Asynchronous DB2 Image Copies

MasterCopySet® for DB2 on z/OS

Together with MasterReorg and MasterCopy, MasterCopySet is part of the MASTER-UTIL line, an automated software suite ensuring reorganizations, restores and backups.

The Problem

  • In case of a software or hardware problem, the data downtime must be limited to a minimum
  • It is becoming increasingly difficult to create consistent backups ready to be reloaded in case of a problem, because of the number and volume of the objects concerned
  • It is equally difficult to create consistent backups ready to be transferred to other application systems
  • These essential administrative processes run in a smaller and smaller utility batch window

The MasterCopySet solution

MasterCopySet is a unique solution that:

  • Asynchronously creates share level reference Full Image Copies (FIC)
  • Synchronizes the object copies to a specific point for the application

MasterCopySet recreates a FIC for the QUIESCE simply from:

  • The last available FIC
  • Any IICs (Incremental Image Copies)
  • Log data
  • The data remains available for all the applications during execution of MasterCopySet

The advantages of MasterCopySet

  • It generates Full Image Copies asynchronously without interfering with DB2 operation
  • It decreases recovery time by limiting the number of images copies to be taken into account
  • It decreases recovery time by limiting the quantity of log files to be taken into account
  • It generates share level REFERENCE Full Image copies registered to DB2
  • It automatically manages the number of tape drives required for execution
  • It processes several objects simultaneously
  • It is downwardly compatible with standard DB2 utilities

We are prepared to demonstrate to you the excellent return on investment you will achieve with MasterCopySet.
