Migración a la versión 12c de la base de datos Oracle sin interrupción de servicio usando Oracle Golden Gate 12c

Por Deiby Gómez Robles , Yenugula Venkata RaviKumar (OCM) y Nassyam Basha (OCP)
Publicado en Abril 2014

La interrupción del servicio durante una migración de versión de una  base de datos es una de las principales razones que influye en la decisión de realizar la migración o seguir manteniendo la misma versión aunque se tenga que hacer frente a los problemas que ya bien se conocen, como la falta de soporte del proveedor, la reparación de fallas y la falta de las nuevas características con que cuentan las nuevas versiones de bases de datos.

Utilizar “Oracle Golden Gate” para realizar la migración es la forma más simple y efectiva para reducir el tiempo de interrupción del servicio durante una migración de versión de una base de datos.
Durante la migración, no se afectará el rendimiento en la base de datos origen debido a la forma en que se extrae la información de los cambios, haciendo uso de los archivos “redo logs”.

Ambiente utilizado:

Base de datos:

  • Base de datos origen:             /u01/app/oracle/product/10.2.0/db_1
                                                             (Oracle 10g – 10.2.0.5.0)

  • Base de datos temporal:      /u01/app/oracle/product/10.2.0/db_1

                                                             (Oracle 10g – 10.2.0.5.0)
 

  • Base de datos objetivo:         /u01/app/oracle/product/12.1.0/db_1

                                                            (Oracle 12c – 12.1.0.1.0)
 

Oracle Golden Gate:

  • Versión en el servidor origen:         11.1.1.1.0 for Oracle 10g

                                                                        /u01/app/ogg/10g
 

  • Versión en el servidor objetivo:       12.1.0.0 for Oracle 12c

                                                                        /u01/app/ogg/12c

Migración con Oracle Golden Gate

Resumen:

  • Realizar un respaldo completo de la base de datos origen  e iniciar la extracción de los cambios en la misma usando “Oracle Golden Gate”.
  • Aplicar el respaldo extraído desde la base de datos origen en la base de datos objetivo como una carga inicial y luego migrar la base de datos.
  • Aplicar los cambios de datos extraídos desde la base de datos origen en la base de datos objetivo (Oracle Database 12c).
  • Verificar el proceso de sincronización de los datos en la base de datos objetivo  (Oracle Database 12c).

 Iniciar la base de datos origen:

Ejecutar el script “utlrp.sql” en la base de datos origen:

Este paso solo es necesario si se encontraron objetos inválidos. Se realiza con el objetivo de dar a conocer el procedimiento completo.
