Buen día, Entiendo que necesita soporte directo para una migración ETL con Informatica PowerCenter, garantizando un proceso limpio, controlado y totalmente auditable desde Oracle/SQL al nuevo esquema. Tengo experiencia en el diseño de mapeos, sesiones y flujos de trabajo robustos, incorporando validaciones de calidad, gestión de errores y registros detallados para periodos críticos de migración nocturna. Puedo garantizar una conciliación del 100 % mediante recuentos y sumas de comprobación, además de documentar cada mapeo en el repositorio y entregar un manual claro de implementación y reversión, dejando el paquete versionado y listo para control de calidad/producción con total confianza. ¿Ya están definidos el periodo de migración nocturna y los volúmenes estimados para que podamos ajustar el diseño del flujo de trabajo desde el principio? Gracias. Nassim

Buenos días, he realizado proyectos en Powercenter creando DWH para luego extraer los KPIs y realizar cuadros de mando (Puede visitar mi perfil para ver toda mi amplia experiencia en BI y bases de datos). Estaría interesado en participar en su proyecto, por ello me gustaría abordar más en profundidad el objetivo del proyecto (si es una migración pura, es una migración con transformación de datos... etc. Entiendo que la base de datos original es SQL Server). ¿Qué tipo de colaboración propone? ¿Es una colaboración por hitos, o por cumplimiento de horario? Por favor, si lo desea contacte por el chat de la plataforma, al pertenecer a la misma zona, disponemos la ventaja adicional de compartir idioma y horario. Quedo a la espera de sus noticias, Un saludo.

Hola, Tengo experiencia desarrollando procesos ETL en Informatica PowerCenter para migraciones complejas entre Oracle y SQL Server, incluyendo mappings, sesiones y workflows con control de calidad, manejo de errores y trazabilidad completa. He trabajado en proyectos donde la prioridad es exactamente la que mencionas: migración limpia, auditable y con validaciones estrictas de conteos y checksums antes de promover a QA o Producción. Puedo apoyarte directamente en la construcción de mappings, diseño de transformaciones, configuración de sesiones y workflows, así como en el registro detallado de eventos y excepciones. También puedo documentar cada mapping en el repositorio y preparar un pequeño manual de despliegue/rollback para que el proceso quede totalmente controlado. Me adapto a ventanas nocturnas de ejecución y puedo ayudarte a garantizar que todos los procesos corran sin fallas y con coincidencia del 100 % entre origen y destino. Manejo PowerCenter, SQL, PL/SQL, Oracle, Repository Manager y Workflow Monitor, además de buenas prácticas de versionado para entregar un paquete listo para promoción. Si quieres, puedo preparar un plan de trabajo inicial para organizar los mappings prioritarios y el orden de migración.

Hi there, I see you're gearing up for a migration project involving Informatica PowerCenter and Oracle, focused on ensuring a seamless, auditable ETL process. I understand the importance of a clean and controlled migration to meet your operational needs and maintain data integrity throughout the transition. To ensure a smooth execution, I propose developing robust mappings, sessions, and workflows within PowerCenter that incorporate error handling, quality validations, and detailed logging of events. I will document each mapping thoroughly in the repository and provide a deployment/rollback manual. My experience in similar migrations ensures that I can meet the required success criteria, including flawless execution during the defined overnight window and maintaining 100% match on counts and checksums between source and destination. What specific challenges do you anticipate during the migration that we could address together? https://www.freelancer.com/u/proggon Best regards, Wahaj Barlas.

Hope you are doing well! Your requirement for a controlled, auditable Oracle data migration using Informatica PowerCenter aligns closely with projects I’ve delivered in regulated and high-volume environments. I will design modular mappings, parameterized sessions, and restartable workflows that cover extraction from SQL sources, transformation with business rules, and validated loading into the new Oracle schema. Key risks I see are data type mismatches, performance bottlenecks during the night window, and reconciliation gaps. I address these with source-to-target mapping specs, pushdown optimization where appropriate, partitioned sessions, and pre/post-SQL for staging control. I also embed row-level validation, reject handling, and audit tables capturing counts, checksums, and load timestamps for full traceability. In previous migrations (multi-TB finance and telecom datasets), I implemented reusable error frameworks, centralized logging, and automated reconciliation reports. One challenge involved checksum mismatches caused by hidden character encoding differences; I resolved it with normalization logic and binary comparison routines. You will receive repository documentation for each mapping, plus a clear deployment and rollback manual to support QA and Production promotion. This experience matched the challenges of your project and it gave me the confidence to bid. I am ready for you and waiting here. Thank you.
