For years I have spawned shell scripts with nohup and ampersand and they run whether or not I stay logged in. Recently a client told us that we had to set a keep alive timeout on all of our Redhat 7.6 Linux servers. Our sysadmin set the following parameters in the sshd_config file on all of our Redhat 7.6 servers:
Now when I try to nohup an Oracle database clone script or some other type of Oracle database shell script, the script tends to die within 15 minutes. If I run the script through crontab it works fine. I have tried running tests where I use disown after spawning a script with nohup and ampersand, but that doesn't seem to help. Since the scripts are using sqlplus, and that is spawning its own process, my assumption is that the parent process is idle, even though the child process is not idle. Hence, the script dies.
I would use crontab, but then I need to remember to take the job out of crontab, otherwise it will continue to run on the schedule that I used. Does anyone have any suggestions on how to run scripts without them being killed by the OS?

uudemon.cleanu
uudemon(4) Kernel Interfaces Manual uudemon(4)NAME
uudemon.admin, uudemon.cleanu, uudemon.hour, uudemon.poll - Administrative shell scripts for polling remote systems, cleaning up spool
directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons
SYNOPSIS
These shell scripts reside in the following directory:
/usr/lib/uucp
DESCRIPTION
All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the scripts, remove
the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file.
This script reports status to the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the
results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID (uucpa) or
root. This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com-
mand is run with the following parameters: -C7, -D7, X2, -o2, -W1. This script runs the uusched and uuxqt daemons in the background. This
script polls the systems listed in the /usr/lib/uucp/Poll file. The uudemon.poll script should be scheduled before the uudemon.hour
script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script.
FILES
Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files. Contains the uucp file.
