  * PROBLEM DESCRIPTION:                                         *
  * The APREUSE bind option is sometimes                         *
  * unable to reuse a particular access                          *
  * path due to a change in the query                            *
  * transformations performed on the                             *
  * query.                                                       *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * Apply corrective PTF when available                          *
  ****************************************************************
  When certain query transformations applied to a query change,
  it sometimes results in the APREUSE bind option being unable to
  reuse the access path.
  This can result in a bind error, when APREUSE(ERROR) is
  specified, or a bind warning, when APREUSE(WARN) is specified.
  

Problem conclusion

• This APAR provides new functionality to improve the reusability
  of certain access paths with the APREUSE bind option when query
  transformations are involved.
  This reduces the likelihood that the APREUSE bind option will
  result in a bind error, or a bind warning.
