Hi all,
Greetings of the day !
Even I had faced a similar kind of issue.In my case,while launching the mainframe,I used to specify the file path and the session identifier i.e. A,B,C,....
So when I used the kill process activity,the process gets successfully killed but doesn't launch the next time.
After thorough investigation we found out that the session was not getting launched because the session identifier got changed from A to B,but we were still trying to launch by passsing the session identifier as A itself.
So the proper solutions are:
1.Avoid using Kill process utility and instead follow the step vise procedure to logout from the session and close the session.
2.And for more safety you can implement a recover resume stage and pass different session identifiers like A,B,C,....
3.If this doesn't work,then before starting the process each time,kindly end all the mainframe process from task manger.
Hope this is useful.
