Hello all,
I have set a bshell command in order to track some fishy query:
-- -dbgres -keeplog -logfile resource.txt

the first line of the resource.txt is

Can´t change process group

My question is:
What is the "process group"? and Where I allow the user to change that Process group?

This is the only difference between users that runs a particular session "normal" and a user that runs the same session and hangs.

Any clue?
Thank you in advance.

it's a system call that internal to the bshell.

you can't change it. Later porting sets surpress that error.

Dave

Thanks Dave,
Actually, I have done a search of that message that appears me. And I realized that the message is related with the SO. Follow this, I verify the set up user at operating system level and, in the parameter "USER SHELL" I have put the ksh as shell.

Suspecting that this is the problem I switched to sh, and the message not appear any more.

I check with the user and, my suprice was that the session is running normal!

Changing this parameter was the solution? Honestly I don´t know, but it works for me.

I want to thank everyone who help me on track this problem, and I want to share this "solution" to all who have a similar trouble. Maybe they will find this helpful.

Thank you again Dave.
