Using the DB2 database Toolkit in a Serviceguard Cluster in HP-UX Release README: B.06.00

deferring the instance creation. The destination directory for DB2
server
must be the same on all cluster nodes. DB2 installation must be
done by a
root user.
4. Modify the Kernel parameters if required. IBM
provides
/opt/IBM/DB2/V9.5/bin/db2osconf utility to aid
administrators in
determining the minimum recommended kernel values for DB2 server.
As root,
/opt/IBM/DB2/V9.5/bin/db2osconf or /opt/IBM/DB2/V9.7/bin/db2osconf
utility to aid administrators in determining the minimum recommended
kernel values for DB2 server. Login as root
modify the kernel parameters using 'kctune' command or kcweb
(graphical
browser) based utility. For example, to modify value of maxuprc
execute as
root the following:
root@hp46t191:/home/root>kctune maxuprc=256
For more information regarding the recommended kernel values
for DB2
server, visit IBM DB2 Information center,

5. Create required users and groups on all cluster members
To create required groups using command line utilities, execute
as root:
[root@node1/]> groupadd -g 400 db2iadm1
[root@node1/]> groupadd -g 500 db2fadm1
[root@node1/]> groupadd -g 600 dasadm1
To create required users using command line utilities, execute as
root:
[root@node1/]> useradd -u 400 -g db2iadm1 -m -d
/home/payroll_inst payrollinst
[root@node1/]> useradd -u 500 -g db2fadm1 -m -d /home/db2fenc1
db2fenc1
[root@node1/]> useradd -u 600 -g dasadm1 -m -d /home/dasusr1
dasusr1
See useradd (1M) and groupadd (1M) man pages for additional
details. Please
note that user names, user id.s and groups shown here are for
illustration
purposes only.
6. create a DB2 instance using db2icrt.
[root@node1 /]> <DB2_installation_dir>/instance/db2icrt -a client
-u db2fenc1 payroll_inst
