I have built SSIS packages to load data from one Oracle database to another before, but never had I come across this error until recently:
“ROW-00060: Internal error: [dainsert,16] Source: Oracle Destination: Oracle Error Occurred @ after 403k records.”
Initially, I thought that some constraint had been violated on the destination data source – like an attempt at a NULL value being inserted into a NOT NULL column. I ran the package a few times and noticed that the row count was always in the neighborhood of 400k and that the package had run for hours. I thought it odd that so many rows could be inserted with no problem, and so a double- and triple-checked to make certain that the constraints on the source columns were the same as those on the destination ones.
Though there were no clear cut solutions explaining exactly why this error happens, several different people on different fora mentioned that they had overcome this particular error (at different row counts, not always 400k!) by using a connector from Attunity rather than the one that comes with the Oracle Client. Fortunately, this driver is made to work with SSIS and is distributed by Microsoft. This driver not only works with Oracle, but also with Teradata. Choose the version based on the version of SSIS you are using.
Version 2.0 for SQL 2012
Version 3.0 for SQL 2014
Version 4.0 for SQL 2016
After installing the connector into Visual Studio and restarting VS, you should be able to use it by selecting “Oracle Source” and/or “Oracle Destination” from the SSIS Toolbox.
After setting up the new source and destination connections, I was able to run the SSIS package to completion, loading over five million rows of data in less than an hour!
