A high-performance hierarchical database and transaction manager for z/OS that secures, scales, and modernizes critical business applications
Power your enterprise with IMS
IBM Information Management System (IMS™) is a secure, high-throughput database and scalable transaction manager on z/OS®. Designed for growth, IMS enables fast, reliable data and online transaction processing and seamless integration with modern cloud-native tools. IMS contains two major components that can be used together or separately: IMS Transaction Manager (TM) and IMS Database Manager (DB).
Process billions of transactions daily with trusted data integrity and built-in recovery capabilities.
Protect sensitive data with IBM Z® pervasive encryption and access controls with no code changes required.
Connect IMS to cloud applications using Java™, APIs, and IBM z/OS Connect for easier modernization.
Automate IMS operations with Ansible and streamline deployments for faster delivery.
Features
Modernize IMS applications by leveraging Java interoperability with COBOL or PL/I. Seamlessly access data across distributed systems via the IMS TM resource adapter and RESTful APIs, empowering digital transformation initiatives.
Speed up deployment cycles with certified Ansible collections for IMS. Enable continuous integration and delivery pipelines by automating repetitive tasks and enhancing collaboration across teams.
Enable z/OS data set encryption and IBM Z pervasive encryption with no application changes. IMS delivers strong protection and compliance for sensitive data in regulated environments.
Access IMS data from cloud-native applications via SQL or API. With universal drivers and IMS integration into IBM z/OS Connect, developers can use standard interfaces to extend legacy systems to modern platforms.

Frequently asked questions
Monthly license charges (MLC) apply to many IBM Z software products, including IMS. Pricing and terms and conditions for MLC products are based on the pricing metric you select. MLC pricing metrics can roughly be grouped into two categories: full capacity based pricing metrics and sub-capacity capable pricing metrics.
No. Both components of IMS must use the same pricing metric. They can either both be MLC or both be OTC.
For example: if you use both IMS Database Manager and IMS Transaction Manager, you cannot use the one-time charge (OTC) pricing metric for one and the monthly license charge (MLC) pricing metric for the other.
