EPICenter Server Issues
EPICenter Concepts and Solutions Guide 171
Exceeding the first limit (>20 traps in 28 seconds) is rare, and should be considered abnormal behavior in
the managed device. If you are managing a large number of devices, you may reach the total (275) limit in
normal circumstances. If you are managing more than 1000 devices, it is recommended that you increase
the total number of traps to 500.
The trap processing limits can be changed through server properties in the Administration applet. See
Chapter 15 in the
EPICenter Reference Guide for more information on setting EPICenter server properties.
Problem: Under Solaris, an error occurs when attempting to enable the EPICenter Syslog server
function.
By default, Solaris runs its own Syslog server. This causes an error “Syslog Server unable to start: Address
already in use” when you attempt to enable the EPICenter syslog server. You must first stop the Solaris
syslog server in order to have EPICenter act as a Syslog receiver. To stop the Solaris Syslog server, use the
command:
/etc/init.d/syslog stop
Problem: EPICenter is not receiving traps.
If the IP address of an EPICenter host is changed via DHCP while EPICenter is running, the system will
not receive traps. To fix the problem, you can do a manual sync on all devices, or restart the EPICenter
server.
Problem: On a Windows system with multiple NICs, EPICenter may not receive traps or be able to
upload or download configuration files or images.
In Windows, in a multiple NIC cards environment, the IP address that EPICenter gets as the primary IP
address is determined by the order in which the network connection is listed in the 'Adapters and
Bindings' tab in Advanced Settings, and may not be the NIC that is actually connected to the management
network. There is no guarantee that the primary IP address that gets registered as a trap receiver on a
switch is the IP address of the NIC that EPICenter actually uses to communicate.
You may be able to work around this by changing the order of the IP addresses in the Adapters and
Bindings tab in the select the primary IP address for EPICenter to use:
1 From the Start menu select Settings , then select Network and Dial-up Connections . You can also open
the Network and Dial-up Connections window from the control Panel.
2 From the Advanced menu , select Advanced Settings...
3 Select the Adapters and Bindings tab, which shows the connections listed in order.
4 Select the connection you want EPICenter to use, use the up and down arrow buttons at the right to
move it to the top of the list, then click
OK
5 Restart the EPICenter server.
Problem: Policy Manager button does not appear in the Navigation Toolbar.
The EPICenter Policy Manager is a separately licensed module, and requires installation of a separate
license key through the
instlic
license key utility. When you purchase the right to use the Policy
Manager applet, you will receive an activation key, found on the License Agreement included in your
software package. This key starts with “AC,” and can be used to obtain a permanent license key. You do
not need an activation key to obtain an evaluation license key.
To obtain a license key, use your browser to connect to the license page at

You can obtain an evaluation key or a permanent key
through this page. You will need your activation key to obtain a permanent license key. In either case, you
