11. Click Save all.
12. Repeat steps 2 to 11 for each BlackBerry Enterprise Server instance that you want to use a BlackBerry Attachment
Service pool.
The BlackBerry Administration Service writes the data about the BlackBerry Attachment Service pool to the BlackBerry
Configuration Database. The BlackBerry Messaging Agent caches the pool data and uses the data to determine which
BlackBerry Attachment Service instance can process a request.
You cannot determine the BlackBerry AttachmentConnector that the BlackBerry Enterprise Server or theBlackBerry MDS Connection Service uses
If you install a BlackBerry Enterprise Server, the setup application also installs two BlackBerry Attachment Connector
instances automatically. One of the BlackBerry Attachment Connector instances connects the BlackBerry Enterprise
Server to the BlackBerry Attachment Service. The other instance connects the BlackBerry MDS Connection Service to the
BlackBerry Attachment Service. During the installation process, the setup application gives both BlackBerry Attachment
Connector instances a name that includes the computer name (for example, <computer_name>_AC).
The BlackBerry Administration Service displays the names of both the BlackBerry Attachment Connector instances. By
default, you cannot determine easily which instance connects to the BlackBerry Enterprise Server or the BlackBerry MDS
Connection Service, so you can change the display names of both the BlackBerry Attachment Connector instances to
make them easier to identify.
1. In the BlackBerry Administration Service, on the Servers and components menu, expand BlackBerry Solution
topology > BlackBerry Domain > Component view > Attachment > Connector.
2. Click one of the BlackBerry Attachment Connector instances.
3. On the Instance information tab, locate either the MDS Connection Service Instance name section or the Email
(Exchange) Instance name section. Consider the following naming conventions:
• If you locate the section that is named MDS Connection Service Instance name, the BlackBerry MDS Connection
Service connects to this BlackBerry Attachment Connector instance.
• If you locate the section that is named Email (Exchange) Instance name, the BlackBerry Enterprise Server
connects to this BlackBerry Attachment Connector instance.
4. Click Edit instance.
5. Perform one of the following actions:
• If the BlackBerry MDS Connection Service connects to the BlackBerry Attachment Connector instance, in the
Instance information section, in the Friendly description field, type a unique name (for example,
<server_name>_AC_MDSCS).
