Capture performance is noticeably slower in Shareplex 6.0. The performance degradation is traced to capture parameter SP_OCT_OLOG_QUEUE_SIZE which in 6.0.0 is set to 100 (default). When this parameter is changed to 1000, it improves capture performance in 6.0 . For RAC, we need to adjust one more parameter called SP_OCT_OPS_QUEUE_SIZE which in 6.0 is set to 1000 (default). After increasing this parameter to 10000, it increased performance on RAC as well.
