oracle-First Knowledge

I've never used Oracle. Today finally installed, said I installed the process, feeling still a little toss.

One, I installed the Oracle version 9, the total size downloaded from the Internet 1.3G. is a three compressed package.

First, after extracting three compressed packages, I use UltraISO to convert three compressed packages into three iOS files.

Second, then I installed daemon Tools Lite, virtual three discs, three iOS files were loaded into the virtual CD.

Third, after running the first virtual disc, the Installation Wizard will appear, follow the prompts, the installation process will let you import other virtual disc files, and finally set the SYS and system and Scott three users password.

Unlike MSSQLSERVER, Oracle is an instance of a database, and there are many databases in an instance of MSSQLSERVER.

Oracle User side:

SYS user is superuser, has the highest privileges, has the SYSDBA role, has the CREATE DATABASE permission, the default password is the manager

The system user is an administrator, and as with the SYS permission, only the CREATE database is not available, the default password is Change_on_install
