OEM 12c Web Tier and OMS to start manually

Question

Hi, when I look at the boot log I see the WebTier and OMS starting automatically. Is there a setting I can change so they would not start during the boot.
I'd like to have in them in the manual startup mode. Thanks.

Thanks. I was thinking about some emctl setting that would put the oms and agent into manual mode but your suggestion would also work.
Unfortunately, when looking at the gcstartup file I see a standing out line that I could comment out to prevent automatic startup.
#!/bin/sh

#Function. Parameter 1 is the return code
#Para. 2 is text to display on failure.
if [ "${1}" -ne "0" ]; then
echo "ERROR ${1} : ${2}"
#as a bonus, make our script exit with the right error code.
exit ${1}
