Which three activities are possible for PDBs? (Choose three.)
Which three activities are possible for PDBs? (Choose three.)
The correct activities for PDBs include converting an application seed to an application PDB, converting an application PDB to an application seed, and converting a regular PDB to an application PDB. An application seed serves as a template to create application PDBs quickly. It is possible to convert an application PDB (which is a fully functional PDB containing application-specific objects and data) back into an application seed to serve as a basis for creating more application PDBs. Additionally, it is feasible to convert a regular PDB, which operates independently within a multitenant database, into an application PDB that is part of an application container, thereby leveraging the shared data and metadata across different PDBs within the same application.
CDE sounds right.
C, D, E C, D Application seed can be created from CDB seed – Application seed is created unsynced with the application in application root Application root – Application seed is created synced with the application in application root but script pdb_to_apppdb.sql needs to be run Application PDB – Synchronization status of Application Seed created is same as the source application PDB Application PDBs can be created from CDB seed – Application PDB is created unsynced with the application in application root Application seed – Synchronization status of created Application PDB is same as the source application seed Application PDB – Synchronization status of created Application PDB is same as the source application PDB https://blog.toadworld.com/2017/07/10/oracle-multi-tenant-application-containers-part-ii-create-application-container E: http://oracle-help.com/oracle-database/multitenant/convert-regular-pdb-to-application-pdb/
CDE I believe C. converting an application seed to an application PDB TRUE, "An application seed enables you to create application PDBs quickly. It serves the same role within the application container as PDB$SEED serves within the CDB itself." D. converting an application PDB to an application seed Example 14-9 https://docs.oracle.com/en/database/oracle/oracle-database/21/multi/creating-application-seeds.html#GUID-640F2ABE-998E-4F12-871E-2250EC6A0463 E. converting a regular PDB to an application PDB Yes, possible and referenced in http://oracle-help.com/oracle-database/multitenant/convert-regular-pdb-to-application-pdb/
agreed CDE Not sure about converting application container F&G. Also, not sure convert back application PDB to applcation root or regular PDB
you can create app seed from app pdb "Example 14-9 Creating an Application Seed From an Application PDB": https://docs.oracle.com/en/database/oracle/oracle-database/21/multi/creating-application-seeds.html#GUID-640F2ABE-998E-4F12-871E-2250EC6A0463 for other answer: https://docs.oracle.com/en/database/oracle/oracle-database/21/multi/relocating-a-pdb.html#GUID-0A5C8EFF-51A4-497B-8D5C-A4267A694D4B
As far as I have been able to verify: having a PDB application seed, unplug application seed into <xml file>, drop application seed keep datafiles and create pdb application using the previous <xml file>, this works fine, so C must be true. The opposite way also worked: unplug application PDB into <xml file>, drop this application pluggable database keep datafiles and create pluggable database as seed using <xml file> works correctly, so D must be true and E is obviously correct. So, CDE seems to me to be the correct answer
I think AEF A: You can unplug an application pdb to be plugged in elsewhere F: https://docs.oracle.com/en/database/oracle/oracle-database/21/multi/relocating-a-pdb.html#GUID-0A5C8EFF-51A4-497B-8D5C-A4267A694D4B D: Nice example. You can also create a pdb$seed by cloning https://docs.oracle.com/en/database/oracle/oracle-database/19/multi/creating-removing-application-containers-seeds-with-sql-plus.html#GUID-93AAE6F0-7969-4D05-B10B-F2514CB39417
I think ADE
CDE, i agree
