Create a BlackBerry Attachment Service
pool for high availability
During the BlackBerry Attachment Service installation process, the setup application writes data about the BlackBerry
Attachment Service instance to the BlackBerry Configuration Database. You can create a BlackBerry Attachment Service
pool for each BlackBerry Enterprise Server by associating multiple BlackBerry Attachment Service instances with each
BlackBerry Enterprise Server. Within each pool, you can create primary and secondary groups.
For more information, see the BlackBerry Enterprise Server Planning Guide.
1. In the BlackBerry Administration Service, on the Servers and components menu, expand BlackBerry Solution
topology > BlackBerry Domain > Component view > Attachment > Connector.
2. Click the BlackBerry Attachment Connector that you installed with the BlackBerry Enterprise Server that you want to
create the BlackBerry Attachment Service pool for. By default, the name of the BlackBerry Attachment Connector is
<computername>_EMAIL_AC_13.
3. Click Edit instance.
4. On the Supported Attachment Server Instances tab, in the Name drop-down list, click the instance that you want to
add.
5. In the Results Query Period(s) field, type the number of seconds that you want the BlackBerry Enterprise Server to
wait for a response before it sends the request to another BlackBerry Attachment Service instance.
6. In the Dedicated Server drop-down list, click yes if you want the BlackBerry Attachment Service instance to process
only specific content types for the BlackBerry Enterprise Server.
7. In the Pool drop-down list, complete one of the following actions:
• To include the BlackBerry Attachment Service instance in the primary group of instances within a pool, click
Primary.
• To include the BlackBerry Attachment Service instance in the secondary group, click Secondary.
8. Complete the following actions:
• To turn on support for an attachment file format, in the Extensions section, type the file extension of the format.
Click the Add icon that is located beside the extension that you typed.
• To turn off support for an attachment file format, in the Extensions section, click the Delete icon that is located
beside the file extension.
9. Click the Add icon.
10. Repeat steps 5 to 9 for each BlackBerry Attachment Service instance that you want to add to the pool.
