Operating OnLine

Take OnLine immediately from online to quiescent mode when you want to
restrict access to OnLine as soon as possible. Work in progress can be lost.

If you are user informix, you can take OnLine immediately 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.

A prompt asks for confirmation of the immediate shutdown. If you confirm,
OnLine sends a disconnect signal to all database server processes that are
attached to shared memory. The processes have 10 seconds to comply before
OnLine terminates them.

OnLine users receive either error message, -459 indicating that OnLine was
shut down, or error message, -457 indicating that their database server
process was unexpectedly terminated.

The tbinit daemon process performs proper cleanup on behalf of all database
server processes that were terminated by OnLine. Active transactions are
rolled back.

From within

DB-M

onitor, select the Mode menu, Immediate-Shutdown

option to take OnLine immediately from online to quiescent mode.

From the command line, execute tbmode -u or tbmode -uy from the
command line to take OnLine immediately from online to quiescent mode.

A prompt asks for confirmation of the immediate 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.
