rs_subcmp utility allows you to compare primary and replicate tables in Adaptive Server databases, and reconcile any differences. Sybase provides the rs_subcmp executable program with Replication Server.
Some other database vendors may provide a similar “compare” utility that can perform the same function for their own databases, but there is no equivalent utility to support different types of non-ASE data servers (for example, to compare tables in an Oracle database to tables in a Microsoft SQL Server database).
For non-ASE database support, you can either acquire third-party tools that provide such functionality, or build your own application.
