3-10 IBM Informix OnLine Database Server Administrator’s Guide
Gracefully from Online to Quiescent
Gracefully from Online to QuiescentTake OnLine gracefully from online to quiescent mode when you want to
restrict access to OnLine without interrupting current processing.
If you are userinformix, you can take OnLine gracefully from online to
quiescent mode from withinDB-Monitor or from the command line. If you
areroot, you can only use the command-line option.
After you execute this task, OnLine sets a flag that prevents new database
serverprocesses from gaining access to OnLine. Current server processes are
allowed to finish processing.
Once you initiate the mode change, it cannot be cancelled.
From DB-Monitor
Fromwithin DB-Monitor, select the Mode menu, Graceful-Shutdown option
to take OnLine gracefully from online to quiescent mode.
DB-Monitordisplays a list of all active users and updates it every five seconds
until the last user completes work or until you leave the screen.
From the Command Line
From the command line, executetbmode -s or tbmode -sy from the
command line to take OnLine gracefully from online to quiescent mode.
A prompt asks for confirmation of the graceful shutdown. The-y option to
tbmode eliminates this prompt.
To verify that OnLine is running in quiescent mode, executetbstat from the
command line. The header on thetbstat output gives the current operating
mode.
For further information about thetbmode utility, refer to page7-64.
