Error on data

[fj40wdh]

When replicating data from Oracle to SQL Server we get this error, how can I find the source row that is causing the problem?

changed to Transactional apply and that fixed it.  Why?

Hello @fj40wdh ,

Thank you for reaching out to the Qlik community!

From the logs it appears that your batch is failing due to memory issue " Cannot allocate memory" Replicate will calculate memory based on the Max LOB size. Max LOB size* number of LOB columns * number of rows in that batch. The moment when you changed it from Batch optimized to "Transaction Apply" it went fine, As Transaction Apply works in one-by-one mode.
