# Calculating session limits

You can calculate session limit values for DRDA access.

## About this task

You might have to derive a precise figure for your session limits (DSESLIM). For example, if you specify a very large number for your session limits and you are running short of space, it might help to calculate a number closer to what you actually need.

## Procedure

To calculate the session limit for a specific mode:

For DRDA access,
determine the maximum number of concurrently active applications that
use the mode to and from the remote system.

## Example

For example, suppose location A has a maximum of 3 DRDA access applications that can run concurrently on Mode1 to other locations. Also suppose that a maximum of 10 DRDA access applications can be incoming to location A on Mode1. In this case, Mode1 should support 13 sessions for DRDA access applications.
