Setting Resource Limits

About this task

Webspace allows administrators to prevent users from starting new sessions when certain resource limits are exceeded on a Webspace Server. These limits help administrators prevent servers from becoming loaded to the point where users experience performance problems and random resource allocation failures. You can also limit the total number of session connections to the Webspace Server. And, you can prevent users from logging on when the available physical memory or virtual memory on a server falls below a given value.

These resource limits are especially important in a Relay Server configuration. For each dependent server in a Relay Server configuration, you must configure these limits.
