nohup command failure on HP-UX 11.00

Ing. Marco Tricase — Thu, 18 Jan 2001 14:21:57 GMT

using the following line command:
nohup /opt/tivoli/tsm/client/ba/bin/dsmc sched > /dev/null 2>&1 &
directly, the command nohup runs good, but inserting the same line inside a script, the process dsmc die at the end of the script.
TIA.

Have you tried redirecting to a real file and check it's contents after the demise of the program invoked?

Hmm. very interesting. Certainly this should not happen normally. Ive just tested it with scripts and it works fine.

Either your dsmc program is detecting that the parent process had died (existed) and thus its parent pid process has now changed from whatever to PID 1, or it is trapping a signal that is sent to the child informing it of the death of the parent. The problem seems to lie with your dsmc program.

Instead in your script you could add in on the last line of it the command wait() which means it will not exit itself until the backgrounded process also finishes.

Hi everybody,
fortunately we have solved the problem:
the process launched by nohup doesn't run correctly because nohup doesn't read the environment variables of the root .profile.
The solution used is to create a new command file with the environment variables set and to launch it with the nohup command.
Regards.
