IMS and modern storage subsystems: How to improve performance
Available in replay for your convenience, register now.
Developed for: Database administrators and systems programmers
Technical level: Basic – intermediate
As IMS databases and system datasets grow in size and activity, they present performance and availability challenges to users. Modern storage subsystems offer many performance enhancements, but users must understand how these functions may be used with IMS™.
Modern storage subsystems are nothing like the old physical cylinder, track and record devices for which IMS was originally designed. Join us for this complimentary teleconference for an overview of these storage subsystems as they relate to IMS. Topics to be covered include caching, virtualization, Parallel Access Volumes (PAV), Multiple Allegiance, Extended Address Volumes (EAV), mirroring, flash copy and other storage functions from an IMS point of view. Special attention will be given to IMS support for EAV with z/OS® 1.10 which has been recently added to IMS and IMS Tools. You’ll come away from this teleconference with a good understanding of how to use these functions to improve IMS availability and performance in your shop.
You’ll learn how you can improve IMS performance by:
- Enabling multiple systems to concurrently access and update the same logical volume on the DS/8000
- Using parallel access volumes to enable z/OS systems to make multiple concurrent accesses to a single volume from a single host
- Managing few large volumes instead of many small volumes using EAV, thereby removing some layers of complexity
Speakers: Rich Lewis, IMS Advanced Technical Support Specialist; Frank Ricchio, IMS Database Developer; Bob Magid, IMS Tools Architect.
This teleconference will also be available for replay after the event.
