Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server - Java Persistence API - JPA 2.1 &   *
  *                  EclipseLink                                 *

  * PROBLEM DESCRIPTION: When connecting to a HANA database,     *
  *                      EclipseLink incorrectly                 *
  *                      determines the database platform to     *
  *                      be DB2Platform.                         *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  Connecting to a HANA database, using a driver for HANA
  database, EclipseLink can read the database product name as
  "HDB" with a major version of "2" and confuse this with DB2.
  This causes the incorrect database platform class to be set in
  EclipseLink and incorrect behavior to occur.
  

Problem conclusion

• The fix for this APAR changes the EclipseLink implementation
  and involves an update to the third-party source. See
  https://bugs.eclipse.org/bugs/show_bug.cgi?id=518774
  
  This fix is currently targeted for WebSphere Application
  Server 9.0.5.3 and WebSphere Liberty 19.0.0.11. For
  more information, see 'Recommended Updates for WebSphere
  Application Server':
  http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
  

Temporary fix

• EclipseLink allows the manual setting of the database platform
  via a persistence unit property:
  "eclipselink.target-database".
  
  To properly get HANA as the database platform, set the
  following property in persistence.xml:
  <property name="eclipselink.target-database"
  value="HANAPlatform"/>
