Delay Mirth message delivery

I am interfacing with a system which schedules appointments. The destination system does not allow appointments to be scheduled more than 30 days in advance, but the source system may send the appointment at any time (frequently beyond 30 days). How can I delay the delivery of the message till it is within the 30d window?

Solution

  • Create two channels. Have the first write the file to disk and set the "lastWriteTime" to the date you would like the message to be delivered. The second channel should read from this directory and use the "Check File Time" option to filter only those messages with historical dates.

    Channel 1 destination 1:

    Transformer Javascript:

        channelMap.put('deliverAfter', msg['SCH']['SCH.11']['SCH.11.1'].toString());

    Destination Settings:

    Connector Type: Javascript Writer

        var deliverAfter = DateUtil.getDate('yyyyMMddHHmm', $('deliverAfter'));
    var path = 'c:/data/queue/' + connectorMessage.getMessageId();
    org.apache.commons.io.FileUtils.writeStringToFile(new java.io.File(path), connectorMessage.getEncodedData(), 'UTF-8');
    java.nio.file.Files.setLastModifiedTime(java.nio.file.Paths.get(path), java.nio.file.attribute.FileTime.fromMillis(deliverAfter.getTime()));

    Channel 2:

    Source reader settings:

    Path: c:/data/queue/
    After Processing Action: Delete
    Check File Age: Yes
    File age (ms): 1000
    Encoding: UTF-8
