Transfer sites

A transfer site is a location such as a local folder or protocol server used when sending or receiving files during a server-initiated transfer. SecureTransport comes with pre-built transfer sites for file transfers based on AS2, Folder Monitor, FTP(S), Generic-HTTP(S), HTTP(S), PeSIT, SSH (SFTP), and System to Human. Support for other transfer protocols can be added using connectors. See Pluggable Transfer Sites.

Transfer sites are specified and managed on a per-account basis. When defining a transfer site as part of an account, you need to provide the information required for connecting to the site, authentication and sending or receiving files. The transfer protocol you select dictates the information required in the transfer site configuration.

In general, a site is used for server-initiated or AS2 transfers. In the case of a server-initiated transfer, a file is either uploaded to the site (when a subscription processes an uploaded file) or downloaded from the site using a schedule in a subscription.

An account can have zero or more transfer sites. An account can subscribe to zero or more applications, and an application can be triggered when a file is transferred using a site.

Common properties for all transfer sites

A transfer site in SecureTransport is defined with various properties. To avoid repetition, the common properties for all Transfer Sites are briefly described here. Properties which are custom to each Transfer Site are described in the dedicated for each available transfer site type (scroll to the bottom of this page).

  • Site Name – the name of the site. This name must be unique for the account.
  • You cannot enter spaces-only values in the Site Name field.
  • Site Type – indicates whether transfers are internal (within a single organization) or partner (between organizations). Reported to Axway Sentinel as USERPARAMETER1 and displayed in the Sentinel event attributes.
  • Access Level - transfer site access level determines whether and which other accounts could reuse this transfer site in the Send To Partner step.
    • Private – The access level is private. Only the current account is able to use this transfer site.
    • Business Unit – Access to the transfer site is limited to the account's business unit. The current account and all accounts in the current account’s business unit can use this transfer site.
    • Public – Access to the transfer site is public. All accounts are able use this transfer site.
      • NoteAccess level is applicable only when Advanced Routing feature is used. For more information see Advanced Routing.
  • Maximum parallel transfers – If you enter a value greater than zero, SecureTransport executes only the specified number of transfers in parallel. If the value is null or zero, the maximum number of parallel transfers is limited by system capacity.
  • The maximum number of parallel transfers limit is applied cluster wide. The limit for files transferred from the client will not be exceeded. Due to limitations in Standard Cluster communication mode, the parallel pulls limit can be exceeded when there are several connections. If you want to force the limit, then the force.standard.cluster.sit.transfers.sync=true system property should be added to the start_tm_console. Adding the property to the start_tm_console has a performance penalty due to increased cluster communication.
    Note that the force.standard.cluster.sit.transfers.sync value overrides the value of the force.standart.cluster.sit.pulls.sync property, used in previous SecureTransport versions for the same purposes.
    You can configure Maximum parallel transfers with the following Transfer site protocols: AS2, FTP(S), HTTP(S), SSH, Generic-HTTP(S), SharePoint.
    NoteWhen multiple transfer limitations are set, all of them apply but the strictest limitation takes priority over the rest. The following limitations may affect server initiated transfers:
    • Maximum Parallel Transfers - the limit per Transfer Site, described here.
    • Maximum number of parallel transfers - the limit for "Files Received from this Account or its Partners", specified in Basic Application or Advanced Routing Subscriptions
    • Maximum concurrent connections per host for outbound connections
  • Use Expression Language - when checked, all possible checkboxes for boolean properties are switched to text fields. Applicable for Folder Monitor, FTP(S), HTTP(S), SSH (SFTP) and PeSIT Transfer Sites. In these text fields, you can type values or expressions for the required and the optional fields needed to define the transfer site.
    You can use expressions in the fields indicated by a vertical yellow bar.
  • Transfer Protocol – one of the supported protocols: AS2, Connect:Direct, Folder Monitor, FTP(S), HTTP(S), SSH (SFTP), PeSIT, System to Human, or a protocol implemented using the file services interface. The protocol of an existing transfer site cannot be changed.
  • Additional attributes – a group of fields that allows you to add (or remove) custom attributes as attribute:value pairs to use with your Transfer sites. This functionality is available at the bottom of the page on the Add Transfer Site page, regardless of the Transfer site type. See Additional attributes.
  • Custom properties – these vary according to the selected transfer protocol. For more information about each protocol, see the respective subtopic:
