SCC/DLimit (DLIMIT)  
 

Overview
SCC/DLIMIT provides storage administrators and users with an up-to-the-minute view of the storage space used by the data belonging to an application.

Tracking and monitoring space use and preventing unlimited growth in application space is particularly important in a system-managed environment, where DASD volume boundaries are eliminated.

DLIMIT allows installations to interactively set, change, and view accounts and quotas for disk space use at the application level, eliminating the need for tedious analysis of out-of-date DASD reports.

 
     
 

Space accounts for each application.
DLIMIT uses the same flexible rules language as the other members of the Storage Control Center to assign datasets to accounts based on name, SMS class, or other criteria.

Datasets may be assigned to multiple accounts, allowing usage to be tracked at the user, application, or departmental level.

High Water marks and space statistics.
DLIMIT keeps track of the current space used within an account, the highest amount used, the maximum allowable amount, and other important information in real time.

The SCC rules language allows warnings to be issued for accounts which exceed their limit, or if desired, new allocations for over-budget accounts can be prevented.

ISPF Interface.
An easy-to-use ISPF interface allows users to view their account status interactively, and allows storage administrators to easily set or change account criteria.
