IMS DBA Consulting
What is an IMS Database?
IMS is a mainframe database management system which is composed of separate and distinct database datasets. Each database is organized into a hierarchical structure with a root segment and multiple child segments under each root. Large IMS databases can be separated into dataset groups or partitioned by key into individual partitions.
IMS Fast Path databases are optimized for extremely high performance of simple update transactions and partitioned into Fast Path Areas. IMS full function databases provide capabilities to sequentially or randomly retrieve each segment. They can also provide for logical relationships between segments. IMS HAL databases provide high availability and partitioning for large database structures.
Why Tune IMS?
IMS Databases provide access to data without manual intervention. Database reorganizations can be regularly executed without performing database tuning analysis. The growth in size of the database structures and changes in data content can cause databases to be inefficiently allocated. This inefficiency would cause excess use of CPU and I/O subsystems.
