Oracle Database 12c: Active Duplication con RMAN (Caso 6)
Por Joel Perez , Mahir M. Quluzade (OCE) & Sebastián D'Alessandro (OCE)
Publicado en Mayo 2015
Índice:
- Introducción
- Caso 1: Duplicando CDB - Usando Backup Sets para ejecutar una "Active Database Duplication"
- Caso 2: Duplicando CDB - Usando Backup Sets comprimidos para ejecutar una "Active Database Duplication"
- Caso 3: Duplicando CDB - Creando Backup Sets en paralelo durante una "Active Database Duplication"
- Caso 4: Duplicando CDB - "Push-Based Active Database Duplication" de una CDB
- Caso 5: Duplicando PDBs - Duplication de una sola "Pluggable Database"
- Caso 6: Duplicando PDBs - Duplicación de dos "Pluggable Databases"
- Caso 7: Duplicando PDBs - Duplicación de dos "Pluggable Databases" omitiendo una PDB
- Caso 8: Duplicando PDBs - Duplicación los tablespaces de una PDB
- Caso 9: Duplicando PDBs – Duplicación al mismo tiempo de una PDB y un tablespaces en otra PDB
- Caso10: Duplicando PDBs - Duplicación de una CDB omitiendo tablespaces de una PDB
Veamos el sexto ejemplo para duplicar una base de datos con RMAN en modo activo.
Antes de continuar con la lectura le aconsejamos leer la (parte I) de esta serie para poder estar seguro de comprender la teoría relacionada con estos artículos. Si preparó su host destino como se indica en los 7 pasos descritos en la (parte 1), entonces podrá duplicar la base de datos utilizando RMAN.
Caso 6: Duplicando PDBs – “Pull-Based active Database Duplication” de dos “Pluggable Databases”
En el siguiente ejemplo estamos trabajando inicialmente como base de datos origen con la CDB llamada “prmcdb” que será duplicada en la CDB llamada “dupcdb” como ocurre también en otras partes de esta serie de artículos. Antes de la duplicación, vamos a sumar una nueva PDB: prmpdb03 a la CDB prmcdb clonando la PDB prmpdb02.

PDB$SEED READ ONLY
PRMPDB01 READ WRITE
PRMPDB02 READ WRITE
PRMPDB03 READ WRITE
En el host destino oel62-ora12c-dup creamos manualmente el directorio para la nueva PDB duplicada (prmpdb03). Esto es necesario porque RMAN no puede crear el directorio de manera automática al duplicar la “Pluggable Database”.
[oracle@oel62-ora12c-dup ~]$ cd $ORACLE_BASE/oradata/dupcdb
[oracle@oel62-ora12c-dup dupcdb]$ mkdir prmpdb03
[oracle@oel62-ora12c-dup dupcdb]$ ls -l
total 16
drwxr-xr-x 2 oracle oinstall 4096 Apr 14 09:10 pdbseed
drwxr-xr-x 2 oracle oinstall 4096 Apr 14 09:10 prmpdb01
drwxr-xr-x 2 oracle oinstall 4096 Apr 14 09:10 prmpdb02
drwxr-xr-x 2 oracle oinstall 4096 Apr 14 09:46 prmpdb03
[oracle@oel62-ora12c-dup dupcdb]$
Para este caso usamos el comando duplicate de RMAN con las siguientes opciones:
Opción de duplicación | Pluggable Databases – prmpdb01, prmpdb03 |
Tipo de duplicación | Active Database Duplication |
Método de duplicación | Pull-Based |
Tipo de backup utilizado | BACKUPSETS (default) |
Número de “Target Channels” | 1 (default) |
Número de “Auxiliary Channels” | 1 (default) |
El comando duplicate de RMAN en este caso quedará de la siguiente manera:
duplicate database to dupcdb pluggable database prmpdb01,prmpdb03
from active database
spfile
parameter_value_convert='prmcdb','dupcdb'
set db_file_name_convert='prmcdb','dupcdb'
set log_file_name_convert='prmcdb','dupcdb';
Descripción del código:
Como puede verse en el código, RMAN duplicará las “pluggable databases” prmpdb01, prmpdb03. RMAN duplica la lista especificada de PDBs delimitada con comas y pasa por alto las otras PDBs no especificadas (prmpdb02). Los canales “target” y “auxiliary” no son asignados de manera explícita en este código. RMAN asigna solamente un channel default para target y otro para auxiliary (ORA_ DISK_1 and ORA_AUX_DISK_1). La cantidad de target y auxiliary channels es la misma, esto significa que en este caso RMAN utilizara el método “Pull-Based” para la duplicación. También utilizamos para este caso los parámetros parameter_value_convert y db{log}_file_name_convert en el comando duplicate. El uso de estos parámetros está explicado en la primera parte (parte 1) de esta serie de artículos.
En la salida podemos observar un procedimiento normal de duplicación como siempre fue en versiones anteriores.
Veamos este código en acción:
