Apex One Server and Security Agent Update | Trend Micro Service Central

Views:

The Apex One server downloads most of the components that agents need. The only component it does not download is the Smart Scan Pattern, which is downloaded by smart protection sources.

If the Apex One server manages a large number of agents, updating may utilize a significant amount of server computer resources, affecting the server’s stability and performance. To address this issue, Apex One has an Update Agent feature that allows certain agents to share the task of distributing updates to other agents.

The following table describes the different component update options for the Apex One server and agents, and recommendations on when to use them:

Table 1. Server-Agent Update Options
Update Option	Description	Recommendation
ActiveUpdate server > Server > Agent	The Apex One server receives updated components from the Trend Micro ActiveUpdate server (or other update source) and initiates component update on agents.	Use this method if there are no low-bandwidth sections between the Apex One server and agents.
ActiveUpdate server > Server > Update Agents > Agent	The Apex One server receives updated components from the ActiveUpdate server (or other update source) and initiates component update on agents. Agents acting as Update Agents then notify agents to update components.	If there are low-bandwidth sections between the Apex One server and agents, use this method to balance the traffic load on the network.
ActiveUpdate server > Update Agents > Agent	Update Agents receive updated components directly from the ActiveUpdate server (or other update source) and notifies agents to update components.	Use this method only if you experience problems updating Update Agents from the Apex One server or from other Update Agents. Under most circumstances, Update Agents receive updates faster from the Apex One server or from other Update Agents than from an external update source.
