Manual says: “Running under a hipervisor, such as VMware or Xen or KVM,
is not supported at this time. …. We do not provide specific instructions for
virtual environments and you must determine how to configure a USB port
(for the token) and Ethernet ports for their particular virtual hipervisor.”
And the customer wanted Linux on VMware …

• Tested VMware setup on our environment
• Advised the customer on preferred configuration for performance
• Initially, license USB token did not work
– Configured Linux Image to use hardware port
• Provided instructions for VMWARE departure from documentations.

• Customer specific
• Best route we provided is total refresh
• Baseline can be maintained either on mainframe or RD&T depending
on needs
• DFDSS dump/restore with replace can be used.

• RD&T system is unit Development & Test
• RD&T Data is ‘Baseline’.
• Refresh mainframe ‘production’ copy with project releases
• Use DFDSS dump/restore with Filtering

1. RD&T is Unit Test only
• Mainframe data is ’Baseline’
• Refresh RD&T data using DFDSS dump/restore
2. Customer DASD Volumes are application specific (or can
make them)
• Use Volume dumps. Volume to include user catalogs.
• Use IDCAMS import connect
