    • Product/Version:
    • Apex One All.All

Summary

You can specify certain OfficeScan/Apex One clients/agents to act as local update sources for other clients/agents.

For instance, if your network is segmented by location and the network link between the segments experiences heavy traffic load, we recommend allowing at least one client/agent for each segment to act as an Update Agent.

 
  • Make sure that the Update Agent machines have at least 300 MB available disk space.
  • The maximum number of customized update sources for an OfficeScan/Apex One client/agent allowed is 1024.
  • The maximum number of concurrent client/agent update requests that an Update Agent can handle is 250. This may differ slightly depending on the hardware specifications of the machine.
  • Excessive Update Agents can actually harm performance. It is recommended to only configure the Update Agents that are required.

  • If unable to update from all entries, the client does and checks the following.

    On the Agent Update Source Page the “OfficeScan agents update the following items from the OfficeScan server if all customized sources are unavailable or not found” option.

    If enabled, the client updates from the OfficeScan server the options selected below it:

    • Components
    • Domain Settings
    • OfficeScan agent programs and hot fixes
  • If the option is disabled, the client then tries connecting directly to the Trend Micro ActiveUpdate server if any of the following is true:
    • For OfficeScan 11.0:

      In Agent > Agent Management > Settings > Privileges and Other Settings > Other Settings tab > Update Settings, the option "Clients download updates from the Trend Micro ActiveUpdate Server" is enabled.
