The BlackBerry Attachment Service accesses the DOM to process the requests. If users send requests to view the same message attachment again, the BlackBerry Attachment Serviceaccesses the same DOM to process the requests. The BlackBerry Attachment Service keeps all of the cached data in memory only and never caches the original documents. Each attachment conversion process allocates memory when it starts, uses memory on conversion, and caches the attachment DOM locally on the computer that hosts the BlackBerry Attachment Service. A larger cache size means that more memory is allocated to each running conversion process. The maximum file size of attachments impacts the amount of cached memory that the BlackBerry Attachment Service uses. By default, the BlackBerry Attachment Service does not limit the file size of an attachment that is embedded in an email message or retrieved using a link. The BlackBerry Enterprise Server sends data to BlackBerry devices over the wireless network in packets that are no larger than 64 KB, and it can send an unlimited number of packets to BlackBerry devices. You can change how the BlackBerry Attachment Service converts attachments by specifying a maximum file size for attachments that users can receive and controlling how the BlackBerry Attachment Service retrieves, distills, and converts attachment data. Change how a BlackBerry Attachment Service converts attachments 1. In the BlackBerry® Administration Service, on the Servers and components menu, expand BlackBerry Solution topology > BlackBerry Domain > Component view > Attachment > Server. 2. Click the instance that you want to change. 3. Click Edit instance. 4. In the General section, configure the BlackBerry Attachment Service optimization settings. 5. Click Save. 305

Changing how a BlackBerry Attachment Service converts
attachments
If the BlackBerry® Enterprise Server receives requests from BlackBerry device users to view email message
attachments, the BlackBerry Attachment Service converts the attachments into a DOM and caches the DOM locally.
The BlackBerry Attachment Service accesses the DOM to process the requests. If users send requests to view the
same message attachment again, the BlackBerry Attachment Service accesses the same DOM to process the requests.
The BlackBerry Attachment Service keeps all of the cached data in memory only and never caches the original
documents.
Each attachment conversion process allocates memory when it starts, uses memory on conversion, and caches the
attachment DOM locally on the computer that hosts the BlackBerry Attachment Service. A larger cache size means
that more memory is allocated to each running conversion process. The maximum file size of attachments impacts
the amount of cached memory that the BlackBerry Attachment Service uses.
By default, the BlackBerry Attachment Service does not limit the file size of an attachment that is embedded in an
email message or retrieved using a link. The BlackBerry Enterprise Server sends data to BlackBerry devices over the
wireless network in packets that are no larger than 64 KB, and it can send an unlimited number of packets to BlackBerry
devices.
You can change how the BlackBerry Attachment Service converts attachments by specifying a maximum file size for
attachments that users can receive and controlling how the BlackBerry Attachment Service retrieves, distills, and
converts attachment data.
