Issue/Introduction

This document illustrates how to reduce the amount of space used by a View database.

Environment

• View®
• OM View for z
• Output Management View® for z/OS

Resolution

In the event that a View database has been over-allocated, or if the requirements of the database has changed such that the amount of disk space needs to be reduced, here are procedures that can be used to alter the amount of space used by the database, depending on the availability of DASD space:

• All tasks against the database must be brought down. These tasks would include:
  
  
  • SARSTC - the View started task
  • SARFSS - any ACIF/Xerox/Text report collector tasks
  • SARXMS - online tasks using cross-memory services
  • RMOSTC - any CA Deliver tasks which write directly to the database
    (RMOPARM: ARCHn=DIRECT[/...]
    
    
• If there is NOT sufficient DASD space available to allocate the new database, follow these steps:
  
  
  
  • SARDBASE UNLOAD:
