Issue/Introduction

Is there a recommended calculation for the maximum number of concurrent View users per DRAS server?

Environment

Release: 12.1.
Component: Deliver-Output Management-Interface for Native TSO

Resolution

Yes. There are formulas for calculating the maximum number of concurrent View users per DRAS server.

Calculation for the number of concurrent View users for releases 11.7 and above.

   Databases = number of View databases
   Data sets = number of data files data sets (extents) for ALL View databases)
                             + (number of data file data sets (extents) for ALL Deliver databases)
   maxusers = (maximum available below-the-line storage - (databases * 1616) - (data sets * 528)) / 2424) and drop the remainder

Example: 12MB memory => 328 users per DRAS server
