Hi All

I am using Redhat Linux4.5 & oracle 10g Dba suddenly powergone & my OS is crashed. I have huge data on this.

After rebooting the server last message is :
INIT:No more processes left in this runlevel

How to recover OS now. Please its very urgent for me

Looks like some kind of corruption of the data. I would start with the installation CD in "rescue" mode by typing "rescue" instead of hitting enter.

After that, avoid to mount the operating system, and then, fun fsck on all partitions or logical volumes.

Shalom,

The OS ext3 journaled file system will likely let you come back up without major data loss.

You should boot with a rescue disk and see if you can access and back up the oracle data.

You can boot to single user mode and use fsck.ext3 to check and correct all the file systems involved.

The data is probably fine. Oracle will come up once the OS does.

Hello Muralikrishna,
please try to recover os through fsck as Ivan & steven has suggested, if can not recover then you can re-image and do not make any changes to your data partition, just format /root partition, yes if you choose to do re-image you need to install all your application again, thanks,

Hi,
Guys, According to my experiance what i can tell it this shows a messed-up init scripts.

Better to know how this happened...

Some time back i ran in to this kind a issue and had to re-install init scripts from install media on rescue environment. The system worked fine after that.
But im not a Oracle guru so i cant comment about that.
I suggest you try this as your last option.

Good Luck...!
