Hi,
I want to edit a script ,it will be executed automatically when UNIX start , But Just once.
(1) Which directory or system file I should put this script into that let it executed when UNIX start ?
And if it have any error or log when executing, where system will be save it?
(2) If I edit a sciprt to start Oracle Service(svrmgrl and lsnrctl)when UNIX start, Can I use "su" -command to change cureent user form "root" to "oracle" and change it back in my script.

Hi k.y

you can do very easily . by adding your script in /sbin/rc /S##<script name> where ## is appropriate number which should not conflict with others . if you want to start the process
with only from oracle user while system boots that also possbile .

2) you can start this with inetd daemon . there is a file /etc/inetd.conf in this you can mention the desired user name also . to make it working you have to mention the proper listener
service name which should present in the /etc/services also.

Thanks and regards

1> Put the script on corrresponding startup level as /sbin/rc#.d/ directory there. And give the execution permission to that file, else it will not be executed. See some other files located at /sbin/rc#.d/ directoy. It is having standard format there. IF you want to try before startup try it on shell command there right now. If u have problem, that will be good to avoid during startup.

To check the script problem try to run with debugging mode as set -x on shell first.

Error log / startup information's will be in /etc/rc.log file there.

2> Yes. You can do it as su - -c to be executed there.

If you are running su from root then no passwd needed there. After execution of su with command it will return to root there.

See man rc, su
