Server Tuner

Use Server Tuner to optimize the performance of the OfficeScan server using parameters for the following server-related performance issues:

Download

When the number of clients (including update agents) requesting updates from the OfficeScan server exceeds the server's available resources, the server moves the client update request into a queue and processes the requests when resources become available. After a client successfully updates components from the OfficeScan server, it notifies the server that the update is complete. Set the maximum number of minutes the OfficeScan server waits to receive an update notification from the client. Also set the maximum number of times the server tries to notify the client to perform an update and to apply new configuration settings. The server keeps trying only if it does not receive client notification.

Buffer

When the OfficeScan server receives multiple requests from clients, such as a request to perform an update, the server handles as many requests as it can and puts the remaining requests in a buffer. The server then handles the requests saved in the buffer one at a time when resources become available. Specify the size of the buffer for events, such as client requests for updates, and for client log reporting.

Network Traffic

The amount of network traffic varies throughout the day. To control the flow of network traffic to the OfficeScan server and to other update sources, specify the number of clients that can simultaneously update at any given time of the day.

Server Tuner requires the following file: SvrTune.exe

To run Server Tuner:

• Tools > Administrative Tools > Server Tuner

1. On the OfficeScan server computer, navigate to <Server installation folder>\
   PCCSRV\Admin\Utility\SvrTune.

2. Double-click SvrTune.exe to start Server Tuner. The Server Tuner console opens.

3. Under Download, modify the following settings:

Timeout for client

Type the number of minutes for the OfficeScan server to wait to receive an update response from clients. If the client does not respond within this time, the OfficeScan server does not consider the client to have current components. When a notified client times out, a slot for another client awaiting notification becomes available.

Timeout for update agent

Type the number of minutes for the OfficeScan server to wait to receive an update response from an Update Agent. When a notified client times out, a slot for another client awaiting notification becomes available.

Retry count

Type the maximum number of times the OfficeScan server tries to notify a client to perform an update or to apply new configuration settings.

Retry interval

Type the number of minutes the OfficeScan server waits between notification attempts.

4. Under Buffer, modify the following settings:

Event Buffer

Type the maximum number of client event reports to the server (such as updating components) that OfficeScan holds in the buffer. The connection to the client breaks while the client request waits in the buffer. OfficeScan establishes a connection to a client when it processes the client report and removes it from the buffer.

Log Buffer

Type the maximum number of client log information reports to the server that OfficeScan holds in the buffer. The connection to the client breaks while the client request waits in the buffer. OfficeScan establishes a connection to a client when it processes the client report and removes it from the buffer.

• If a large number of clients report to the server, increase the buffer size. A higher buffer size, however, means higher memory utilization on the server.

5. Under Network Traffic, modify the following settings:

Normal hours

Click the radio buttons that represent the hours of the day you consider network traffic to be normal.

Off-peak hours

Click the radio buttons that represent the hours of the day you consider network traffic to be at its lowest.

Peak hours

Click the radio buttons that represent the hours of the day you consider network traffic to be at its peak.

Maximum client connections

Type the maximum number of clients that can simultaneously update components from both "other update source" and from the OfficeScan server. Type a maximum number of clients for each of the time periods. When the maximum number of connections is reached, a client can update components only after a current client connection closes (due to either the completion of the update or the client response reaching the timeout value you specified in the Timeout for client or Timeout for Update Agent field).

6. Click OK. A prompt appears asking you to restart the OfficeScan Master Service.

• Only the service restarts, not the computer.

7. Click Yes to save the Server Tuner settings and restart the service. The settings take effect immediately after restart.

Click No to save the Server Tuner settings but not restart the service. Restart the OfficeScan Master Service or restart the OfficeScan server computer for settings to take effect.
