A replica group represents an abstract grouping of identical, or very similar, object adapters. An object adapter joins this group by setting this replica group ID in its Replica Group field.
The Replica Properties panel offers the following fields:
Load Balancing Policy
The load-balancing policy used by IceGrid when resolving the Replica Group ID in proxies. Must be one of:
Policy | Description |
---|---|
Adaptive | Returns the endpoints of the object adapters whose nodes report the lowest load-average (on Linux/Unix) or CPU utilization (on Windows). The actual load-average or CPU utilization value of each node is multiplied by the node's load-factor for this comparison. See Load Sample below, and Node. |
Ordered | Returns the endpoints of the object adapters with the highest priority. See Adapter. |
Random | Returns the endpoints of object adapters selected at random. This is the default policy. |
Round-robin | IceGrid puts all the object adapters in a list, and for each new resolution, it returns the endpoints from the next How many Adapters items on this list. |
