Description

The Domino server calculates its availability index (0–100 %) based on the average transaction time within a sliding time window. Server_Transinfo_Range defines how long this window is.
Short values (e.g. 30 s) react quickly to load spikes but are jittery. Longer values (120–300 s) smooth out the curve and yield more stable load-balancing decisions for cluster failover.

Example configuration

Server_Transinfo_Range=120

Notes & pitfalls

  • Value in seconds.
  • Pairs with Server_MaxConcurrentTrans, Server_Min_Possible_Trans_Time, Server_Max_Possible_Trans_Time.
  • Observe the effects via show statistic Server.AvailabilityIndex and show performance.
  • Important for cluster load balancing – values that are too short can cause failover flapping.
  • The change takes effect after a server restart.
