CPU mother board crashed


Hi,

I have RHEL3 installed on my machine, It is having lot of data and 2 databases oracle and mysql are running on it. Now my cpu is having problem and it is going to be replaced by the new one. Hard disk is fine.

Whether the new CPU will be able to boot with the old hard disk. If not is there any way so that i can recover everything with the old hard disk. SO that i need not have to install any packages and configuration seetings after the replacement.

Please suggest. How can my new cpu will be a mirror of the old one.

A CPU does not store any information in it. It has some memory, but it's like RAM - it's gone after a reboot. Installing OSes does not permanently change anything in the CPU.

thanks,

My question is, is it possible to restore the system with the hard disk. Nothing is left in the old system except hard disk . After replacing the CPU , whether my system will boot with the old hard disk?. Whether my old databases are still accessible? The thing is i dont have any backup of DB. I am having many softwares running on it like webmin etc. Whether i need to reinstall and configure those?

Usually you can move the hard disk to another computer,
and Linux will behave as nothing was changed.
( You may have to run 'redhat-config-network' ? ).

And from Intel CPU to AMD CPU : also OK.
Only one thing to say : try it.
( I have never done that with the old EL3, so no guaranties.)

Linux is very good about identifying new hardware and booting with it. You should have no trouble.

If it is just linux you shouldn't have any problems. But if you dual boot with windows, windows will see a different cpu (part of Bill Gate's anti-piracy stuff WGA) and get upset. You would have to call Bill and see if you could get your windows license reactivated.
