Overview

Optimize IMS Database Performance

IMS™ Sequential Randomizer Generator for z/OS® generates a randomizing module that provides access to Hierarchical Direct Access Method (HDAM), Data Entry Database (DEDB) or Partitioned HDAM (PHDAM) segments directly or sequentially. Sequential database processing offers simplicity in data storage and speed and efficiency when handling large volumes of data.

Features

Faster access and smarter data control

Access HDAM and DEDB databases in logical key sequence while preserving their efficient direct access capabilities. Retrieve data in the required order without sacrificing the performance advantages that support fast and reliable database operations.
