The image shows the topology of the use case described above.

In the upper left is the source primary CDB (CDB100) containing 2 PDBs (PDB002, PDB003).

The lower left shows the standby CDB for CDB100 (CDB100_STBY) containing 2 PDBs (PDB002, PDB003).

An arrow from source primary CDB CDB100 pointing to its standby CDB100_STBY is labeled "Data Guard Redo Ship/Apply".

The upper right of the image shows the destination primary CDB (CDB200) containing one PDB (PDB001).

The lower right shows the destination standby CDB for CDB200 (CDB200_STBY) containing one PDB (PDB001.

An arrow from the destination standby CDB CDB200_STBY pointing to its primary CDB200 is labeled "Data Guard Redo Ship/Apply".

Between the source primary CDB (CDB100) and the destination primary CDB (CDB200) is shown an ASM disk group with solid lines to each primary CDB.

Between the source standby CDB (CDB100_STBY) and the destination standby CDB (CDB200_STBY) is shown an ASM disk group with solid lines to each standby CDB.
