The shared memory feature of the UNIX operating system is required by Oracle. The System Global Area (SGA) resides in shared memory; therefore, shared memory must be available to each Oracle process to address the entire SGA.
Definitions of Shared Memory and Semaphore Parameters
SHMMAX = The maximum size(in bytes) of a single shared memory segment.
SHMMIN = The minimum size(in bytes) of a single shared memory segment.
SHMMNI = The number of shared memory identifiers.
SHMSEG = The maximum number of shared memory segments that can be attached by a process.
SEMMNS = The number of semaphores in the system.
SEMMNI = The number of semaphore set identifiers in the system; determines the number of semaphore sets that can be created at any one time.
SEMMSL = The maximum number of sempahores that can be in one semaphore set. It should be same size as maximum number of Oracle processes (The PROCESSES parameter in the init.ora file).

who or w or finger

Finger was a way to get information about a user from another system.

Who is used when you are on a machine to see who else is on the machine.

Finger is pretty old. For instance, many times “finger” will only show users connected by telnet.

But “who” will often show connections by telnet, ssh, rlogin, and even ftp connections.

Put the USB Drive into the Linux system and do the following from root user
# fdisk -l

Now you can see the new device which is not in /etc/fstab. May be like /dev/sda1

Then now we have to mount the device using following command
# mount /dev/hdb1 /mnt
Now the USB drive is mounted /mnt folder
# cd mnt
# ls
Note: If GUI System Adiminstration packages are installed and machine is running init 5 then it will automatically detect
