Q. Are there Disaster Recovery procedures for RPG Toolbox?
A. You can install it from scratch, but then you would lose any custom settings you have applied to the Toolbox.
It would be best if you save the licensed program 4RPGBOX using the SAVLICPGM command as part of your backups and restore it to the DR system. That would save the RPGTOOLBOX library and any settings you have applied.
