  * USERS AFFECTED: All CICS users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: CICS Task.commit() or Task.rollback()   *
  *                      in a JTA transaction causes an          *
  *                      InvalidRequestException.                *
  ****************************************************************
  CICS Task.commit() and Task.rollback() is disallowed in a JTA
  transaction and an InvalidRequestException is thrown.
  
  With DB2 Connection.commit() or Connection.rollback(), the DB2
  driver is aware that it's running in CICS and asks CICS to
  coordinate by calling Task.commit()/Task.rollback() also
  resulting in an Exception.
  
  Problems also occur when using a Liberty dataSource with a type2
  connection within JTA, specifically when container managed and
  the user is not in control of the user transaction as in the
  case of JSR 352 batch.  If the user application attempts a DB2
  connection close, the exception is thrown.
  

Problem conclusion

Temporary fix

Comments

• Task.java has been changed to ignore a Task.commit or
  Task.rollback when within a JTA transaction. As a result the
  restriction that DB2 JDBC type 2 connectivity is not supported
  for batch persistence is removed.
  
  The 'Liberty features' topic in the CICS Transaction Server for
  z/OS 5.4.0 Knowledge Center will be updated to remove the
  following restriction associated with the batch-1.0 feature:
  
  'DB2 JDBC type 2 connectivity is not supported for batch
  persistence.'
