Oracle 11g Sys,system,scott Password not set up a workaround

Starting today with Oracle's powerful database, it has not yet experienced its powerful capabilities. Before I heard that the Oracle installation is very complex, and I just really installed a time later only to know, in fact, the default can be, of course, the speed will be very slow, my I3 processor also compared to the force, 20 minutes less than the fix, my version is 11g 11.12.0. Of course, all the way to the default is not wise, installed to run up to find, password settings that a jump past, but also did not save the default password document, found on the internet a lot of solutions are not done, in a senior inadvertently reminded, found the solution, as follows:

You can use Sql>sqlplus/as when you log in SYSDBA

will prompt you to output the password, the direct return, you find unexpectedly can log in, as for this sqlplus level younger brother temporarily still do not know, next sql>alter user sys identified by admin (this you arbitrarily set); After execution you find the hint: the user has changed

This means that your sys password has been changed to admin, you can sql>conn sys/admin as sysdba after you know the password of sys, you are the boss, you can change the password of system and Scott, In fact, Scott's default password is Tiger, can be used directly, but the first login will prompt you to modify, if you are turned into a test with this is also very good.

The summary process is as follows:
