SUMMARY:
This Knowledge Base entry gives a brief explanation of how to stop and start one application under UNIX without need to stop the computer.
SOLUTION:
The examples that follow are valid on SCO platforms. Other platforms
may have different structures but the same concept applies.
-- The /etc/inittab is the table used for UNIX to boot the system.
If you display this file, you can see:
r0:056:wait:/etc/rc0 1> /dev/console 2>&1 </dev/console
r1:1:wait:/etc/rc1 1> /dev/console 2>&1 </dev/console
r2:2:wait:/etc/rc2 1> /dev/console 2>&1 </dev/console
r3:3:wait:/etc/rc3 1> /dev/console 2>&1 </dev/console
sd:0:wait:/etc/uadmin 2 0 >/dev/console 2>&1 </dev/console
fw:5:wait:/etc/uadmin 2 2 >/dev/console 2>&1 </dev/console
rb:6:wait:/etc/uadmin 2 1 >/dev/console 2>&1 </dev/console
-- If you want to stop/start one application, for example lp, tcp, nfs, oracle, X25, etc, you can follow this procedure:
Example:
Stop lp services:
login root
cd etc/rc2.d
ls -lp
