Dear Team,
I was able to fix all persistent issues with Batch Script on my server and was able to launch my job using COZLAUNCH.
For an email server problem, i had to restart my Windows 2012 server machine and now I get the following error when i invoke a job from Z/Os
CoZLauncher.E.: userxàmachine1 target command '<default shell>' ended with RC=66
Let me know if this error has been encountered before.
