Oracle Database Migration Architect

Oracle Migration Exp is required skills (candidate should be very strong in it), and VMware experience. Some exposure to VCF is fine enough for this role

Responsibilities:

Oracle Database Migration

• Plan, test, and execute migrations of Oracle Database instances into VMware virtual machines within the existing VCF 9.1 environment
• Perform Oracle workload migrations between virtual machines and across environments with minimal disruption to production services
• Validate data integrity, connectivity, and application compatibility before and after each migration
• Right-size virtual machine configurations (vCPU, memory, storage I/O) based on Oracle Database workload requirements and VMware best practices
• Document migration plans, runbooks, and post-migration validation reports

Oracle Database Configuration & Best Practices on VMware

• Configure Oracle Database instances and schemas in accordance with VMware and Oracle best practices for virtualized database workloads
• Deploy and manage Oracle Data Guard and Real Application Clusters (RAC) within the VMware virtual environment, including listener configuration, standby management, and failover testing
• Apply VMware-specific Oracle tuning recommendations including NUMA alignment, large memory pages, storage latency settings, and vCPU scheduling
• Assist with Oracle Database performance troubleshooting in the VMware context, working with the platform team where infrastructure-level investigation is required

Day-to-Day VMware Operations

• Operate confidently within a vSphere 6.7 environment — provisioning, cloning, snapshotting, and reconfiguring virtual machines as needed
• Navigate and work within a VCF 9.1 environment, utilizing existing workload domains and pre-configured resources for Oracle VM deployments
• Consume NSX-T virtual network segments and gateways already in place — connecting VMs to the correct segments and troubleshooting basic VM-level connectivity issues
• Work with the storage team to present and configure datastores and VMDKs appropriately for Oracle Database performance requirements

Collaboration & Documentation

• Work closely with DBA, application, and platform teams to coordinate migration windows and post-migration validation
• Produce clear, accurate technical documentation including migration runbooks, VM build standards, and Oracle configuration baselines
• Raise and track infrastructure requests with the platform team for any VCF, NSX-T, or HCX-related changes that fall outside the scope of this role

Required Qualifications:

Experience

• 4+ years of hands-on experience working in VMware vSphere environments, including vSphere 6.7
• Working knowledge of VMware Cloud Foundation (VCF) 9.1 — sufficient to navigate the environment, understand workload domains, and deploy VMs within an existing platform
• Working knowledge of VMware NSX-T — understanding of virtual network segments and logical gateway topology; ability to connect VMs to existing segments and diagnose basic connectivity issues (no design or implementation responsibility)
• Proven experience migrating Oracle Database workloads into and within VMware virtual environments
• Hands-on experience with Oracle Data Guard and/or Oracle RAC in a virtualized context
• Solid understanding of Oracle Database configuration best practices on VMware (NUMA, vCPU, memory, storage I/O)

Technical Skills

• VMware vSphere 6.7 — VM provisioning, cloning, snapshots, resource configuration, and vCenter management
• VMware VCF 9.1 — workload domain awareness, VM deployment within existing domains (operational, not architectural)
• VMware NSX-T — understanding of network segments, T1 gateways, and overlay networking; connecting and troubleshooting VMs at the network edge (no NSX-T design, deployment, or management required)
• Oracle Database (19c, 21c, or 23ai) — installation, configuration, migration, Data Guard, RMAN backup/restore
• Oracle migration tooling — RMAN, Data Pump (expdp/impdp), GoldenGate, or Transportable Tablespaces
• PowerShell, PowerCLI, and/or shell scripting for routine VMware and Oracle operational tasks
