Mainframe Databases - IBM Z
IBM Z Mainframe Databases deliver high-performance, secure, and scalable data management for enterprise workloads.


Mainframe databases on IBM Z

Mainframe databases are essential for providing high performance and scalability to manage large data volumes and transactions efficiently. It ensures reliability and availability for critical applications, advanced security for sensitive data, seamless data integration and robust support for large-scale transaction processing.

The two main databases deployed on IBM Z mainframes are Db2® for z/OS® and IMS. With Db2 for z/OS, you can define and manipulate your data by using Structured Query Language (SQL). IMS database software securely stores, manages and processes your most critical data with confidence.

Db2 for z/OS Products

Db2 for z/OS is an enterprise mainframe database that manages core business data and supports key business applications across an organization. It serves thousands of customers and millions of users, offering continuous availability, scalability and high security.

IBM Db2 AI for z/OS

Improve the operational performance and maintain the health of your Db2 for z/OS system by offering features like SQL optimization, system assessment (augmented by performance insights) and distributed connection control.

Db2 for z/OS Data Gate and Data Gate on Cloud

Db2 Data Gate synchronizes Db2 for z/OS data for hybrid cloud, analytics and AI initiatives with reduced cost and effort. Applications can access a transactionally consistent, synchronized copy of Db2 for z/OS data hosted on a separate system, supporting various platforms, including public cloud, on-premises and private cloud deployments.

IBM Db2 Analytics Accelerator for z/OS

A high-performance component tightly integrated with Db2 for z/OS that delivers high-speed processing of complex Db2 queries to support business-critical reporting and analytic workloads.

IBM Db2 Query Management Facility

Easily manages batch processes that must coexist and share resources with one or more CICS® online transaction systems. Create batch jobs that use control requests to release, and later reallocate, resources associated with CICS applications.

IBM Db2 DevOps Experience for z/OS

A separate data management experience can be installed and activated on top of the Unified Management Server. This browser-based graphical interface offers distinct features for managing z/OS subsystems. The role-based product modernizes Db2 for z/OS management, allowing developers to provision instances, create applications, make changes and submit them for approval.

IMS Database Software

Enhance the performance of IMS with on-demand, application-specific database and transaction management tools.

IMS Enterprise Suite

Supports open integration technologies to enable new application development and extend access to IMS transactions and data. It provides user-friendly standard interfaces, simplifies IMS metadata generation, eases application development and expands IMS access.
