Because the Cluster Edition supports a single-system image, using a cluster as a remote server has minimal impact on the server sending the RPC request.
If the server sending the RPC is using cis rpc handling, the cluster perceives the inbound request as a regular client connection. The workload manager attempts to route the RPC to the appropriate instance and logical cluster based on the configured routing rules. The workload manager rules may dictate login redirection, as long as the initiating server indicates that it supports login redirection. Adaptive Server 15.0 and later support login redirection for RPC requests.
If the initiating server uses site handlers, the cluster workload manager is bypassed and the RPC runs in the system logical cluster of the instance that accepted the connection.
