Installation
 

Hi Guys,
Can I check with you guys if installating software it will best to be in root or user mode? Otherwise if the a mixed between the two. Den what kind of software should install using root and what software should use user mode?

If i want to install Sun Java j2sdk and j2re should i install in root or in user?

But if i install software in root, how can i allow perimission for the usage of the software in user?

You can compile any software as user and even run it from your directory, usually, but to install any software, you have to be root unless you change things significantly and changing them that way isn't a good idea. The installation will usually take care of the permissions. If not, 'man chmod' and change the permissions.

so what abt the j2sdk or j2re?
are they significantly affecting the system?

I don't understand what you mean by significantly affecting the system. I don't guess they're as significant as upgrading your kernel or your c libraries. j2sdk is a Software Development Kit or something? Java programming? And jre is the runtime environment. So you're a java programmer? I'd just install them like any other programs - configure, make, su, make install, exit, run - or whatever the details are for the packages. Well, except that I wouldn't because I'm not a programmer. :)
