OS patch compatibility for AOS and GR nodes

  • Last UpdatedJul 08, 2026

Ensure that all Application Object Server (AOS) nodes and the Galaxy Repository (GR) node that run on the same operating system use the same operating system patch level. For example, if all your GR and AOS nodes are running on Windows 11, all the nodes must be at the same patch level.

If patch levels are inconsistent, the IDE cannot open objects on remote AOS nodes.

This requirement applies only to nodes that run the same operating system. It does not apply if the GR and AOS nodes run different operating systems, for example, one node is running Windows 11 and other node is running Windows Server 2022.
