Hello,
I have a problem on lock management :
1/ My UI is locking a DP for the "_original" attribute, but sometimes when the UI is stopped, the lock is not released.
2/ Moreover, the host column in PARA windows , it's displayed "unknown".
3/ The problem comes just for remote UI. UI which are running on the server have not this problem.
The problem is not systematic, when we switch from a server to the other (Server2 to Server1), the lock's attributes
is correctly displayed and lock is removed! why?
regards
Emmanuel

Re: Lock is not released after UI shutdown
Just to precise, I'm working with the version 3.12 (without patch)
to add some information, the problem is often seen on server 2, never on server1

Re: Lock is not released after UI shutdown
Hello,
at my tests the locks have been released by the event manager when the UI looses the connection. No matter if the UI is stopped in a normal way (SIGTERM) or by killing the UI (SIGKILL).
Can you please check if the event manager has detected that the UI connection was lost.
How did you check that only one server has released the locks?

Re: Lock is not released after UI shutdown
Hello,
The UI is often stopped with ALT+F4 (SIGKILL I presume). In all case, the check on the _lock is only done on the Master (Server 1 or 2), but I don't know why, the server 2 doesn't react
as the server 1. Mousser Kerkeni (from ETM) has also seen a difference of behavior between the 2 servers.
(Note : we have used 2 methods to install our project
1/ First copy the directory project and register it in the Administration Project windows
2/ Create it through the Wizard)

Re: Lock is not released after UI shutdown
Hello,
I have repeated the tests using a redundant system.
Even when stopping the UI with the SIGKILL option the locks have been released.
Have you checked if the event manager has detected a lost connection to the UI manager?
