The Filter Process Model

By default, Filter runs independently from the calling application process. This is called out-of-process filtering. Out-of-process filtering protects the stability of the calling application in the rare case when a malformed document causes Filter to fail. You can configure Filter to run in the same process as the calling application. This is called in-process filtering. However, OpenText strongly recommends that you run Filter out of process whenever possible.

To monitor and debug filtering operations during out-of-process filtering, you can generate an error log at run time. See Generate an Error Log.
