacement publication.
Intended Audience
This document is intended for system managers, database administrators, and other users
interested in evaluating query performance and resource utilization on a Neoview platform.
Familiarity with Neoview SQL is a prerequisite.
New and Changed Information in This Edition
The R2.3 edition of this manual includes the following new and changed information:
• Description of Query Runtime Statistics as a standard feature, and enhancements to the
view that provides access to the data.
• Description of the Disk entity and views that provide metric information for Disks.
• Updates to reflect enhancements in the gathering of Table statistics.
• Notes on support for alternative (Japan Shift-JIS and Unicode) character sets, where
applicable.
• Naming changes to reflect the catalog and schema within which Repository views are defined.
The new catalog name is NEO; the new schema name is HP_METRICS.
• Naming changes to reflect the fact that the product formerly called Neoview Script is now
called Neoview Command Interface.
• Deletion of text and descriptions of prepackaged queries, which are no longer part of the
Repository product. (The Neoview Reports product includes prepackaged queries. For more
information, see the Neoview Reports Online Help.)
• Removal of references to the table census utility, which is superseded by new functions in
the Table data collector.
The R2.2 edition of this manual included the following new and changed information:
• Descriptions of new Repository views that provide access to Query Runtime Statistics and
Table metrics.
• Field naming changes in most Repository views, to reflect standard Neoview terminology.
For example, the term “node” has been replaced by “segment” in the views themselves, and
thus in the documentation, wherever applicable.
• Removal of deprecated Repository views (which had names starting with ACCESS). These
views are still present in the software but no longer described in the manual.
• New ANSI SQL Date and Time columns, which permit ANSI SQL standard date and time
computations.
• Enhancements to Repository status queries to incorporate new features, such as support for
Table metrics.
• New prepackaged queries, and changes in existing queries, to reflect new Repository features
and field naming changes.
