Data guard at PDB (pluggable database) level

One or more computer-readable non-transitory media storing instructions that, when executed by one or more processors, cause:

• receiving, for a first container database through a first network connection, redo data of a first instance of a first pluggable database in a second container database, wherein the first network connection is a network connection between the first container database and the second container database;
• applying, to a second instance of said first pluggable database in the first container database, the redo data of the first instance of the first pluggable database in the second container database;
• receiving, for the first container database through a second network connection, redo data of a first instance of a second pluggable database in a third container database, wherein the second network connection is a network connection between the first container database and the third container database;
• and
• applying, to a second instance of said second pluggable database in said first container database, while said second instance of said second pluggable database in said first container database is in service, the redo data of the first instance of said second pluggable database in the third container database.
