This is, however, not possible when I have sqlplus instead of cmd1. Am I right? If yes, then my problem is still unsolved.
You have said that in your case,
cmd1 is an interactive
sqlplus script that you control. You can make that
sqlplus script recognize that something in its environment has changed and use recognition of that change to do whatever it is that you want to do. If, on the other hand, your
cmd1 is not an interactive
sqlplus script or if you can't make that script recognize that something has changed in the outside world and make adjustments based on that change, then you can't do what you say you want to do and there is nothing we can do to help you make that happen (other than things we have already suggested that you have said you don't want to use).
