日本 Oracle 公司（總部：東京都港區，社長：三澤 智光）今日宣布，大東建託株式會社（總部：東京都港區，代表取締役社長執行役員 CEO：竹内 啓）已開始將支援會計、銷售支援、內部入口網站等超過 60 個核心業務系統的約 40 個資料庫基礎設施，遷移至 Oracle Exadata Cloud@Customer 上的 Oracle Exadata Database Service。此專案預計與傳統的本地端升級相比，建置成本可節省約 25%，營運成本可節省約 32%，同時還能提高基礎設施的可用性並大幅加速各種處理任務。
大東建託株式會社主要從事以租賃住宅的建設、管理和仲介為中心的房地產相關業務，其管理的租賃住宅戶數約有 130 萬戶，位居業界首位*。該公司過去在資料中心營運著分散在多台伺服器上的 Oracle AI Database，並將其作為支援約 18,000 名集團員工使用的核心業務（包括會計系統、銷售支援和內部入口網站）的資料庫基礎設施。然而，硬體老化、個別維護和營運多個資料庫的負擔日益增加，以及授權成本的優化已成為重要的挑戰。此外，隨著業務成長導致資料量增加和處理負載波動，公司需要一個能夠彈性且快速擴展資源的基礎設施進行更新。

為了解決這些挑戰，大東建託已開始建置新的資料庫基礎設施。該公司正在導入 Oracle Real Application Clusters (RAC) 和 Oracle Exadata Database Service on Oracle Exadata Cloud@Customer，將其約 40 個資料庫基礎設施整合為一個高可用性、高效能的平台。此整合預計將簡化營運、降低成本並增強系統穩定性。
