BaryTech Solution
We executed a robust IT solution, featuring state-of-the-art server hardware with RAID 10 for data integrity, Microsoft Hyper-V virtualization for efficient resource allocation, and a seamless migration of Oracle databases to RHEL VMs, ensuring optimal performance and reliability for XYZ Corporation’s applications.
Server Hardware and RAID Configuration
We began by recommending and procuring state-of-the-art server hardware, which included redundancy for enhanced reliability. RAID 10 was configured to ensure data integrity and fastread/write operations. The hardware was designed to accommodate future expansion.
Microsoft Hyper-V Virtualization
Microsoft Hyper-V was selected as the virtualization platform. We set up Hyper-V on the new servers and configured them for optimal performance, making sure that resources were efficiently allocated to the virtual machines (VMs).
Linux (RHEL) VMs for Databases
We created multiple RHEL-based virtual machines to host Oracle databases. These VMs were optimized for database performance, with separate disks for data, log files, and backups.
Oracle Database 19c Installation and Preparation
Oracle Database 19c was installed on the RHEL VMs, and we conducted necessary pre-installation tasks, including setting up Oracle user accounts, directories, and networking configurations.
Cross-Platform Oracle Database Migration
We carefully planned and executed the migration of Oracle databases from Windows Server to RHEL. This involved data export, transformation, and import to ensure a smooth transition. We also conducted extensive testing to guarantee data integrity.
Application Configuration and Testing
The client’s applications were configured to connect to the newly migrated Oracle databases. Rigorous testing was performed to validate the connectivity, data consistency, and overall system performance.
