  The ABEND04E RC00E70005 DSNNXML.DSNNOLCK:M210 can occur when
  running a SELECT statement with an XML column on the select
  list.  The problem is caused by PTF UK69778. For the problem
  to occur these conditions must be met:
  
   1) The XML column is a stand alone expression on the select
      list.
   2) The XML column supports multiple XML versions.
   3) The isolation level is UR, Uncommitted reader.
   4) The SELECT statement is running in a distributed unit
      of work.
  
  The ABEND04E RC00E70005 DSNNXML.DSNNOLCK:M210 occurred
  because no XML lock was held for the XML column running
  with isolation level UR.  With PTF UK69778, the logic was
  improved to avoid holding on to the XML lock when the
  isolation level is UR and the XML column supports multiple
  XML versions.  The logic in DSNNOLCK needed to be changed
  to tolerate this case.
  

Problem conclusion

• DSNNOLCK was fixed to tolerate the XML lock not being held
  when the isolation level is UR and the XML column supports
  multiple XML versions.
