Problems after removing glibc-* RedHat EL5

Question

ohh, I thinh I have done something wrong.
I did make a update from glibc-2.5-18 to ver glibc-2.5-34 but still got database restarting so I decided to remove glibc-2.5-34 for installing glibc-2.5-24.
I execute command:
root@DB1 ~# rpm -e nodeps allmatches glibc-2.5-34
warning: /etc/localtime saved as /etc/localtime.rpmsave
Invalid link from "ld-linux.so.2" to "/lib/ld-lsb.so.3": No such file or directory
error: %postun(glibc-2.5-34.x86_64) scriptlet failed, exit status 255
Now I can not do anything! I totally messed up in server :(
root@DB1 ~# yum install glibc-*
bash: /usr/bin/yum: /usr/bin/python: bad interpreter: No such file or directory
Somebody can me to fix that?

Ok, Matosh. Everything is now clear.
Note however that if you don't have a static rpm binary executable on your CD, you cannot do anything. Because when booting in rescue mode, rpm from the 1st installation CD is in memory, but it works only before you `chroot /mnt/sysimage', and at this "raw stage" (no environment) you cannot install anything with that rpm, unless the package is relocatable and can be relocated to the /mnt/sysimage/usr, instead of /usr that doesn't exist and its creation doesn't solve anything. But I doubt that glibc is relocatable. On the other side, after chroot, you cannot run that rpm from memory anymore. You depend on your root environment which is damaged. So, do exactly the following:
1. Find somewhere statically linked rpm executable and save/burn it on a CD. I can recall that Mandrake distribution used to have such a binary named rpmb, or rpmbig, rpmstatic or so. Let's say that you found out it and have it on CD under name `rpmstatic'.
2. Boot the system with the 1st installation CD and type `linux rescue'. Choose the language and keyboard, on the Setup Networking screen press No, on the Rescue screen press Continue. If this succeeded, the final Rescue screen will appear showing that the system has been mounted under /mnt/sysimage. Press OK to get a shell. Open a new shell console by Ctrl-Alt-F2.
3. Insert the CD with static rpm into a free CD/DVD drive. If you have only one, remove the install CD. If it is mounted, just unmount it by `umount /dev/hda'. It can be hda, hdb, sda, sdb or so. You must know that. Let's say it is /dev/hda. Then issue the folowing commands in this order
# mkdir /temporary
# mount -t iso9660 /dev/hda /temporary
# cp /temporary/rpmstatic /mnt/sysimage/bin/rpmstatic
# chroot /mnt/sysimage
# /bin/rpmstatic -ivh <path_to_glibc_package.rpm> /* you said you had it on HDD */4. Type `exit' and then `umount /temporary'
5. Remove CD and restart the system: Ctrl-Alt-Del
Hope this helps.
