whether the licensing Dongles provided are cold pluggable or hot pluggable?
We don’t recommend hot-swapping dongles (hardware keys) - see the "caution" at the top of page 30 in our licensing manual: mgc_licen.pdf. With that being said, we've found that as long as you end all programs/processes/services that rely on the dongle(s) before swapping them out - for example: a Mentor application licensed to the dongle, or a license manager based on the dongle FLEXID - then you should be fine. If you do run into any problems with this procedure you should shut down the machine before swapping the dongles.
I have done as Andrew suggested. I shutdown the license manager and made sure the services were stopped before I removed it. No issues seen. I have not done this for Mentor specifically but with numerous other license managers but I would assume that it behaves similarly since they all use flelxm.
let me know for wchich type of Dongle you used? is it USB or parallel port dongle??
and has light turned off after ending all the processes?(in case of USB dongle)
I have done it with both. The parrallel was on WIndows 2000 but the USB has been on 2003. And if I remember correctly the USB light does turn off.
But i came to know that as long as the light in the USB dongles glows we should not remove the dongle(i guess the light indicates that it is in use)
will the light go off if we end all the processes related to the dongle??(if it is a server license we can end the server in lmtools or in the task manager,but i am surprised what we can do if it is a node locked license tied to the dongle)
P.S: i can try this at my end but unforunately i dont have any dongles with me at this time.
I have found that the light on my USB dongle mostly stays on even when it's not in use. The only time I've seen the light off is after I remove the driver and the dongle, and plug it into a port that I have not used before. The light will stay off until I reload the driver. Another factor could be the power settings; I have mine set to not power down the USB ports (this avoids the potential for licensing errors after the machine wakes from a sleep/hibernation state).
As long as all programs relying on the dongle are shut down before unplugging the key, I don't foresee any problems.
