The rs_subcmp is an executable program that you can use to compare primary and replicate tables, optionally reconciling any differences found.
For non-Sybase database support, you may use rs_subcmp, provided you have connectivity to the primary and replicate databases. You must also develop custom SELECT commands for the primary and replicate databases to generate comparable outputs for both. Additional options are to buy third-party tools that provide such functionality, or build your own application.
