Connect JDeveloper application to Oracle Live SQL - oracle

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.

Oracle Apex application and database

Can I run Oracle Apex application on window's server and connected database to linux server?
More info,
I want to run my oracle apex application on windows platform, and i want to have conected database on exadata on linux server. Is it possible to have the network connectivity?
If no, please share the documentation.
Searched everywhere, and ask oracle DBAs
Oracle APEX runs in the database, but you usually connect to it through Oracle REST Data Services (ORDS) that can run standalone where you have Java, or deployed in Tomcat, including Windows. You will access and develop the APEX application with a browser on Windows, or any other place where you have a browser.
Have a look at chapter three in the installation manual for APEX

On Prem to Cloud with Data Factory

I have one On Prem Oracle database and one Azure SQL Database and want to use a Copy Data activity to transfer this data.
I have now created a Self Hosted IR for the Oracle database, and I am able to connect to it and preview data from Data Factory editor:
I have a Azure SQL Database that I want to recieve data, and it is set up with AutoResolveIntegrationRuntime, with Connection successful. I am also able to preview data from this database:
When I try to run this Copy Data activity I get following error message:
ErrorCode=SqlFailedToConnect,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=Cannot connect to SQL Database: 'sqlsrv', Database: 'database', User: 'user'. Check the linked service configuration is correct, and make sure the SQL Database firewall allows the integration runtime to access.
Based on all Docs/Tutorials I have read this should not be failing. I have tried to open up the SQL Server to allow all IP adresses in firewall rules.
Any ideas what I might be doing wrong here?
Since the integration runtime is a bridge across on prem and cloud , you need to check whether you are able to access the onprem database and the Azure SQL database through the VM in which the IR is installed.
The VM hosting the IR should be able to access both the source and sink for the copy activity to be successful in case if either of source or sink is using the self hosted runtime.
So the issue is not w.r.t Azure SQL database but in the VM hosting the IR

Error when adding Oracle DB to ODBC connection

Hi everyone here,
I am pretty new to Oracle DB configurations as I have been using SAS and Microsoft SQL all this while.
What i want to do is to add Oracle DB to ODBC(64-bit) in a new server.
This is the scenario:
Server A:- Existing Application server that has Oracle configured in ODBC(64-bit)(Been using for the past 3 years, configured by other people).
Server DB:- The Database server
Server B:- Brand new server that i want to configure Oracle DB in ODBC(64-bit)(Brand new).
I copy every single details of the server information in Server A ODBC for the same Oracle DB and put it in Server B ODBC. I have both Server A and Server B remote connection side by side and do "Test Connection".
Server A can connect successfully. However, Server B is giving me this error:
SQLState=08004
This is my first time trying to configure for ODBC to Oracle DB. I have previously configured many Microsoft SQL DB without any issue. Do take note that i have not installed any Oracle driver or any necessary-tool needed for ODBC to link with Oracle as i do not know of any. Is there anything i have to install for this to work or any necessary settings need to be done before configuring it?
All this while for Microsoft SQL connection to ODBC, i just put in the DB credentials and voila.
Your help is very much appreciated.

Is Oracle Instant Client an actual database?

I want to create a small dev database just to use for developing my application. I've downloaded the Oracle Instant client and followed the directions to "install" (ie, copy/paste and set up some environment variables), but I can't find any information on how to connect, login, create database, etc, or even exactly what Instant Client is, specifically. So, a few specific questions:
Is Instant client just a set of drivers and components that allow you to connect to an existing database, or can you use Instant Client to create and administer a completely new database?
If it CAN be used to create a new database:
How do you "start" (or similar concept) the database so that it is ready for connections.
Because there is no installation, and no default configuration, I haven't set up a default schema, port, etc. So, what is the default connection information to connect to the database for the first time?
For example, I use SQL Developer to connect to and administer my remote database, so how could I connect to Instant Client from SQL Developer?
The client is JUST a client.
You'll want to download the Oracle Database installs. The easiest would be the XE (Express Edition) - it's free, and gets going on windows or linux pretty quick.
You'll then install the server software and THEN create a database. Then you can use your client to connect to said database. You can use your client now to connect to any Oracle database running on any server that you can see on your network.
There are more alternatives.
I talk about this in more detail here.

How to connect to external oracle database from BSD

One of my work mates has set up a freenas server for storage (version9.1)
I have created a jail under this running FreeBSD 10.3-STABLE.
I want to create a web server in this jail and need to be able to connect to an external oracle (11g) database. I have the web server working but have been unable to find information on how to connect to an external oracle server from freebsd.
Is this even possible?
I am very new to BSD and Oracle.
The Ports collection contains several oracle clients/odbc drivers etc. in the databases category
