Extending the directory schema Windows

account is defined, adding a domain user to the local Administrators group on the server does not grant the domain user SYSADM authority to this group.

To avoid adding a domain user to the Administrators group at the domain controller, create a global group and add the domain users to which you want to grant SYSADM authority to it. Then update the DB2 configuration parameter SYSADM_GROUP with the name of the global group.

To update the DB2 configuration parameter, enter the following commands:

db2 update dbm cfg using sysadm_group global_group db2stop

db2start

Extending the directory schema (Windows)

If you plan to use the Lightweight Directory Access Protocol (LDAP) directory server feature with Windows 2000 or Windows Server 2003, you should extend the Active Directory schema to contain DB2 object classes and attribute definitions. You should perform this task before you install any DB2 products.

Extending the directory schema ensures that:

vThe default DB2 instance, created during the installation, is cataloged as a DB2 node in Active Directory provided the installation user ID had sufficient privileges to write to Active Directory.

vAny databases that the user creates after installation will automatically be cataloged into Active Directory.

If you decide to install your DB2 product and create databases before you extend the directory schema, you will have to manually register the node and catalog the databases.

Prerequisites:

Your Windows user account must have Schema Administration authority.

Procedure:

To extend the directory schema:

1.Log onto the domain controller.

2.Run the db2schex.exe program from the installation CD with a user account that has Schema Administration authority. You can run this program without logging off and logging on again, as follows:

runas /user:MyDomain\Administrator x:\db2\Windows\utilities\db2schex.exe where x: represents the CD drive letter.
