Failed to save modifications to the server. Error returned: 'OLE DB or ODBC error: [DataSource.Error]

I am using the SSAS to develop the tabular model. I am able to extract the data from the database. However, when I try to deploy I keep on getting this error.
Failed to save modifications to the server. Error returned: 'OLE DB or ODBC error: [DataSource.Error] An error happened while reading data from the provider: 'Object reference not set to an instance of an object.'. '.
I have tried many solution like:
Check my database connection
Check the datatype in the table
However, none of the solution works.
Is there a way to find the issue with the Object reference not set to an instance of an object error?

Oracle Lob Operation FILEOPEN Failed I/O Error

I have an issues where my DBMS_LOB open operation which falls over where by I receive the following error message.
I have double checked the file exists, that the permission on the file are open to everyone one on the destination server, the database user has full access to the Oracle Directory.
I have seen similar issues where by it states that the file does not exist or the directory is invalid but I have not seen an I/O error before.
Any guidance is appreciated, I have been on the server where the file is located and I can't see what might be a miss based on the error message as the file definitely exists.
Oracle version is 11.2 trying to read from a windows server 2019.
Many Thanks,

SSIS project not working when reading from Oracle

I've been trying to create an SSIS project to read from an Oracle 11.x database to an SQL Server database.
When I set this up in Visual Studio 10 Shell, I do not receive any logs . It gives me a successful message but nothing happens.
I tried to connect to an Oracle 12c database and the same happened.
I tried to get data from an Oracle 11.x project and dump it into an excel file. I also tried to get data from an Oracle 11.x table and dump it into a new Oracle 11.x table (in the same database) and in both cases I got the following error:

Can anyone help me please?
Thank you
You haven't posted how you are trying to get data from oracle exactly so can say much about the error. I can only give my solution in 2008 r2:
create an oracle linked server in your sql server and then use an open query in the SSIS package to pull anything you need

How to increase Data flow task to handle more than 50 million records in SSIS

I am facing a challenge when I try to load more tha 6 million of records. I am getting the below exception after 3 million records.
The attempt to add a row to the Data Flow task buffer failed with error code 0xC0047020.
The input source is a text file and destination table is oracle. Do I have to do any configuration.

Data Flow Task Hangs forever

I am new to SSIS, I have developed a simple solution that takes data from a FLAT FILE SOURCE, does some data conversions and Inserts this data into a database table using OLEDB Destination Task.
My problem is it works fine on my test database, When I change the database connection, it gets stuck forever in the the Control Flow task and never gets into data flow task(The Data Flow Task continues to remain yellow instead of turning Green).
After around 30 minutes, it goes forward and gives me an error at OLEDB destination block saying "Out Of Memory" as shown below.
[OLE DB Destination [589]] Error: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x8007000E.
An OLE DB record is available. Source: "Microsoft Cursor Engine" Hresult: 0x8007000E Description: "Out of memory.".
[SSIS.Pipeline] Error: SSIS Error Code DTS_E_PROCESSINPUTFAILED. The ProcessInput method on component "OLE DB Destination" (589) failed with error code 0xC0202009 while processing input "OLE DB Destination Input" (602). The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running. There may be error messages posted before this with more information about the failure.
Please Help me with this.
