Error description

  • After configuring a WebSphere MQ File Transfer Edition agent
    with the following property:
    
      enableMemoryAllocationChecking=true
    
    some managed transfers entered recovery processing.  When this
    occurred, an FFDC file was generated with following details:
    
      Class:      com.ibm.wmqfte.statestore.impl.FTEStateStoreImpl
      Method:     recoverSenderTransfer
      Probe:      FFDC_025

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects users of WebSphere MQ File Transfer Edition
    v7.0.4 and WebSphere MQ Managed File Transfer v7.5
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    When using WebSphere MQ File Transfer Edition (FTE) V7.0.4 or
    WebSphere MQ Managed File Transfer v7.5, an agent may put a
    managed transfer into a "ResumingTransfer" state.  A managed
    transfer can enter this state at the source agent when the agent
    receives a resynchronization request message from the partner,
    destination agent.  The managed transfer is then scheduled for
    restart.  If the managed transfer could not be restarted by the
    source agent, then the agent attempted to move it to a
    "Recovering" transfer state.  However, the source agent did not
    contain a valid mapping that would allow the transfer state to
    be moved from "Resuming" to "Recovering" and, as such, an FFDC
    was generated.
    

Problem conclusion

  • The WebSphere MQ File Transfer Edition product code has been
    updated such that a source agent has a valid mapping that allows
    it to move a managed transfer from "Resuming" state to
    "Recovering" state, preventing an FFDC from being generated.
