Greetings and Happy New Year!
You can't judge like that what is good/bad...
Oracle is no ordinary user: many users access to files using oracle UID the same for processes etc
So it will depend on the size of your RDBMS or how many instances you have running on a server, how many processes are "oracle" etc the same for files and file size: no ordinary user would produce a file on a system the size of a full export (oracle)...
Why unlimited as value is not a good idea unless you know what you are doing AND what the others do:
Just an example: if a coder badly checked his new code that went in production ( or just a bug...) fall on a case you case have files opening but not closed correctly, worse though quite funny when it occurs: executing an infinite loop opening new processes...
You end with a freeze of the system where if lucky and an admin can connect will shutdown gracefully the box, more severe no one can connect and you have no other choice but to power off...
AIX at least lets you define on a specific user basis, may not be the case of all Unixes you see
Addendum:
Q: Do you have any issues? Giving a lot of resources will give you peace ( no errors or warning of running out of resources...) only that waste of resource will affect performance, if that is OK with you and production are happy, well why worry except for the case you do have an issue, it will be in proportion with what you gave

reboot(8) System Manager's Manual reboot(8)
NAME
reboot - Restarts the machine
SYNOPSIS
/usr/sbin/reboot [-dlnq]
DESCRIPTION
When the system is running and multiple users are logged in, use the shutdown -r command to perform a reboot operation. If no users are
logged in, use the reboot command.
The reboot command normally stops all running processes, syncs the disks, logs the reboot, and writes a shutdown entry in the login
accounting file, /var/adm/wtmp.
The reboot command uses the sync call to synchronize the disks, and to perform other shutdown activities such as resynchronizing the hard-
ware time-of-day clock. After these activities, the system reboots. By default, the system starts and the file systems are automatically
checked. If the start-up activities are successful, the system comes up in the default run-level.
You must have root privileges to use this command. Using the -n flag can result in file system damage.
FLAGS
Generates a crash dump of the system before halting it. Can be used with any of the other flags. Does not log the reboot using syslog
Does not sync the disks or log the reboot using syslog Performs a quick reboot without first shutting down running processes; does not log
the reboot using syslog
EXAMPLES
To enable the default reboot action, enter: reboot This command causes the system to stop all running processes, sync the disks, log the
shutdown, and perform other routine shutdown and reboot activities. To shut down the system without logging the reboot, enter: reboot -l
This command shuts down the system and performs all shutdown and reboot activities, except logging the shutdown. To reboot the system
abruptly, enter: reboot -q This command reboots the system abruptly without shutting down running processes.
FILES
Specifies the command path Specifies the login accounting file Specifies the path of the syslog daemon
