Hello! I'm fairly new to working with Oracle databases and I am learning by playing around with the Virtual Box and preloaded VM from http://www.oracle.com/technetwork/database/enterprise-edition/databaseappdev-vm-161299.html. That said, I'm trying to accomplish something I initially thought would be very simple: I want to get into the linux shell, type in "sqlplus / as sysdba" as the linux OS oracle user, and then log into the Oracle database that was provided. However, when I do this, it simply says:
ERROR:
ORA-01017: invalid username/password; logon denied
Yet for as much research as I have done, I can't seem to find the answer. I have made sure that oracle is in the dba group and the environment is already set up for ". oraenv" (after all, this is a prebuilt machine). I am able to connect to the database as system with the password "oracle" without any issues, and I can also connect through Linux with limited access if I type in "sqlplus", then enter the username and password for system.
What am I doing wrong here? Why can't I access the database as oracle through linux SQLPLUS? I would appreciate any help!
