The image shows the topology of the use case described above.
In the upper left is the source primary CDB (CDB100) containing 2 PDBs (PDB001, PDB003).
The lower left shows the standby CDB for CDB100 (CDB100_STBY) containing 2 PDBs (PDB001, PDB003).
An arrow from source primary CDB CDB100 pointing to its standby CDB100_STBY is labeled "Data Guard Redo Ship/Apply".
The lower right of the image shows the destination primary CDB (CDB200) showing one PDB (PDB002) in the first PDB "socket" .
The upper right of the image shows the destination standby CDB (CDB200_STBY) showing one PDB (PDB002) in the first PDB "socket" .
An arrow from destination primary CDB200 pointing to its standby CDB200_STBY is labeled "Data Guard Redo Ship/Apply".
Between the source standby CDB (CDB100_STBY) and the destination primary CDB (CDB200) is shown an ASM disk group with solid lines to each CDB.
