I was born in Spain and then travel to Paris where I start studying databases.
Then I go back to Spain and since 2005 I work exclusivly as Oracle dba. During several years I work in diferents environments and I touch a lot of Oracle technology. Here is part of this knowledge. Most recently, I work with Oracle 12c grid version, Oracle dataguard 11g and some other technologies as Rman o Oracle FlashBack.
Citare aqui unas de las operaciones que realize con exito:
- Mantenimiento de las instancias de Oracle
- Migración Grid control de 10G a 11G
- Migración de datos de un diskgroup a otro. (Cambiar discos de cabina)
- Copia de seguridad diseño de las políticas de recuperación de las bases de datos
- Instalación diseño e instalación de nuevo RAC entornos ASM ersión 11gR2
- Seguimiento con las herramientas de monitoring de OVO, Grid Control y Ganglia
- Creación de nuevas alarmas para OVO
- Restoración de bases de datos con RMAN duplicate
- Formación de un equipo de desarolladores con Oracle FlashBack. Simulamos perdidas de datos tras una release y recuperamos los datos perdidos gracias a FB
