Tips to Improve Performance

Windows 2000 for the Java application when running Windows XP, or XP when running

Windows 7 removed the problem (For more information about running Java in

Windows2000 Compatibility mode, see the Quick Start Guide).

• Do not start services on the iControl Application Server that are not required. By default,

the Densité Manager, the RMI Daemon with lookup service and the GSM service are

configured to start at boot time. All other services are stopped.

• Large systems require a proper system configuration and load balancing. Typically one

Densité Manager is assigned no more than 150 streams. A thumbnail, ALM, scope or CC are

all separate streams. If one card provides a thumbnail and one ALM, then one Densité

Manager can handle 75 cards. Up to three Densité Managers can be configured for load

balancing.

• The lookup service should preferably not be running on heavily loaded Application

Servers.

• When there are more than two Application Servers within the same subnet, keep a

maximum of two lookup services running.

• When a Kaleido-K2 is on the same subnet as an Application Server, the lookup server on

the Kaleido-K2 must be stopped, and the one on the Application Server must be used

instead. Refer to the Kaleido-K2 documentation for instructions on how to stop a Kaleido-

K2 lookup service.

• If a network device does not exist (e.g. router, DNS, WINS) in the network environment, it is

vital to remove its settings from the client PC’s network configuration, and from the

Application Server. Failure to do so will introduce unnecessary network time-out delays.

• The presence of a DNS in the network environment is preferable to speed up reverse host

name lookup, used by part of the iControl infrastructure. If this is not possible, then specify

the host name of the Application Server in the PC client Windows host file

(

C:\Windows\system32\etc\drivers\hosts). The Application Server can also play the

role of a DNS server or forwarder.

• Ensure that the port settings on switches are set correctly for optimal performance. The

Application Server’s Ethernet ports eth0 and eth1 are configured to auto-negotiate.

Negotiation with the switch must be 100 Mbits full duplex, or 1000 Mbits full duplex, for

optimal performance.
