If you intend to use the Document Conversion Service from a SharePoint
environment, then it is recommended to configure security as per the previous
table.
This will restrict use to members of the standard SharePoint wss_wpg and
wss_admin_wpg groups. These groups, however, are local to the SharePoint
machine, which may cause problems if the Document Conversion Service is
installed on a separate system that does not have these local groups.
The solution is to either manually create these groups on the server hosting
the Document Converter, and populate them with the same users as on the
SharePoint servers, or to change the name of the groups in the config file.
If there is no need to restrict access to the back end of the Document
Converter Service then you may want to consider changing the group names
to ‘
NT AUTHORITY\authenticated users
’.
The authenticated users group allows any user with a valid login account to
connect. Note that this is not the same as anonymous access.
Keep in mind that SharePoint connects to the Document Conversion service
using the Web Application’s
application pool
account, not the user’s account.
2.6.2.2
Concurrency
The Document Converter allows multiple operations to be processed
simultaneously. The default settings are sufficient for most situations, but if
you are running the service on a standalone server or if you expect the
majority of your conversions to be for a single specific format then you may
want to tune the concurrency settings.
The following settings can be changed in the config file.
serviceThrottling maxConcurrentCalls: This setting represents the
maximum number of concurrent requests that can be executed across all
operations before new requests are queued. Be careful when lowering the
default value when using the product to convert InfoPath forms with
attachments, or MSG files, as this may result in a deadlock situation.
Please note that this number includes any requests for applying
watermarks or Security on documents that are already in PDF format and
don’t require conversion.
Concurrency.MaximumInstances.WinWord: The maximum number of
concurrent MS-Word conversion requests before new requests are
queued. This value defaults to 2.
Concurrency.MaximumInstances.Excel: The maximum number of
concurrent Excel conversion requests before new requests are queued.
This value defaults to 2.
Concurrency.MaximumInstances.Visio: The maximum number of
concurrent Visio / Vector conversion requests before new requests are
queued. This value defaults to 2.
Concurrency.MaximumInstances.CAD: The maximum number of
concurrent AutoCAD conversion requests before new requests are
queued. This value defaults to 2.
