If you plan to use an IBM DB2 database when you install vCenter Server, you must configure the database user and group.

You can configure a DB2 database for vCenter Server either locally on the same Microsoft Windows machine as vCenter Server or remotely on a network-connected Linux, UNIX, or Windows host.

Before you configure your DB2 user and group, do the following tasks:

Review the software requirements for vCenter Server with DB2.

Make sure that a DB2 instance is created and configured for incoming TCP connections. For more information, see the DB2 documentation Web site.


Create an initial user on the operating system.

You must create a user on the operating system. By default, DB2 uses the operating system authentication for all its database users. This procedure assumes that you have created a user called vcx.


If the database is hosted on a Microsoft Windows machine, add the user vcx as a member of the group DB2USERS.

Ignore this step if you are running the database on a remote UNIX or Linux system.


Create a user group called DBSYSMON and add the user vcx as a member.


Open a DB2 command window or Command Line Processor (CLP) as the DB2 instance owner.

On Microsoft Windows, select Start > IBM DB2 > DB2Copy1 > Command Line Tools > Command Window.

On Linux or UNIX, open a terminal and switch your user to the DB2 instance owner.


In the DB2 command window, run the following command to add the group DBSYSMON to the group of users capable of database system monitoring:

db2 update dbm cfg using sysmon_group dbsysmon

This command affects all databases in this instance.

You now have a DB2 database user that you can reference in the vCenter Server installer.

Add the database instance registry variables.
