Error description
SQLGetData() on LOB columns is called repeatedly () to get the remaining pieces of data until it returns SQL_SUCCESS, signifying that the entire data has been retrieved for this column. This APAR is documenting the fact that under very rare circumstances the SQLGetData() call may return the wrong data length in the pcbValue. The circumstances are very much depending on the sequence in which sizeh of pieces data was previously retrieved and how large an internal CLI buffer was allocated. This problem causes data to be missing within the application. Additionally in this scenario the call returns SQL_SUCCESS while it should have returned SQL_SUCCESS_WITH_INFO to indicate more data exists.
