Changing an user password using alter on ORACLE

Well , this is a simple command , so there is not much to be said about it , basically you need to go into SQLPLUS , to do this:

cd into $ORACLE_HOME , then cd into directory bin , on directory bin run:

./sqlplus /nolog

then type: connect / as sysdba

then run the alter command referring to the user you want to change the password to:

alter user sys identified by new_password;

In this case you can replace sys with the user you want to change the password to , and new_password to whatever secret you want to use.

Hope it helps
