Chapter 2 Fault Tolerance and Load Balancing in a Rendezvous Administration Domain : Multiple Load-Balanced Servers Spanning Subnets

Multiple Load-Balanced Servers Spanning Subnets
You can use the mechanism discussed in Administration Domain Spanning Subnets to set up an administration domain with multiple load-balanced servers.
To successfully work in this scenario, follow these steps:
1.
2.
Set up the tibcoadmin_domain.tra file for each server to have a repo.prefixRegionalSubject value. This is optional.
The repo.prefixRegionalSubject property is used to identify and give preference to local servers.
If this optional property is set, servers in load-balancing mode listen on the extra read subject that incorporates this region. If an optional region subject is set for a client, the client directs read operations to that subject first. If no server is available, then the client retries using the regular (non-prefixed) read subject. However, deployment does not use this attribute so the repoURL values in each client’s property (.tra) file must be updated each time a deployment occurs to take advantage of this.
