System parameters let you control the behavior of IBM InfoSphere CDC. If your replication environment requires a particular configuration, then you can use system parameters to modify the behavior of default operations in IBM InfoSphere CDC. The default system parameter settings are appropriate for most installations. Maintain these default settings until you become familiar with the configuration of IBM InfoSphere CDC.

IBM InfoSphere CDC provides system parameters that control the behavior of your source and target datastores.

If you make changes to a system parameter during active replication, you must stop and restart replication for the changes to take effect.
