File Naming Pattern Considerations

Outbound acknowledgment places the following files in the Gateway outgoing directory:
  • Acknowledgment XML
  • Routing
  • End of file
To name these files, outbound acknowledgment uses a file naming pattern from the transmission definition configuration. Based on the incoming transmission type loaded, the naming pattern uses a substitution algorithm to produce a unique file name for each outbound acknowledgment. Distinct file extensions are added to this name to generate the complete notification file set.

For more information about file naming patterns and using the transmission definitions screens, see Transaction Server User's Guide.

Here is a sample file naming pattern: 
MYBANK.%PT%.R%PID%.D%DTyyyyMMdd%.T%DThhmmssSSS%
The pattern creates a file name that includes the transmission type indicator, receiving point routing ID, and the date and time down to the milliseconds. For a notification having transmission type T, a receiving point routing value of 5555-1234 and occurring on May 29th, 2009 at 1:41:23:497 PM, the file name created is: 
MYBANK.T.R5555-1234.D20090529.T134123497
The file naming pattern does not include the file extension, so outbound acknowledgment adds file extensions to each file it creates. It delivers the following files to Gateway Server.
  • MYBANK.T.R5555-1234.D20090529.T1341.xml
  • MYBANK.T.R5555-1234.D20090529.T1341.rte
  • MYBANK.T.R5555-1234.D20090529.T1341.eof

The XML file contains the outbound acknowledgment in XML format. The RTE file contains the routing information that instructs the Gateway about how to deliver the file to its receiving point. The EOF file is empty and always written last. It is used to signal the other files have been delivered and are ready for processing.

When a second batch (ICL) is processed four minutes later with a transmission type of R and a receiving point routing of 5555-4321, the following files are copied to the Gateway outgoing directory.

  • MYBANK.R.R5555-4321.D20090529.T1345.xml
  • MYBANK.R.R5555-4321.D20090529.T1345.rte
  • MYBANK.R.R5555-4321.D20090529.T1345.eof
