Setup Port Forwarding to Make It Easy to Connect From Your Host You can then start up and run SQL Developer inside the image OR you can connect to the database running on the image using the copy of SQL Developer you installed on your host machine.
It will boot a copy of Oracle Linux, start your database, and all that jazz.

You download the image, you download and install Virtual Box (also FREE!), then you IMPORT the image you previously downloaded.
Some browser based labs you can step through to learn Oracle. SQL Developer installed and ready to connect. a database and listener running for you to connect to. 11gR2 Enterprise Edition copy of Oracle. The OTN lab runs on a A Virtual Box image which contains: Oracle Technology Network Developer Day: Hands-on Database Application Development Lab If you’re a student (or anyone else) with little to no experience with Oracle, then I recommend the third option. Download, import, and run our Developer Days Hands-on-Lab (FREE!). Buy a copy of Oracle and download, install, and create a database. No administrator, no database, no nothing. ORCL – that sounds promising! ORCL is the default SID when creating a new database with the Database Creation Assistant (DBCA). Then you don’t have to worry about the server names, database names, and the port numbers. If someone has given you a TNSNAMES.ORA file, or setup your machine to have access to a TNSNAMES file, then you can just switch to the ‘TNS’ connection type, and use the dropdown to select the database you want to connect to. This file contains a list of database connection details for folks to browse – kind of like an Oracle database phoneboook. They’ll often also setup the connection details for everyone via a ‘TNSNAMES.ORA’ file. Normally an administrator will setup and install Oracle, create the database, and configure the listener for everyone else to use. It’s not like installing Office/Access either – it requires services, environment setup, kernel tweaks, etc. It’s not analogous to downloading a mobile phone app and and using it 10 seconds later. Oracle is a very sophisticated piece of software. I know all of this sounds very complicated The default port is 1521, but 1522 is often pretty common. Each listener ‘listens’ on one or more ports, you need to know the port number for each connection. You can run a database without a listener and you can run a listener without a database, but you can’t connect to a database on a different server unless both that database and listener are up and running. The listener is a service that runs on the server and handles connections for the databases on that machine. Localhost is a network alias for 127.0.0.1 which is an IP address that maps to the ‘local’ machine, or the machine you are reading this blog post on. These default settings CAN work, but ONLY if you have installed Oracle Database Express Edition (XE). Basically you need to know the following: where is this database, what’s it called, and what port is the listener running on? The Default Connection properties in SQL Developer So you’re going to need to install Oracle and create a database, or connect to a database that is already up and running somewhere. Installing SQL Developer does not give you a database. You see this ‘Connection’ dialog, and… Where am I connecting to, and who as? You NEED a database Pl sql developer without tnsnames.ora upgrade#
If you’re running that copy of SQL Developer, please take a second to upgrade now, as it is WAY out of date.īut I’m here to talk to the folks that have downloaded SQL Developer and want to know what to do next. If you install Oracle database, it includes a copy of SQL Developer. You’ll need about 30 minutes to set everything up…and about 5 years to become proficient with Oracle 😉 Oracle Database come with SQL Developer but SQL Developer doesn’t include a database I’ll show you what you need to get up and going so you can finish your homework, teach yourself Oracle database, or get ready for that job interview. If you’re here because you downloaded a copy of Oracle SQL Developer and now you need help connecting to a database, then you’re in the right place.
