Oracle GoldenGate can read DB2 archive logs on tape, but it will degrade performance. For example, DB2 reserves taped archives for a single recovery task. Therefore, Extract would not be able to read an archive tape that is being used to recover a table until the recovery is finished. You could use DFHSM or an equivalent tools to move the archive logs in a seamless manner between online DASD storage and tape, but Extract will have to wait until the transfer is finished. Delays in Extract processing increase the latency between source and target data.
