Procedure

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 toa 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.

     Note 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.

   Note Only the service restarts, not the computer.

7. Select from the following restart options:
   • 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.
