Short Description: Adjust the Availability Index calculation to match the speed of your server.
SERVER_TRANSINFO_RANGE is used to adjust the Availability Index calculation to match the speed of your server.
To adjust the Availability Index calculation for your server using this variable, monitor your system during a period of heavy usage and note the values of Expansion Factor. Use the console command
show stat server.expansionfactor
Select a value for SERVER_TRANSINFO_RANGE such that 2 raised to the power SERVER_TRANSINFO_RANGE is a reasonable upper bound for expansion factor values. For example, if SERVER_TRANSINFO_RANGE=6, then we expect that the expansion factor values will not rise about 64.
Monitor your system during periods of heavy usage to note what value of Availability Index you want to set for your threshold. Select a value which matches the drop in response time at which you want failover to occur.
There is no kown UI setting for this notes.ini variable. But you can specify this setting in the notes.ini settings tab of the configuration settings document.
