4D Server v11 SQL: Beyond the Limits

Tue, 2009-07-21 (All day)

See what's new in 4D Server v11 SQL and 4D v11 SQL Release 2.

Remote Administration

Reach your admin window remotely, or open it for your users using the OPEN ADMIN WINDOW command. Restart your servers remotely. (After compacting, for example.)

Query by Formula - Client/Server

The speed of Query By Formula execution on the server side under 4D v11 SQL.

In 4D 2004, a Query by Formula is executed on the client end. This means that every record must pass over the network to have a formula applied, and to determine if it will be part of the selection.

When the logic of the request allows it, 4D v11 SQL will perform queries directly on the server to avoid extraneous loads on the network. Only the selection is returned to the client end, as with a classic query.

Let’s go back to the formula for measuring distance used in the test QUERY BY FORMULA (standalone).


4D Server v11 SQL Scalability test

How many simultaneous, active clients can 4D Server handle? This laboratory scalability test examines the limits of a real application on 4D Server v11 SQL.

Since the recent announcements about scalability in 4D v11 SQL Release 3, especially in regards to those helped by improved management of multi-processor operations, many people have had questions about the number of simultaneous clients that can connect to 4D Server.

Admin Window

A complete administration window gives you a heads-up view of all 4D Server metrics and direct access to primary server maintenance procedures.

A complete and ergonomic Admin Window gives you:


• Graphical display of all 4D Server activity metrics

• Separate panels for detailed views of users and processes

• New colors and icons to visually distinguish grouped elements

• Query/filter displayed information

• Direct access to primary maintenance procedures (verification, backup, compacting, etc.)
