Problem conclusion

  • RESOLUTION SUMMARY:
    
    A code fix is provided.
    
    As part of addressing this issue, we have created two new BPML
    parameters for the Crypto Message Service.
    
    1. pipeSize -     Size of the pipe (in bytes) created for
    carrying out the pipeline activities.
                             Defaults to a value of 4096.
                             Optional.
                             Allowed values - any valid non-negative
    integer values
                             NOTE :-
                                           1. The pipeSize value
    should always be greater than the bufferSize value.
                                           2. This parameter shall
    be used only when dealing with large MIME headers where the
    header size is > 1024 bytes.
    
    
    2. bufferSize -     Size of the buffer(in bytes) to hold the
    incoming data.
                               Defaults to a value of 1024.
                               Optional.
                               Allowed values - any valid
    non-negative integer values
                               NOTE :-
                                             1. The pipeSize value
    should always be greater than the bufferSize value.
                                             2. This parameter shall
    be used only when dealing with large MIME headers where the
    header size is > 1024 bytes.
