When needing to adjust when a sleeping client should be timed out and dropped from the server, you can modify the database parameter 98 the command SET DATABASE PARAMETER(98;seconds) where the 2nd argument is the number of seconds before the sleeping client is dropped.

For example, if we want a sleeping client to be timed out after 30 minutes, the command will be placed in the On Server Startup method.

SET DATABASE PARAMETER(98;1800)

This command can be useful in situations where there are multiple sleeping clients taking up seats on the server when other clients need to log on without having to manually drop the sleeping clients via server admin window.
