The cdr remaster command redefines an existing master replicate, or turns an existing non-master replicate into a master replicate. You must run the cdr remaster command if you add a new replicated column or drop a replicated column. If you modify a replicated column, you should remaster, however, remastering is not mandatory.
To use automatic remastering simply run the cdr remaster command for the replicate for which you want to update the definition.
To use automatic remastering, the master replicate definition must have been created with name verification turned on (--name option of the cdr define replicate command set to y). See Appendix A. Command-Line Utility Reference for details about the cdr remaster command and the cdr define replicate command.
You must use manual remastering if your participants to not have matching column names and they were created with name verification turned off (--name option of the cdr define replicate command set to n).
While performing the cdr swap shadow operation, Enterprise Replication stores the BEGIN WORK position of the last known transaction sent to the grouper as a swap log position for the current swap operation. Any transaction begun prior to the swap log position will use the original (old) replicate definition. Any transaction begun after the swap log position will use the new replicate definition.
The old replicate definition will be cleaned up automatically after the replicate definition is no longer required by Enterprise Replication.
