Ok,
at his time no answer received from user-list. Now i want ask questing

Any pythen experts are there wich can help me to get this script working?
Thanks for help.

Hello All,
I m looking for examples about phyton startup scripts... My issue is,
that i will change the priority of jobs to the starting time.
the script should look for an fullbackup-job and if this job exists
and run... all other jobs should get an higher priority. If this job
not running, configured priority should not changed.
Any one have an idea or implemented similar solution?
Thanks for help and
Best Regards
JHN
