Majority of the scripts, which you want to startup certain services during the boot process itself are usually placed (CentOS, RHEL, OUL(Oracle Unbreakable Linux)) in /etc/init.d folder
We had a requirement to disable the automatic startup of Oracle database, which was a part of Oracle Vision Instance 12.1.3
The vision database node server on Oracle linux, starts up the database services during the boot process itself, thus delaying the booting process.
After a long scrutiny (as I am not very familiar with Linux) I found that during the boot up, one particular service “ebizdb” was being executed and I found a script with automatic execution within “/etc/init.d” folder
Recently I have learned that I could change a .sh script using “chmod” command to executable so that I could call it without using “./” and the syntax was
chmod +x myscript.sh
Just keeping my fingers crossed (make a note of my acceptance that I am not a linux geek) I tried the following
chmod –x ebizdb
Prior that I tried
chconfig ebizdb off
and kept on receiving error message stating “service ebizdb does not support chkconfig”
The job was done by just the script’s behavior from executable to non-executable.
Hope this helps few out there, who are Linux noobies like me!
