Per l'operazione di ridenominazione un PDB deve essere in modalità RESTRICTED:
SQL> alter pluggable database PDBWFM close immediate; Pluggable database altered. SQL> alter pluggable database PDBWFM open restricted; Pluggable database altered. SQL> select name, open_mode from v$pdbs; NAME OPEN_MODE RESTRICTED ------------------------------ ---------- ---------- PDB$SEED READ ONLY NO PDBWFM READ WRITE YES
Eseguire la ridenominazione e riavviare (CLOSE / OPEN) un PDB:
SQL> alter session set container = PDBWFM; Session altered. SQL> alter pluggable database PDBWFM rename global_name to PDBWFM01; Pluggable database altered. SQL> alter pluggable database PDBWFM01 close immediate; Pluggable database altered. SQL> alter pluggable database PDBWFM01 open; Pluggable database altered. SQL> show pdbs CON_ID CON_NAME OPEN MODE RESTRICTED ---------- ------------------------------ ---------- ---------- 2 PDB$SEED READ ONLY NO 3 PDBWFM01 READ WRITE NO
Le directory corrispondenti al PDB non vengono rinominate. Se si desidera spostare i file di dati in una nuova directory, utilizzare la funzione "Sposta file di dati online" in Oracle 12c.
Per rinominare Oracle Managed-Files (OMF) consultare la documentazione disponibile nel riferimento di questo articolo [1].
