How to enable ptrace?

Dear community

Have you ever enabled ptrace in oracle linux?

server:

Red Hat Enterprise Linux Server release 7.9

oracle kernel 3.10.0-1160.95.1.el7.x86_64

Issue:

sysctl kernel.yama.ptrace_scope

must return 0 or 1 to be enabled, i've got 3

Everywhere I try to edit / change it to 0 is unsuccessful.

here

[root@<REMOVED> boot]# less config-3.10.0-1160.95.1.el7.x86_64 | grep -i yama

CONFIG_SECURITY_YAMA=y

CONFIG_SECURITY_YAMA_STACKED=y

or even here

[root@<REMOVED> sysctl.d]# grep -i yama *

10-kernel-hardening.conf:kernel.yama.ptrace_scope = 0

10-network-security.conf.9533.2023-02-08@09:59:45~:kernel.yama.ptrace_scope = 0

[root@<REMOVED> sysctl.d]# pwd

/etc/sysctl.d

[root@<REMOVED> sysctl.d]#
