Lock a Client to Prevent Logons

You can lock a system at the OS level by running: tp locksys pf=tpprofile

Example: To lock your DEV system enter this command:
tp locksys DEV pf=tp_domain_dev.pfl

Users will get this message if they attempt to log on: "Upgrade still running. Logon not possible".

Notice that the message is not exactly accurate. TP locksys is mainly used during release upgrades so the message is kind of generic.

To unlock the system,
run: tp unlocksys pf=tpprofile


Only SAP* and DDIC can log on to any of the clients in the system that has been locked.
