RELOAD_SPREAD
Updates cluster changes to the catalog's spread configuration file. These changes include:
- New or realigned control nodes
- New spread hosts or fault group
- New or dropped cluster nodes
This function is often used in a multi-step process for large and elastic cluster arrangements. Calling it might require you to restart the database. You must then rebalance the cluster to realize fault tolerance. For details, see Defining and Realigning Control Nodes in the Administrator's Guide.
