How Do I Configure Source Database Information for a DDM DR Task?
DRS allows you to connect to the source database of a DDM DR task by entering an IP address, as shown in Figure 1. During DDM DR, DNs in the source and destination DDM instances have a one-to-one mapping relationship. You need to correctly enter the mapping between DNs in the source and destination DDM instances. For details about schemas and DNs in schemas for a DDM instance, see DDM product documentation.
Before creating a DDM DR task, you are advised to import the schema information of the source DDM instance to the destination DDM instance. For details, see Importing Schema Information.
On the DRS console, enter the DN information of the source DDM instance based on the DN mapping, that is, the RDS for MySQL information mounted to the DDM instance. For example, if the source DDM instance 1 has a DN and the IP address of mounted RDS for MySQL instance 1 is 192.168.1.10, and the destination DDM instance 2 has a DN and the IP address of mounted RDS for MySQL instance 2 is 192.168.6.150, set the parameters in Figure 1 to establish the DN mapping.
If a DDM instance has multiple DNs, ensure that each destination DN correctly corresponds to the source DN.
