Restore the BlackBerry MDS Connection

Service configuration files

You can use the BlackBerry MDS Connection Service configuration files, MdsLogin.conf and krb5.conf, to configure how

the

BlackBerry MDS Connection Service authenticates BlackBerry devices with content servers that use NTLM or

Kerberos. The BlackBerry MDS Connection Service configuration files are located in <drive>:\Program Files\Research In

Motion\BlackBerry Enterprise Server\MDS\Servers\Instance\config

When you upgrade a BlackBerry Enterprise Server, the setup application creates new MdsLogin.conf or krb5.conf files and

creates backup versions of the old

BlackBerry MDS Connection Service configuration files in the same location. If you

changed the MdsLogin.conf or krb5.conf files before you perform the upgrade, you should restore the backup versions of

the files so that the BlackBerry MDS Connection Service can authenticate BlackBerry devices with the content servers that

use NTLM or Kerberos.

Upgrade the BlackBerry database

notification system

The BlackBerry database notification system is a publish/subscribe system that is designed to reduce the number of

database queries that a BlackBerry Enterprise Server makes to the BlackBerry Configuration Database.

If you upgrade the BlackBerry Configuration Database on the computer that hosts the BlackBerry Enterprise Server, the

BlackBerry database notification system upgrades automatically.

If you upgrade the BlackBerry Configuration Database on a database server that you installed on a computer that is not the

computer that hosts the BlackBerry Enterprise Server, you can upgrade the BlackBerry database notification system

manually after you complete the BlackBerry Enterprise Server installation process.

Before you begin:

You must have the system administrator permission for the database.

1. On the database server, open the BlackBerry Enterprise Server installation files.

2. Perform one of the following actions:

• If a 32-bit Microsoft SQL Server 2005 is running in your organization's environment, in the Tools\DBNS\x86

folder, copy the RimEsp.dll file to C:\Program Files\Microsoft SQL Server\MSSQL\Binn.

• If a 64-bit Microsoft SQL Server 2005 is running in your organization's environment, in the Tools\DBNS\x64

folder, copy the RimEsp.dll file to C:\Program Files\Microsoft SQL Server\MSSQL\Binn.
