Server_TransInfo_Range
Syntax: Server_TransInfo_Range =value

Description: SERVER_TRANSINFO_RANGE is used to adjust the Availability Index (AI) 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


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 AI you want to set for your threshold. Select a value which matches the drop in response time at which you want failover to occur.

You can also use the console command


to display the server's expansion factor and AI histories and suggest an appropriate value for this variable.
