Help [URGENT]

losintikfos · 08-22-2008, 09:22 AM

Hi Experts,

I am trying to write a shell script to load JAVA_HOME at startup. Can someone tell me how to go about it? and which directory i should place my script in to run at startup.

Please help!

Routines (scripts) that will run at startup can be found in /etc/rc.d/rc.local or do the full Sys V style init stuff.

JAVA_HOME is more like an environment variable for users, placing this in an rc.local or startup script isn't going to do anything for you. You should place this in the global /etc/profile or in each users individual .bash_profile or .bashrc.

And next time use a more descriptive thread title, "Help [URGENT]" doesn't describe your problem and members here help people like you in their own free time, you're issue is no more important than the next members so don't tag threads as urgent.

Thanks david!

Can you post me a sample script for loading JAVA_HOME at runtime please - help if you've got one.

See my post, adding JAVA_HOME to a startup script isn't going to help you.

Simply do this in /etc/profile or your users /home/user/.bash_profile:

JAVA_HOME=/path/to/java

trickykid i absolutly take your advice - won't happen again. also i think what you saying is right! .bashrc will do the trick for the enviromental variable setting - very please with that.

Quick question! do you have any sample script that will execute java class at startup?
!
for example java -classpath /root/Download/sforceAPi/sforceAPP/ Server.class

That you could probably place in the rc.local script usually found in /etc/init.d or /etc/rc.d, depending on what OS you are using and where the startup scripts are located.

i am using RedHat tricky! do you think it would be init.d or rc.d?

losintikfos · 08-22-2008, 09:50 AM

sorry tricky! i think i found the rc.local in rc.d so will place the java string to run the class in and restart my server to test it.

Cheers!

Hi Experts,

I have created a startup script call rc.loop.
I am currently running RedHat so have put the script in etc/rc.d/ area.

My question is will it run as part of the script at startup?

Thanks

I do not think so. If you include it in rc.local, it will, though.

You could add this file to the /etc/readahead.early.files

Just make sure it's executable. You could add it after the /etc/rc.d/rc.local in the file to get invoked after rc.local

trickykid · 08-22-2008, 12:06 PM

Sorry, the readahead.early.files is just a sanity check which I like to add startup scripts to, etc. To have rc.loop start, you have to create a script to invoke it as well. You can add it to rc.local but it's probably better to have it's own so it's independent from rc.local

Like rc.local is called by S99local usually in each rcX.d directory in /etc/rc.d
