One of GoldenGate 12.2 new features is replication support for MSSQL Standard Edition. In the previous GoldenGate 12.1 release, GoldenGate supported capture of DML only from SQL Server Enterprise Edition, due to the method of enabling Supplemental Logging, which is done via a feature only available to Enterprise Editions of SQL Server. Fortunately, beginning with Oracle GoldenGate 12.2, GoldenGate is able to enable Supplemental Logging for Standard Edition instances via a different mechanism. That mechanism to enable Supplemental Logging is done via certain SQL Server Replication components. These SQL Server Replication components are required to be installed and configured in order to enable Supplemental Logging,
Also it is very interesting that MSSQL doesn’t offer Change Data Capture for MSSQL Standard Edition. So if we have 100 offices with MSSQL and we need to collect only changed data to Data Warehouse then it is required to install MSSQL Enterprise Edition in every office because CDC is only available in MSSQL EE.
