Scenario 3: Create the Source and Target Configurations

Using DGMGRL, connect to the source container database boston using the wallet created in Scenario 2: Prepare the Environment and create the source configuration Boston. It must contain the source container database boston with PDBs bos_sales, bos_acct, and bos_finance. The source PDB that will be protected using a DG PDB configuration is bos_sales.

Using DGMGRL, connect to the target container database newyork using the wallet created in Scenario 2: Prepare the Environment and create the target configuration NewYork. It must contain the target container database newyork, which will provide data protection to the PDB bos_sales in the source configuration Boston. The source PDB bos_sales will be protected by the target PDB nyc_sales created in Scenario 6: Configure Data Guard Protection for the Source PDB.
