TUniLoader - Oracle 19c: Direct path loading is not supported in Direct mode

Hello,

we are currently using version 8.4.4 of the "Universal Data Access Components" for Delphi 10.4. For copying data we use the component TUniLoader, which has worked without any problems so far.

We now want to copy data from one Oracle 19c instance to another Oracle 19c instance. For both connections we use a DIRECT connection without the oracle client.

Here we get an error message with the following call:
  1. uniDest.LoadFromDataSet( qrySource);
The error message:
  1. Direct path loading is not supported in Direct mode
What are we doing wrong?
