Limit Device Sessions (QLMTDEVSSN)

The Limit Device Sessions (QLMTDEVSSN) system value specifies whether the number of device sessions allowed for a user is limited.

This value does not restrict the System Request menu or a second sign-on from the same device. If a user has a disconnected job, the user is allowed to sign on to the system with a new device session.

Note: This system value is a restricted value. See Security system values for details on how to restrict changes to security system values and a complete list of the restricted system values.
Table 1. Possible values for the QLMTDEVSSN system value:
Value Description

The user is not limited to a specific number of device sessions.


The user is limited to a single device session.

2 - 9

The user is limited to the specified number of device sessions.

Recommended value: 1 (Yes) is recommended because limiting users to a single device reduces the likelihood of sharing passwords and leaving devices unattended.

Note: Limiting device sessions can also be specified in individual user profiles.
