Technical Tips

When a new release has been successfully tested on a test system, how do you migrate the new release to the production system?

Once new release testing has been completed and a decision is made to migrate the new release into production, production can be updated from the test system in a couple of different ways. However, for either of these techniques to be successful, the following conditions must be true:

• The test system must have initially been created by making a clone of your current production system (Please see the PHOENIX OS Installation Guide “Chapter 3 - Preferred Test Environment: Duplicate the Production System” or the PREFERENCE OS Installation Guide “Chapter 5 - Stage 2: Creating a Test System”).
• The appropriate reinstall procedure for upgrading your production release to the new release was used (Please see the PHOENIX OS Installation Guide Chapter 8 - Reinstalling PHOENIX” or the PREFERENCE OS Installation Guide “Chapter 5 - Stage 3: Obtaining the Reinstallation JCL”).

1. Run GSPFASBK to backup the production system
2. RENAME the following production system datasets:
   
   
   • production.LINKLIB  to  old.LINKLIB
   • production.MACLIB  to  old.MACLIB
   • production.USERFONT  to  old.USERFONT
   • production.SAMPLIB  to  old.SAMPLIB
   • production.PRG0100  to  old.PRG0100
   • production.PRG0199  to  old.PRG0199
      
3. RENAME the following test system datasets to the production DSN's:
   
   
   • test.LINKLIB  to  production.LINKLIB
   • test.MACLIB  to  production.MACLIB
   • test.USERFONT  to  production.USERFONT
   • test.SAMPLIB  to  production.SAMPLIB
   • test.PRG0100  to  production.PRG0100
   • test.PRG0199  to  production.PRG0199
      
4. The production system should now be at the new release level retaining all customization.

1. Run GSPFASBK to backup the production system
2. Run the GSPRESTR utility to copy the following test system datasets to the corresponding production system dataset:
   
   
   • test.PRG0100  to  production.PRG0100
   • test.PRG0199  to  production.PRG0199
      
3. Copy the following test system PDS datasets to the corresponding production system dataset:
   
   
   • test.LINKLIB  to  production.LINKLIB
   • test.MACLIB  to  production.MACLIB
   • test.USERFONT  to  production.USERFONT
   • test.SAMPLIB  to  production.SAMPLIB
      
4. The production system should now be at the new release level retaining all customization.
