Question: What is the transaction size and array size in OCI stage?how these can be used?

Answer: Transaction Size - This field exists for backward compatibility, but it is ignored for release 3.0 and later of the Plug-in. The transaction size for new jobs is now handled by Rows per transaction on the Transaction Handling tab on the Input page.

Rows per transaction - The number of rows written before a commit is executed for the transaction. The default value is 0, that is, all the rows are written before being committed to the data table.

Array Size - The number of rows written to or read from the database at a time. The default value is 1, that is, each row is written in a separate statement.
