oracle 11g Personal Edition: Create Schema - oracle

This is a two-part question. I have installed an Oracle 11g Personal Edition Server on a Windows Server 2008 VM. During the installation I chose the option to install a database as well (sample/blank database?).
Now, on the VM, I can launch the Oracle Enterprise Manager Console at localhost port 1158, login as either SYSMAN or SYSTEM and in that I can see: 'Database Instance': orcl.127.55.199 . I can also see 'OracleOraDb11g_home1TNSListener' in the Services control panel in running state.
1) I need to be able to create a new Schema in the default database. How do I do that using the Oracle Enterprise Manager or anything else?
2) How can connect to that schema from another computer, say a Windows 7 workstation? I am able to see the VM running the Oracle server and I am even able to make a connection but I get an error like '12541 no listener'. I am pretty sure I have the Oracle client software installed. Do I need to create a TNS file? I am using Direct Connection.
Thanks!

Never mind:
I got this all to work. Here are some brief notes:
1) Used Oracle Database Configuration Assistant (ODCA) to create a database
2) Used Oracle NET Manager to Create a Listener
3) Restarted Oracle Listener Service
4) Used Oracle Enterprise Manager in localhost environment to create Users--which seem to be the same as Schema--thanks #Leo for your input in the Comments!
Everything works now!
Hope this helps someone.

Connect JDeveloper application to Oracle Live SQL

I am new to ADF/JDeveloper. I'd like to configure my ADF Web application to Oracle Live Server, since I'm using a Mac computer, which are not supported by Oracle's database distribution, I have tried to use Oracle VM but it freezes my Mac.
Needs information on database configuration panel are:
Host name
JDBBC port
SID
Oracle does not provide database connection information for the database behind livesql.oracle.com. If you want your own cloud database, you should look into setting up an Oracle Cloud Free Tier database. If you configure your database using the Always Free options, you should be able to have your database around for free forever.

Connect and create a local Oracle database

I've installed sqlplus64 throw this tutorial: http://webikon.com/cases/installing-oracle-sql-plus-client-on-ubuntu
I want to practice SQL using sqlplus (I can't connect remotely to school ssh).
I've tried everything I found in google and still can't connect.
I don't have any credentials
sqlplus64 / as sysdba
ERROR:
ORA-12545: Connect failed because target host or object does not exist
Welcome!
Probably the easiest way to get started with SQL using sqlplus is to use the virtual machine image Oracle provides for the hands on lab. It contains not only sqlplus, but a full Oracle 12c database, already configured correctly.
Download and instructions here. It's free. You'll need a free account on OTN (Oracle Technology Network), but that's necessary anyway to read the documentation about SQL*Plus and all the rest of it.

Cant create local connections in SQL Developer [duplicate]

I am new to Programming. I am learning JAVA and for DB i wanted to learn Oracle so I downloaded sqldeveloper from Oracle website. It was a zip file so I didnot have to install anything, simply extracted it. When I open the sqldeveloper and try to make a new connection, it shows error.
Test failed: IO Error: The network adapter could not establish the connection.
I am not sure what to put in username and pwd. and i am also not sure if i have to connect this to jdk or jre or set classpath for database.
Can anyone help me?? I have uploaded the snapshot of the error too.
You downloaded a client.
You did NOT download the server component though - the actual database.
SQL Developer just allows you to work with an existing database.
No worries, you're not that far away. You have several options.
Oracle Database Express Edition (XE) - it's completely free.
We also have a VirtualBox appliance you can use for personal learning purposes, also completely free.
I talk about this and give step by step instructions here.
Check if oracle service, TNSListener service is up and running before trying to make any new connection from sql developer.
Even if TNS Service is down , connection can not be established with oracle instance.

How to create local connection in SQL Developer

I only have SQL Developer installed. What other programs do I need to install to create a local database. Please provide links.
SQL Developer is a client that access to a database server to extract data.
You need a database server.
If you operate with SQLDeveloper probably you like to install Oracle. There is a simplified version of Oracle that is called Oracle-XE. Search it over google and download the right version for your operating system.
Give the username and password of the user you created. You can specify localhost in Host name. If you haven't modified the port on which Oracle works then give 1521. If you haven't changed SID as well then give XE. You might be able to connect with DB.
