I read the following: Is this on 11g? I was not able to find in our in channel details on 11g. The only on i found was Is Van Mailbox?No. AFAIK, this feature is not yet available in 11g. You may log a SR with support.
VAN will not give permission to Delete files. It marks the files when they get picked up. They will not allow us to dictate the information on there services.B2B 11g cannot poll a directory with read-only user, as of now. As a workaround, you may have a simple shell script which should download messages from FTP server to your local B2B server directory and then configure B2B with File listening channel to poll the files from local directory.
