Try it at no cost Browse IMS events

IBM Information Management System (IMS™) is a hierarchical database and transaction management system available on z/OS®. 

IMS serves as an application platform, comprising a secure database management system and a scalable transaction manager built for high-performance online transaction and data processing.

By leveraging APIs and distributed connectivity, IMS can integrate with modern tools and emerging technologies, enabling it to host and extend the functions of your business-critical applications.

IMS contains two major components that can be used together or separately:

  • IMS Transaction Manager (TM): Host mission-critical applications to support billions of transactions per day1.
  • IMS Database Manager (DB): Securely store, manage and process critical data with confidence.

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.
