Products

• Dynam for VSE
• Dynam VSE Option

Issue/Introduction

   On sites where many generations (or many days) of the Power spool file are saved, a method should be available to restore (or upload) one of these generations.

 

 

Environment

Release:
Component: DYNTVS

Resolution

Example for 3 generations (3 days):
These JCL statements would be added to the standard labels after DYNAM is started:
      // TLBL OFFLA,'OFFL.CL.A,Z,DL'  -  This is the standard for output or ver=1
      // TLBL OFFLA2,'OFFL.CL.A,(-1),Z,DL'     This is for the father  
     // TLBL OFFLA3,'OFFL.CL.A,(-2),Z,DL'     This is for the grandfather

   To upload the father, this command would be entered at the console:
    POFFLOAD LOAD,LST,CAA,,X,TLBL=OFFLA2

Note: CAA is the POWER Dummy CUU.
