Reference this table while making configuration changes under this tab:
Field/Button Description User input/Default Loadbalance Type Offers two load balancing options: Dynamic or Round Robin. Choose a load balancing type. Default is Dynamic. Prep-Exec Handling
ScaleArc generates its own prepare handles and maintains a mapping of client-side and server-side handles. Enable this setting to support failover, Read/Write split, routing, and caching for Prepare-Exec queries.
Once enabled, connections with outstanding prepares cannot be put in passthrough and may cause invalid handle error on the server.
Turning this option OFF routes all Prepare-Exec traffic to the Read/Write server and connection passthrough works as expected.
Turn ON/OFF. Default is ON.
