• Working with the AS/400 database
A number of enhancements have been added to Operations Navigator for database
programmers and administrators:
– Visual Explain is a new function that provides a pictorial view of query optimization,
and allows users to easily get information for improving query performance.
– A new function has been added to display currently executing SQL statements for a
job.
– Tables, views, and indexes have been enhanced with a description window that
displays and, in some cases, allows changing the attributes of these important
objects.
• Integrated Netfinity Server Administration
The Integrated Netfinity Server can be managed through the Operations Navigator. These
Windows servers can be stopped, started, changed, and listed to view their status, and
their attributes can be managed.
The Client Access Express for Windows client (V4R5M0), which includes the above
Operations Navigator enhancements, is shipped with OS/400 V4R5 and can be
downloaded from the AS/400 NetServer to PC Windows desktops. Client Access Express
runs on Microsoft Windows 95, 98, NT 4.0, and Windows 2000 operating systems and
can be used to connect to AS/400 systems running OS/400 V4R2 or later. See the
Licensed Program Offering (LPO) announcement for other enhancements which are
available in the Express client.
Management Central
A suite of system management functions known as Management Central has been integrated
into Operations Navigator. These functions include:
• Collection Services
This tool for collecting and managing performance data replaces the traditional
performance monitor function with a low-overhead, automated, and on-going data
collector. Data is captured with reduced system impact. Processing occurs only if and
when needed. Additionally, Collection Services lets you control what data is collected and
how that data is managed.
Each type of data supported by collection services can be controlled individually without
data loss or affecting the collection of other data.
A compatible performance monitor database is created based on the data in the
management collection object. However, you can defer the creation of the database until
a later time.
