Connect node with Oracle - oracle

I need to connect to oracle db and fetch some data through node.
Is there any driver available to connect node with oracle? Is this possible?
Found many links to this question in stackoverflow, but none had the updated answers. Any idea? Please help.

I know this post is already few months old, but this one is the official Oracle driver for NodeJS:
https://github.com/oracle/node-oracledb
Link on npm:
https://www.npmjs.com/package/oracledb
I have used it for a few months now for simple cases and it works really fine.
Community is active so they are adding new features on a regular basis.

Whenever in doubt consult NPM. For oracle specific node module check oracle module
and db-oracle module

Not able to create connection on oracle sql developer tool

I'm trying to create a new connection on the Oracle SQL Developer tool but I'm not able to. I just simply download the latest version of oracle SQL developer tool from the oracle site and unzip the folder and run. I haven't set any password or anything because there is nothing to do so.
Please guide how I can make a local connection on oracle Sql developer tool.
Well based on what you have described, you only installed SQL Developer, without having the Oracle Client installed on your device.
To be able to connec to to something in SQL Developer, you need to have a database to which you would like to connect. That basically means that either you need to install one, or you have one available in your System. But I will assume that you are new to this and have no database to connect to.
First things first, you will need to install the Oracle Client. A pretty good example can be found on here. You have a video tutorial which contains a step by step guide.
Once you finished installing the Oracle Client, you can proceed with unlocking the basic HR Schema, or create your own DB Schema. Again, a tutorial on how to achieve this step can be found here.
There are a few steps to follow, but in the end, if you follow them accordingly, you will be able to make a local connection on oracle using SQL Developer. Besides that, both the links will provide you with some explanation as well for each particular task.

Getting following error while running oracle oracle apex 20.2 application-Forbidden The requested operation is not allowed

Forbidden
The requested operation is not allowed
I have created new application and getting above error while running app on local server
Old Question, but this might help others:
Seems like the friendly URL feature introduced in APEX 20.1 is causing this issue. A workaround for me is just disabling that in the Application Definition Atrributes.
I had the same problem after upgrading from Oracle Apex 19.2 to Oracle Apex 20.2. I tried everything and nothing happened. I found this:
https://docs.oracle.com/en/database/oracle/application-express/20.1/htmrn/index.html#HTMRN-GUID-175AC460-3BCB-4871-A14C-5A232EDF8CAD
I'm not sure if this is the case, but I can't find any other explanation - in section 2.1.1 Oracle Database Requirement it is said that version 20.2 is compatible with database version 11.2.0.4 and above. Mine is 11.2.0.3. Probably doesn't work for that. Check your version of the database and share if you are below the required one to know if I guess correctly. If so, and you want APEX 20.2, you may need to update your database version first, if a possible.
I hope I helped.

Steps to create dag in airflow by connecting to remote database

I am learning airflow and I have to create a dag that will connect to a remote oracle database and insert data from one table to another. Below is what I have done till now
After installation, ran pip install 'apache-airflow[oracle]' so that I can use oracle operator
Created connection string from UI to connect to remote database
Then I wrote my first dag but it didn't seem to run.
Before I try to find why it's not running, I want to make sure if I have to do some other steps that I may have skipped like some changes in airflow.cfg file especially in sql_alchemy_conn (this file I found in my home directory) or if cx_oracle is required to be installed so that I can connect to remote database or just connection string is needed (step 2 above).
There are so many things mentioned about airflow but yet not clear on the exact steps. If someone could help me in this that will be much appreciated. These might be the basics but I am stuck with what to do from end to end. Please help
Thank you!!

A database on apex.oracle.com is to be connected to airflow

I have database on apex.oracle.com and I want to make a connection to airflow.
This answer didnt help me: How to Connect Airflow to oracle database
How to find the sid of my database?
I googled after alot of search I found a answer. Which was giving an error.
I executed this
grant select on v_$sql to username;
This gives an error:
ORA-00933: SQL command not properly ended
Please help me in complete detail if possible.
What should be entered in host name? I don't have any hosting platform. Should database need to be deployed or hostname can be found for a database created on apex.oracle
As far as I can tell (which doesn't have to be correct), give up. Database on apex.oracle.com isn't accessible from the outer world. As stated,
This site (apex.oracle.com) is intended only for the customer
evaluation of Oracle Application Express.
so - you should use it to test your Apex skills and nothing more. If you need to use a database, download and install your own copy - it is available on the Oracle Technology Network, free for evaluation purposes.
Or, consider contacting one of database hosting companies, if you want to access it on the Internet.

OBIEE configuration

I have my current OBIEE installed in a linux server under oracle directory. Now the current warehouse (ODI and data storage ) has moved to AWS.Can I change any configuration file within this installation to point to the warehouse tables in AWS instead?
I know my articulation of the problem is bit confusing. I will be happy to clarify if needed.
Thanks
