< RAC Attack - Oracle Cluster Database at Home

  1. In the Inventory tab at the left, select collabn1.
  2. Choose the Console tab. Click on the play button to start the VM. When you see the square boxes, click anywhere to open a console window.

  3. Login as the oracle user with the password racattack.

  4. Open a terminal window.

  5. Switch to the root user with the "su -" command. (The password is racattack.) CONFIRM that two new disks exist and that they have the appropriate sizes. These two lines should exactly match!!

    [root@collabn1 ~]# cat /proc/partitions
    major minor  #blocks  name
       8    16    3407872 sdb
       8    32    3407872 sdc
  6. Create partitions on all of the newly created disks with fdisk.

    1. run fdisk /dev/sdb You should see the message "Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel"
    2. type "n" to create a new partition.
    3. type "p" for a primary partition.
    4. type partition number 1.
    5. press enter twice to accept the default first/last cylinders.
    6. type "t" to set the partition type.
    7. enter partition type da (Non-FS data).
    8. type "w" to write the partition table to disk.
    [root@collabn1 ~]# fdisk /dev/sdb
    Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
    Building a new DOS disklabel. Changes will remain in memory only,
    until you decide to write them. After that, of course, the previous
    content won't be recoverable.
