If oracle instance in HP-UX is set to lock sga as below:

ALTER SYSTEM SET lock_sga=TRUE SCOPE=SPFILE;

There will be error:-

SQL> ORA-27126: unable to lock shared memory segment in core

dba MLOCK RTSCHED RTPRIO

2) Run
# setprivgroup -f /etc/privgroup

3) Check that above is successful
# getprivgrp
global privileges: CHOWN
