error: can't create transaction lock [Fedora rpm installation]

A Small tip regarding rpm installtion of Fedora, whenever you are running rpm command to install any of the plug-ins or packages , you might run into transaction lock issue,

# rpm -ihv RealPlayer10GOLD.rpm
# error: can't create transaction lock

Above is nothing but Super User access problem, All you have to login as Super user (su), like following.

# su
# password:[XXXXXXXX] <------------This will be invisible
# rpm -ihv RealPlayer10GOLD.rpm
# Installation....

A Small tip, but helps a lot for beginers
