i've installed RHEL 5.1 (x86_64)
installed oracle 18.104.22.168(x86_64) by oracle user, then patched oracle 22.214.171.124 patch(x86_64).
created db and all(dbstart and dbshut, lsnrctl) is ok when use oracle user.
also i have another os user who is member of dba.
but sqlplus gives ORA-12547: TNS:lost contact.

Enter user-name: sys as sysdba
ORA-12547: TNS:lost contact
but there is no error when using sqlplus by oracle user.
i suspect there is something like file permission.
oracle user is
uid=501(oracle) gid=501(dba) groups=501(dba)
another os user is
uid=500(dbop) gid=500(dbop) groups=500(dbop),501(dba)
oracle folder is owned by orace:dba and has 775 permission.
