Scalability, Fault Tolerance, Maintenance, And Sizing Of The Database Server; Sybase - Novell ZENWORKS 10 CONFIGURATION MANAGEMENT SP3 - SYSTEM PLANNING-DEPLOYMENT-BEST PRACTICES GUIDE 10.3 30-03-2010 System Planning Manual

Have a dedicated set of Satellite devices for software and patch distributions if the
frequency of distributions is high. You want to randomize the distribution of software and
avoid massive numbers of devices hitting the Satellite device at the same time.
Randomize the refreshes of managed devices at the site with Satellite devices.
For smaller sites (fewer than 250 devices):
Have multiple Satellite device that share load and responsibility.
Do not be significantly concerned about designating specific servers for specific
functions.
Randomize the refreshes of managed devices at the site with Satellite devices.
3.4 Scalability, Fault Tolerance, Maintenance,
and Sizing of the Database Server
The primary considerations about database scalability include:
How many devices are you managing? If you need to scale past 5,000 devices, you might want
to consider putting the database in either Oracle or Microsoft SQL Server.
Can you leverage clustering technologies to achieve fault tolerance for the database? This
ensures that the database is always available.
The following table lists the number of devices different databases can handle in a production
environment:
Database Platform
Sybase (embedded)
Sybase (remote)
Microsoft SQL Server 2005
Oracle 10g
Ensure that you use the vendor database backup tools to regularly back up the database. This ensures
that if the database is lost, you can restore from a backup and get back to operations quickly.
The following sections highlight recommended best practices when managing and maintaining your
Database Server:

3.4.1 Sybase

One of the most important aspects of Sybase database maintenance is regular backups of the
database files. You can use zman commands to back up the Sybase database. For more information,
