Figure 50 System Reporter Version Report

This query returns a 3x3 table with the column headers Category, Major, and Minor. The two rows

after the header contain major and minor numbers for Product and ReportData.

The Product version numbers are informational only and are the numbers assigned to the product

when it is released. The Product version number is not necessarily related to the ReportData version.

The Product version of the server will be the same as is displayed in the upper frame of the Web

client.

The ReportData version numbers correspond to the format of the data as provided by the server.

These numbers will change according to the following rules:

• Bug fixes do not cause a change in version number. If data in a table is being incorrectly

reported, fixing the server to report it correctly does not change the version.

• Adding one or more new columns to a table without changing any of the existing columns

causes the minor number to be incremented.

• Removing a column causes the major number to be incremented.

• Changing the meaning of a column causes the major number to be incremented.

Clients can accept lower version numbers if the client has been coded to work with previous

versions. Clients can accept newer minor numbers when the major number is the same since the

data format is compatible, but may wish to warn the user that not all features of the server's data

will be represented. The client should not attempt to use data from a server with a newer major

number. The simplest approach is for the client to reject a server unless the major and minor number

of the server's data format is the same as the data format specification used to code the client.

The definitions of queries and the data they return given below are version 4.1. A client coded to

these definitions would compare major number 4 and minor number 1 against the server's Report

Data major and minor numbers.

About Reports and Options

There are five categories of reports that you can generate using System Reporter:

• summary reports (see “Summary Report” (page 154))

• space reports (see “Space Reports” (page 155))

• performance reports (see “Performance Reports” (page 157))

• adaptive optimization reports (see “Adaptive Optimization Reports” (page 162))

• objects present reports (see “Objects Present Reports” (page 169))

Reports are generated by sending a Web query to the System Reporter database. Each query must

specify a report type from one of the categories listed above. These report types are discussed in

further detail in “Report Types” (page 154).

Each report type also has options that you can use to customize the report results. Not all options

can be used with all report types. See “Report Options” (page 129) to learn which options are

compatible with which report types.
