HP Serviceguard Toolkit for Oracle Data Guard manual Root@hp46t191/home/rootkctune maxuprc=256

2.Make sure that the minimum hardware and the software prerequisites are met before the product installation is initiated. The latest installation requirements are listed on IBM web site: http://www-306.ibm.com/software/data/db2/9/sysreqs.html.

3.Use the DB2 Setup Wizard or db2install script to install the database server 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.IBM provides a utility called /opt/IBM/DB2/V9.5/bin/db2osconf in determining the minimum recommended kernel values for DB2 server. As root, run /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 the DB2 server. Login as root, modify the kernel parameters using kctune command or kcweb (graphical browser) based utility. For example, to modify the 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, see 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.

NOTE: The user names, user ID and groups shown here are for illustration purposes only.

6.Create a DB2 instance using db2icrt. The DB2 instances should be created on shared volume group.

[root@node1 /]><DB2_installation_dir>/instance/db2icrt -a client -u db2fenc1 payroll_inst

7.In case of logical multi-partitioned database installation, edit DB2 node configuration file db2nodes.cfg in the exported instance owner home directory to define the database partitions that participate in a DB2 instance.

For example:

[payroll_inst@node1 ~]> vi /home/payroll_inst/sqllib/db2nodes.cfg

0node1 0 node1

1node1 1 node1

8.In case of physical multi-partitioned database installation, edit the DB2 node configuration file db2nodes.cfg in the exported instance owner home directory to define the physical and logical database partitions that participate in a DB2 instance.

For example:

[payroll_inst@node1 ~]> vi /home/payroll_inst/sqllib/db2nodes.cfg

0node1 0 node1

1node1 1 node1
