How to re-index all resources in GREG 4.0.0

If you need to re-index all resources in greg 4.0.0, here I have explain how you can do that. 
This can be easily done by editing registry.xml located at CARBON_HOME/repository/conf folder. In registry.xml go to the indexingConfiguration section and then change the resource name of lastAccessTimeLocation to some other value.
Default value:


New Value (after changing the resource name):


Now restart the server, then greg will re-index all resources from scratch.

Reinstall grub2 after installing windows 7 (XP/Vista)

You may need to reinstall grub when windows is installed after ubuntu (or if you reinstalled windows in dual boot (Windows and ubuntu) system). I used following steps for reinstalling grub in order to login to my Ubuntu 10.04 after reinstalling Windows 7 on my machine.

1. boot the ubuntu LiveCD

2. Open a terminal and type
sudo fdisk -l

This list the partition tables, and in my case root (/) partition is on /dev/sda9.

3. Mount that partition using following command.

sudo mount /dev/sda9 /mnt

4. Run the grub-install command as below. This will reinstall the grub 2
sudo grub-install --root-directory=/mnt /dev/sda
Here "sda" is the hard disk on which your Linux distribution is installed!

5. Reboot

6. Finally Refresh the grub 2 menu using following command

sudo update-grub

Now everything should be fine :)
