A download from a large Oracle table has taken significantly longer than normal. It is currently utilizing Attunity driver. A network trace was performed recently and it was noted the Oracle server is sending 4 packets but SQL Server is sending an ACK for every 2 packets.
Could this cause the longer transfer time? Network packet size on SQL Server is set to 4k. In SSIS batch size for Oracle Source is set to 10000. Increasing the batch size does not improve the transfer.
Thoughts?
