I am trying to prepare the server running Oracle linux 8.8 for Oracle database 19c installation.
I installed oracle-database-preinstall-19c.rpm and ulimit -l value started showing unexpected to me value of ‘64’.
It's my first time configuring a server so i need some help in understanding ‘ulimit -l’ value.
I expect it to be the value set in the /etc/limits.conf for * (all) users and value from /etc/limits.d/oracle-database-preinstall-19c.conf for ‘oracle’ user but i see ‘64’ using both xrdp connection and local log in for all users.
However when i open a console and switch user using ‘su’ and run ‘ulimit -l’ i get the expected value that was set in .conf files.
/etc/security/limits.d/oracle-database-preinstall-19c.conf file contains following lines for setting memlock value:
oracle soft memlock 134217728
oracle hard memlock 134217728
/etc/security/limits.conf file contains following lines for setting memlock value:
* soft memlock 134217728
* hard memlock 134217728
no other /etc/security/*.conf files set ‘memlock’ value. The server has 96GB of memory and x86_86 architecture.
sudo grep pam_limits /etc/pam.d/* shows:
/etc/pam.d/fingerprint-auth: session required pam_limits.so
/etc/pam.d/password-auth: session required pam_limits.so
/etc/pam.d/runuser: session required pam_limits.so
/etc/pam.d/system-auth: session required pam_limits.so
grep Huge /proc/meminfo shows:
AnonHugePages: 0 kB
ShmemHugePages: 0kB
FileHugePages: 0kB
HugePages_Total: 0
HugePages_Free: 0
HugePages_Rsvd: 0
HugePages_Surp: 0
Hugeagesize: 2048 kB
Hugetlb: 0 kB
Transparent hugepages are set to ‘never’.
I haven't found any ‘memock’ values in systectl show user-$(id -u oracle).slice
I also have set vm.hugetlb_shm_group value in /etc/sysctl.d/99-hugetlb-shm-group.conf in case that matters.
I haven't installed Oracle database yet.
So can anyone help me?
Why is ‘ulimit -l’ value set to 64?
Is it okay?
I can provide more environment settings and values if needed.
