Allocating Journals to an Extract Group

One Extract process can process a single journal. If using more journals than that, use additional Extract processes to handle the extra journals. You can also use additional Extract processes to improve capture performance if necessary.

Note:

To ensure transaction integrity, all objects that correspond to any given transaction must be read by the same Extract group. For more information about using multiple Extract processes, see Tuning the Performance of Oracle GoldenGate in Administering Oracle GoldenGate.
