title: Oracle 11g default username and password to start sqlplus
body: <p>I have installed Oracle 11g (latest version 11.2.0.1.0) on my system(Linux). During the installation, it didn't ask me to set a username or any password. I'm unable to start sqlplus because I don't have the username and password.
  Can anyone tell me what is the default username and password or what is the default password for SYS or SYSTEM?</p>
  
  <p>I have referred this "<a href="https://stackoverflow.com/questions/8722302/what-username-password-should-be-entered-when-connecting-to-sqlplus-after-ins">What username &amp; password should be entered when connecting to SQL*Plus after installing Oracle 11g?</a>" but my problem is not resolved.</p>
