What Is HVR Hub

Question

What is HVR hub?

Environment

HVR 5

Answer

In a replication setup, the HVR hub is an installation of HVR that orchestrates the data replication between the source(s) and target(s).

• Every HVR replication must have a hub, i.e. an installation of HVR that plays the role of the hub.
• There is only one download/installation of HVR per operating system, independent of whether the installation will be playing the role of a hub.
• The hub installation must run a scheduler service to manage jobs that move data between databases/locations (capture jobs, integrate jobs, refresh jobs, compare jobs). An installation of HVR that does not play the role of a hub is typically referred to as an agent installation, which does not run a scheduler service.
• The HVR hub must connect to a database – the "hub database", which stores the metadata repository consisting of 15 relational tables. The hub database can be running on the same machine as the HVR hub, or it can be a remote database (e.g. a database service in the Cloud, or a database on another server). To establish the connection to the hub database, HVR must have access to connectivity libraries of the specific database. For the requirements per database, refer to the release notes hvr.rel available in the HVR_HOME directory.
