Error description

  • There are two bugs here - if you could get a single
    APAR raised to cover both that would be good. I've
    attached a fixed Collector but please still raise an
    APAR.
    
     Bug 1: Is that the XML response from the SAM
    may not always include characters that the XML parser
    we use can parse. This causes the Collector to exit.
       I actually saw this bug at another
    customer and have had the fix waiting for the APAR
    which they never raised (I can't put any code changes
    into older versions without an APAR)
     Bug 2: It turns out that the XML data that
    fails to parse is part of a mass of data that we are
    unintentionally requesting from the SAM.
      The Physical Link download code code
    makes a request for a SAM object but forgets to limit
    the download to the top level object - basically we
    just want the device name but end up downloading ALL
    known data for the device from the SAM.. I assume this
    hasn't been seen before because if only affects one
    type of remote link.
    

Local fix

  • None. L3 has a Test Fix in the following:
    Fixed both of these issues in the
    Alcatel5620SamSoapCollector.pm which you need to copy
    to your $PRECISION_HOME/collectors/perlCollectors/
      Alcatel5620SamSoap dir.

Problem conclusion

  • The Alcatel5620SamSoap Collector has been modified to prevent
    exit when unparsable XML is received (it will print an error
    instead). Also the unparsable XML originated due to an
    unintended full data download from certain devices during
    physical link discovery; this has been fixed too.
