Problem summary

****************************************************************
* USERS AFFECTED:  Users of IBM WebSphere Application Server   *
*                  that use Open JPA with an Oracle or         *
*                  PostgreSQL Database and multi threaded      *
*                  applications.                               *
****************************************************************
* PROBLEM DESCRIPTION: Primary key constraint violated using   *
*                      an Oracle or PostgreSQL sequence to     *
*                      generate ID in multithreaded            *
*                      application.                            *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
In a multi threaded application, sometimes the threads can try
to use the same generated id for entity creation.

Problem conclusion

Two pieces of code have been back ported to fix this problem.
The first was to synchronize a call to execute a query in
NativeJDBCSeq.java so that only one thread would be able to
generate an id at a time.  The second was to alter
AlterJDBCSeq.java to break a call to nextInternal into
multiple steps so that an variable would only be set if the
results from nextInternal are good.

The fix for this APAR is currently targeted for inclusion in
fix packs 6.1.0.29 and 7.0.0.7.  Please refer to the
