good day everyone. I have downloaded the Wso2 DAS server for reporting purposes to make various dashboards. i successfully added my Oracle database to the datasources and the connection is healthy! however when i make an attempt to generate a gadget using the relational DB source its gives me the following error (Error! in database configuration). ive checked my DB url and its perfect , i have literally searched everything on google. i even tried using a batch data source but i fall flat on that attempt as well. please help me! am i missing a crucial step before adding a gadget or what?
Gadget generation in DAS 3.1.0 was not supported for oracle database. So this error is normal. All the issues with oracle and other major databases like DB2, PostgreSQL, MSSQL was fixed with this pull request. Since a release does not happen after this change, you can build a DAS pack locally and check.
Or you can do the following
Get the changed files from pull request.
Copy and replace these changed files with files in <DAS_HOME>/repository/deployment/server/jaggeryapps/portal/extensions/providers/rdbms
Now check gadget creation.

I am currently making an IoT device with an App. I had hired freelancers to make that App using Google Firestore since my IoT hardware is also connected to Firestore. The app was made using flutter and uses Firebase Authentication as well.
However, it has been suggested to me that AWS is a better solution for my IoT device, particularly because we were able to successfully connect our hardware to AWS, which was difficult for us to do using Cloud Firestore.
Now the challenge is: to change the App database. Since the project is at a nascent stage, our team can afford to use take some time to migrate from Firebase to AWS.
But my question is: how easy will it be for an app developer to change the database of an App that is partially made?
"Partially made" so I'm guessing the app is not in production. This reduces the difficulty.
Things that make migration hard.
Different types of database. If the aws database is not NoSQL (firestore is NoSQL), the difficulty is increased.
Data structure. Are the both data structures the same? if no, your developers will spend sometime transforming the data to the new structure.

I am trying to see if there is an easy way to setup my Oracle SQL Developer so that I can run everything though it but store data on my AWS account (free tier). I tried creating a RDS (which will likely expire after 12 months) database and used the endpoint + port to create a new database connection in SQL developer and even with the correct username/password it errors out the below message.
To be clear, I am trying to do what this guy did in his video but I am receiving an error. I think something might be wrong with my security group. The group type that he used is not an attribute of the current drop down options in there. I was thinking perhaps there is another way of doing it, such as a SSH or something of that nature.

Anyone have any good ideas?
No.
AWS Dynamo is not a relational DB...it does not understand SQL.

I have a webapp running with Django. I would like to make an Enterprise Edition of this website. In exchange for a yearly fee, I would like to allow companies to host the webapp on their own server and benefit from unique features
The problem is that I have no idea how to proceed. How can I execute this, without sending my whole code over to their computer and launching the django app there?
Is there something like generating an .exe that would run the django app without sending my code? How do companies usually proceed to make their tools available on another company's intranet?
well I haven't heard something like that, but what you can do is using a license in your code, there are many types of licenses, from open source to trade secret license, read more about it

How can I make our software's data available as an app in Power BI so our customers can choose to integrate their data in Power BI?
I know there is a Rest API and I have seem many samples of how to use this for internal software. However I don't want each customer to have to create an api application. I want our app to appear like Salesforce & Zendesk etc. do so the customer can simply pick us from the list.
Hope this makes sense.
I have helped a client of mine work through the process and it involves working with Microsoft to get the public content pack published. The process is outlined here. I would start by following the steps indicated there like filling out the nomination form and reaching out to support before you begin. There are a number of constraints around authentication and APIs and refresh you need to be aware of before you begin development and it is best to discuss this with support.

For example I want to make program , where people create user for them-selfs and saves some notes for that user . On my computer I have created database named noteapp , and two tables , users and notes . I think the details of code and table columns is not necessary in this question. In my computer this program works. I create one user for me and save notes in it . it goes to database noteapp. but if I will send this program to someone else , it will not work . what should I do ? the database is not one for all people . every computer must have it's own database named noteapp stored as file in computer. what i should do ? i dont know from what should I start. Some people didn't understand me and said that I must install mysql server on other computer to run this program . but it is not one other computer. It will be on hundreds of other computers. Like usual desktop programs that we download from internet . thank you
P.S.I work with visual studio 2010, mysql workbench 6.0. c++
If you need a local database engine for your app to run on the client, you could deploy an embedded database as part of your application.
If you've developed using MySQL, then it's probably easiest for you to use the MySQL embedded server library with your application.
Documented here: https://dev.mysql.com/doc/refman/5.5/en/libmysqld.html
MySQL isn't the only choice; there are lots of other embedded databases your application could use, such as SQL Server Compact (for the Windows environment), or SQLite (embedded in Google Android smartphones.)
