You may then change the port values for these property entries and restart the Application
Server. Special setup (outside the scope of this document) is necessary to run a web server on
port numbers lower than 1024 on many operating systems.
CAUTION:
Do not change the system time while the Application Server is running. If you must change the system
time, shut down the server before the change, and restart it afterwards.
Proactive Runtime Management
To insure OpenManage Network Manager continues to run smoothly long after you have installed
it, best practice is to take the following precautions.
• Make sure you configure database archiving policies (DAPs) to suit your system, particularly if
you have device messaging (typically alarms and syslog) that threaten to fill your database.
• Occasionally check the Audit Trails to ensure DAPs are running properly.
• Configure your syslog and alarm events to only catch significant ones.
• Configure devices to suppress their own messages if these messages are unimportant.
Updating an Existing Installation
Always consult the manuals and CD contents for upgrade instructions. Database changes may
require a migration step to preserve your data when moving to a new version.
Best practice is to perform a complete backup of your system before attempting an upgrade.
Provided you are dealing with the embedded MySQL database, some packages installs may prompt
you to automatically back up the database. The wizard can also prompt you for a location. The
filename is
backup.sql .
If you do an update installation, even if you elect not to rebuild the database, installation always
reseeds the system settings. If you have changed the default settings, you may want to export these
before proceeding.
After files install, select whether you want the installation program to rebuild the database content,
otherwise, the application keeps the existing one. The installation wizard begins copying the
needed files.
If your installation fails, see
setup.log , db_setup.log or app_setup.log in the destination
directory for the installation for messages that may help fix the failure.
Cancelling the Installation
Once the installer finishes transferring files, the application is installed; you cannot cancel
installation. Short of killing the installer process, you cannot cancel database initialization or
component installation and seeding. The installer considers this portion of its work system
