Hi all,
Is there any possibility to restart the licence server without kill all the current baan sessions?

How about the following:
licmon6.1 -k
rc.start_licd

Do you see any problem?
Thank you in advance.

Restarting license after license killing takes some time . If during this time , new sessions are run by user , it creates problem. Session is not started . This can be a problem when there is automation and lot of sessions are run in sequence.

Also when the license daemon is restarted , the only active bshells are registered. So some inactive bshell during this time may not be able to work due max user error.

On unix certain scripts (alg6.1) are available to kill the individual bshells . Also in latest porting sets u can recover the lost license using licmon6.1 -c command . This may help you.

Yes, it will be helpful info.
Thank you.
