IBM Informix OnLine Database Server Administrator’s Guide

Take OnLine gracefully from online to quiescent mode when you want to
restrict access to OnLine without interrupting current processing.

If you are user informix, you can take OnLine gracefully from online to
quiescent mode from within

DB-M

onitor or from the command line. If you

are root, you can only use the command-line option.

After you execute this task, OnLine sets a flag that prevents new database
server processes from gaining access to OnLine. Current server processes are
allowed to finish processing.

Once you initiate the mode change, it cannot be cancelled.

From within

DB-M

onitor, select the Mode menu, Graceful-Shutdown option

to take OnLine gracefully from online to quiescent mode.

DB-M

onitor displays 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, execute tbmode -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, execute tbstat from the
command line. The header on the tbstat output gives the current operating
mode.
