Oracle Database 12c: Active Duplication con RMAN (Caso 10)

Por Joel Perez , Mahir M. Quluzade (OCE) & Sebastián D'Alessandro (OCE)
Publicado en Mayo 2015

Índice:

Veamos el décimo 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 que pueda 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.

Caso10: Duplicando PDBs - Duplicación de una CDB omitiendo tablespaces de una PDB

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 en otra parte de esta serie de artículo. A continuación podemos ver nuestra base de datos CDB origen:  prmcdb.

[oracle@oel62-ora12c-prm ~]$ export ORACLE_SID=prmcdb

Como puede observarse en la salida,  nuestra CDB origen (prmcdb) tiene dos PDBs:  prmpdb01 and prmpdb02. También, tiene creados  los tablespaces PDB01_TBS1, PDB01_TBS2 en la PDB prmpdb01 y los tablespaces PDB02_TBS1, PDB02_TBS2  en  la PDB prmpdb02. Si usted no ha creado esos tablespaces en las PDBs, puede utilizar los scripts de creación del caso 8 en la parte IX de esta serie de artículos.

En este caso duplicamos la PDB prmpdb01 y el tablespace PDB02_TBS2 del PDB prmpdb02 . Usamos el comando duplicate de RMAN con las siguientes opciones:


Opción de duplicación

Skip Tablespace - skip tablespace prmpdb01:pdb01_tbs2 

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 skip tablespace prmpdb01:pdb01_tbs2 
 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  la PDB prmpdb01  ignorando el tablespace PDB01_TBS2. Con este comando duplicate, RMAN duplica todos las PDBs incluida prmpdb01 , pero ignora el tablespace PDB01_TBS02 de la  PDB prmpdb01 . 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:

Podemos verificar la PDB duplicada y el tablespace en la CDB duplicada:

[oracle@oel62-ora12c-dup ~]$ export ORACLE_SID=dupcdb
[oracle@oel62-ora12c-dup ~]$ sqlplus / as sysdba
 
SQL> select con_id, tablespace_name from cdb_tablespaces order by  1,2;
 
  CON_ID TABLESPACE_NAME
-------- ------------------------------
       1 SYSAUX
       1 SYSTEM
       1 TEMP
       1 UNDOTBS1
       1 USERS
       2 SYSAUX
       2 SYSTEM
       2 TEMP
       3 PDB01_TBS1
       3 SYSAUX
       3 SYSTEM
 
  CON_ID TABLESPACE_NAME

       3 TEMP
       3 USERS

       4 TEMP

       5 SYSTEM
       5 TEMP
 
  CON_ID TABLESPACE_NAME
-------- ------------------------------
       5 USERS
 
23 rows selected.

 

Como podemos ver en la salida, todas las pluggable databases fueron duplicadas con todos los tablespaces, solamente fue ignorado el tablespace PDB01_TBS02 de la PDB prmpdb01.


Esperamos que esta serie de artículos haya resultado de utilidad.
