In case of a distributed installation, the IUCLID 5 client offers support to prepare the IUCLID 5 system for shutdown because of maintenance.
To prepare the system for maintenance, do the following steps:
Log in as SuperUser
Go to the "File" menu, select "Adminstrative tools", then "Shutdown server". The following dialogue will appear:
In the lower part of the pane, the list field Current
users
shows all users currently connected to the IUCLID 5
server.
Enter a custom message in the Message
field.
When you press the Shutdown system
button, this
message will be sent immediately to all connected users. If you leave
this field blank, the default message "Server shutting down. Please save
your work and log off." will be sent.
In the Timer
field, select a time after that
all connected users will be automatically logged of. The default is
15sec.
After the timer is up, the session for all logged in users, except the SuperUser will be terminated. All unsaved work of these users will be lost!
If you check the option prevent futher logins
the system immediatly refuses new log ins to the system. Users trying to
log in will get a message, that the system is currently in maintenance
mode and log ins are refused. If you do not check this option, re-log
ins will be able after the timer is up.
Press the Shutdown system
button.
If the timer is up, you will get the message "Server is now prepared for shutdown. Please logout and shutdown the server". The system is now save to be shut down completely or to do some maintenance, which should not be interrupted by users (like backup / restore or changes in user roles).
After the time is up and all users are logged off, only if you
have checked prevent futher log
ins users can't log
in again. If this option was not checked, users can immediatley log in
again.
The maintenance mode can be resolved in two ways:
Restart the server application on the server.
As SuperUser, call again the
Server shutdown dialogue, set a proper message like "System available
again.", uncheck the option prevent futher logins
and
press "Shutdown server
". After the timer is up, the
system will be in normal operational mode.
