| Summary | 0003587: Noorder sequence for performance on Oracle RAC | ||||
| Description | Oracle RAC must coordinate an ordered sequence (for sym_data) across the cluster, which results in wait time overhead for high throughput change capture. A "noorder" sequence reduces the overhead and is 30x faster. Add a oracle.sequence.noorder parameter that can be enabled for better performance on Oracle RAC. It will alter the sym_data sequence to be "noorder", add an index to sym_data for (create_time, data_id), and query sym_data with an order by of create_time and data_id. | ||||
