### Remote connection information

oracle user
#sys and system users difference
Different 1> the importance of storing data
sys to store the data dictionary base tables and views, maintained by the database itself, any user can manually change, sys user owns dba, sysdba, sysoper other roles or privileges, is the highest authority oracle user.
The system users only store some level of internal data, such as management information oracle of some features or tools. For database management, System users have ordinary dba role permissions.
2> Different permissions
sysoper sys user with sysdba or system privileges, log em can only use these two identities, can not use normal.
system user can log on em with normal identity, unless you have it granted sysdba system privileges or syspoer system privileges.
#sysdba and sysoper difference between the two systems permissions
normal ordinary users
sysdba has the highest system privileges, log is sys
sysoper mainly used to start, shut down the database login user is public after sysoper
The difference #dba and sysdba
First understand the process of creating the next oracle service: Create an instance -> Start Instance -> Create Database
Startup process: Example start -> Load Database -> Open Database
sysdba is to manage the oracle instance, its existence does not depend on the entire database is fully activated, as long as the instance starts up, it already exists as sysdba login, load the database, open the database. Only the database is open, or the entire database completely after starting, dba role only exists foundation.
