Support for Asset/CMDB Solutions being in a hierarchy or data being sent by stand-alone replication rules depends on which version of the products/Symantec Management Platform is being used.
For Symantec Management Platform versions 7.5 and 7.1 SP2
It may be desired that Asset/CMDB works on a Child server, or if they are already installed to one, to not have the errors and issues that are occurring happen. This is, however, the way that Asset/CMDB were designed to work and this is not able to be altered. To further describe how this works under the hood, the following information provides a technical explanation of why Asset/CMDB do not support being on a Child server or being used with stand-alone replication rules:
In the past, a customer would set up a parent server with CMS (Client Management Suite, which is the client-facing server that has Core and Inventory Solution, among others, installed) and a child server with AMS (Asset Management Suite, which does not have clients and only has Asset data). This would be done to offload processing to a "secondary" server from the CMS to the AMS, to improve performance on the CMS. However, this is an outmoded way of how Altiris currently works. The last platform this was valid on was the Notification Server 6.0 using inventory forwarding rules. As the Symantec Management Platform 7.1 and higher is no longer designed to enable AMS to be on a child server or use stand-alone replication rules, there's now no valid reason for having an AMS server with a CMS server. Both functions should be on the client-facing server (CMS) only. If the customer is still needing to improve performance on the "main" server, they should look into implementing best practices for Inventory schedules, image deployment, and investigate if task servers (etc.) would benefit the environment, instead of attempting to try to get a CMS to AMS environment to work, as it cannot work like that.
Please Note: Because Asset/CMDB does not support being on a child server or being used with stand-alone replication rules, if the customer has previously set this up and it has worked on some servers but not others, or if it seems to mostly work but some elements such as UI buttons or tasks seem to not work or be enabled, does not indicate that this is working 100%. This is an environment (hierarchy/stand-alone replication rules) that Asset/CMDB are not designed to work with; unexpected issues may occur. As such, Symantec Technical Support is unable to assist the customer in fixing this to work, as there is no method to change this functionality.
For Symantec Management Platform versions 7.1 SP1 and 7.1 (no SP)
For Symantec Management Platform version 7.0
Each Symantec Management Platform server is capable of handling up to 20,000 active client managed nodes when properly equipped and configured. If less than 20,000 nodes are being managed, hierarchy should not be implemented. Refer to the following article for more information about server hardware configuration:
