Oracle Tips by Burleson Consulting

RAM memory fencing in HP/UX

In HP/UX, the LOCK_SGA=true init.ora parameter is used. In addition, the following steps must be completed as root:

Do the following:

1) Login as root:
%su root

2) Create the file "/etc/privgroup":
$vi /etc/privgroup

3) Add line "dba MLOCK" to file.
Note: The group dba is assuming the oracle owner's ID is part of
the dba group.

4) As root, run the command "/etc/setprivgrp -f /etc/privgroup":
$/etc/setprivgrp -f /etc/privgroup

The above is an excerpt from the "Oracle UNIX Administration Handbook" by Oracle press, authored by Donald K. Burleson.
