Error description

  • When creating a transfer based off a previously created xml
    using the -td (transfer definition file) and -tb (time base)
    parameters, where -tb is set to "UTC", the following time
    schedule  format is created:
    
    <submit timebase="UTC"
    timezone="America/New_York">YYYY-MM-DDTXX:XX+0000</submit>.
    
    This is correct for a UTC time base because it is +0000.
    
    When it is actually scheduled on the agent the time is correct.
    
    If the agent stops and starts again, the scheduled transfer
    changes to:
    <submit timebase="UTC"
    timezone="America/New_York">YYYY-MM-DDTXX:XX-0400</submit>
    
    The timezone information is incorrect, as the time base was
    originally set to be UTC
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This affects users of IBM MQ Managed File Transfer who have
    agents that process scheduled transfers, where the scheduled
    transfers are created with a time base of UTC.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    When a scheduled transfer is created, the agent stores the
    details of that transfer in a message on the
    SYSTEM.FTE.EVENT.<agent name> queue. If the agent is restarted
    while the scheduled transfer is still active, then the agent
    will use the information in the message to rebuild the scheduled
    transfer.
    
    When the agent rebuilt a scheduled transfer after it was
    restarted, the timezone information in the message on the
    SYSTEM.FTE.EVENT.<agent name> queue was ignored - the scheduled
    transfer was recreated using the local timezone of the agent. As
    a result, if the scheduled transfer was originally created with
    a time base of UTC, it would run at an unexpected time.
    

Problem conclusion

  • To resolve this issue, agents will now read the timezone
    information contained in the message on the
    SYSTEM.FTE.EVENT.<agent name> queue when rebuilding scheduled
    transfers following a restart. As a result, scheduled transfers
    will continue to run at the expected time after an agent is
    restarted.
