Configuring the FTP BC WSDL for Clustering

The FTP BC has no runtime configuration requirements for clustering, but there are a few requirements and options for configuring the properties in any FTP BC WSDL documents deployed to the cluster. These options assist with concurrency issues and load balancing

To ensure that output files are not overwritten by concurrent threads, you can specify a pattern for the output message name using either %u or %seq_name to keep all file names unique.

To Configure the FTP BC WSDL for Clustering

1. For outbound messages, do the following:

   1. In the FTP BC WSDL document, scroll to the input message definition under Bindings (named ftp:message or ftp:transfer, by default).

   2. Select ftp:message or ftp:transfer.

      The Properties panel displays the properties for the message.

   3. Do one of the following:

      • For ftp:message, modify the messageName property to use a unique pattern.

        Use either %u to assign a unique UUID number to each output file, or %seq_name for persisted sequence number creation.

        For example, output%u.txt.

      • For ftp:transfer, modify the sendTo property to use a unique pattern.

        Use the same patterns as described above.

      Note –

      Do not use %d in the file name because files might be overwritten.

   4. Save and close the WSDL file.

2. To define a directory where recovery logs, malformed messages, and so on are stored, set the ftp:address/@baseLocation WSDL attribute to the full path.
