AIX timezones - a way around rebooting?
Hi,

I've got a bunch of IBM AIX 5L 5.3 and 5L 5.2 servers here that I've inherited from my predecessor in a new job, and I'm trying to sort out their timezones. A number of them need to have their timezones changed to the correct setting - it would appear that they were not configured properly in the first place.

Ordinarily, this would not be a problem - edit the /etc/environment file and reboot. Except that these AIX servers are 24/7/365 production servers, and cannot be rebooted. Therefore, I need a way to tell AIX to re-read the /etc/environment file and set the system timezone properly WITHOUT having to reboot.

Is this even possible?

reboot

REBOOT(8)						      System Manager's Manual							 REBOOT(8)

NAME

       reboot - reboot the system immediately

SYNOPSIS

       reboot [-f]

DESCRIPTION

       Reboot  can  be	used  to  reboot  the  system  after  installing a new kernel.	It does not inform the users, but does log it's actions in
       /usr/adm/wtmp and /usr/adm/authlog.  The system is then rebooted with the reboot(2) systemcall.

       If the -f flag is not given then all processes are sent terminate signals to give them a chance to die peacefully before the reboot() call.

       If the wtmp file exists, reboot logs itself as if it were a shutdown.  This is done to prevent last(1) from talking  about  system-crashes.
       Reboot is registered as is in the authlog file.

       Reboot can only be executed by the super-user.  Any other caller will be refused, either by reboot(8) or by reboot(2).

SEE ALSO

       reboot(2), shutdown(8), halt(8), boot(8).

BUGS

       The  error message's given by reboot are not always useful.  There are several routines that can fail, but which are not fatal for the pro-
       gram.
