Last semester we have a DBMS lab in our course. So we need to install oracle software to work with sqlplus. Installing oracle is easy, but it is not the same as installing other application software. If  something went wrong in installing oracle software, then you cannot easily re-install the same oracle software again without formatting. But you can uninstall oracle completely and re-install fresh copy of oracle software without formatting your PC.

In this post I’m going to install oracle 11g on windows 7 64bit PC. The same procedure you can follow to install on other windows OS like XP, Vista 32/64bit PC.

1.In Oracle 11g folder click on the setup icon. After that you will see the window like as show below. In Installation Type: choose Enterprise Edition (2.9GB). In   Database Password: and Confirm Password: field. Fill those field with tiger and click Install button.
