This lesson develops Create, Clone, Relocate, and Refresh PDBs within Oracle Database 19c: Multitenant Architecture.
The work is anchored to a database team consolidating application databases into a governed Oracle 19c multitenant estate, so each decision is connected to a measurable operational result and an accountable owner.
The instructor traces create from seed, unplug/plug, XML manifests, compatibility, and file placement, then connects it to hot clone, refreshable clone, snapshot copy, sparse copy, and storage dependencies. The demonstration captures the exact configuration, transaction, command, query, log, or screen evidence needed to prove intended behavior and the applicable control boundary.
Learners execute a guided lab focused on hot clone, refreshable clone, snapshot copy, sparse copy, and storage dependencies and PDB relocation, availability, service movement, rollback, and network prerequisites. The exercise introduces a realistic exception related to provisioning errors, name conflicts, violations, and post-clone verification and requires a reversible correction supported by before-and-after evidence.
Acceptance requires accurate handling of PDB relocation, availability, service movement, rollback, and network prerequisites, traceable proof for create from seed, unplug/plug, XML manifests, compatibility, and file placement, and a repeatable recovery path for provisioning errors, name conflicts, violations, and post-clone verification. Results must be understandable to both implementers and operational support teams.
Learners compare symptoms, logs, state, dependencies, and recent changes when provisioning errors, name conflicts, violations, and post-clone verification occurs. The final diagnosis must separate the immediate fix from the preventive control.
The completed output is a tested create, clone, relocate, and refresh pdbs implementation or analysis, with validation evidence, troubleshooting notes, rollback guidance, and a concise operational handover.
