Activating a Minimal Configuration

Activating a minimal configuration lets you experience managing an SMS configuration without affecting your JCL or data set allocations. During this phase, you can learn about and gain experience with the following:

ISMF applications for the storage administrator
You use ISMF applications to define and activate a minimal SMS configuration.
The new operator commands that control operation of resources controlled by SMS
New operating system commands are used to activate an SMS configuration and to display and control storage group and volume status.
How the SMS base configuration can affect allocations for non-system-managed data sets
The base configuration for your minimal SMS contains installation defaults for data sets:
- For non-system-managed data sets, you can specify default device geometry to ease the conversion from device-dependent space calculations to the device-independent method implemented by SMS.
- For system-managed data sets, you can specify a default management class to be used for data sets that are not assigned a management class by your management class ACS routine.
Using simplified JCL
With the minimal configuration active, you can use simplified JCL.
Implementing allocation standards
With the minimal configuration active, you can develop a data class ACS routine to enforce your standards.
