  ****************************************************************
  A remote requester (Site1) application connects to a DB2 11
  for z/OS server (Site2) and executes SQL that refers to another
  remote DB2 11 for z/OS (Site3) server.
  The DB2 hopping server (Site2), when generating command data
  for global variables, incorrectly determined that the DB2
  downstream server (Site3) requires the global variable
  command data stream to be encrypted.  As a result, encrypted
  global variable command data is incorrectly generated and sent
  to the DB2 downstream server (Site3).
  When the encrypted global variable data is decrypted by the DB2
  downstream server (Site3), the decrypted form of the global
  variable command data yielded an invalid data stream which
  leads to the DB2 down stream server (Site3) abend.
  The reason for the invalid data stream (after decryption) can't
  be determined.  However, the root cause is that the DB2
  hopping server (Site2) incorrectly determined that the global
  variable data must be encrypted.
   Note: In the reported scenario, the downstream server (Site3)
    does not require the global command data to be encrypted.
  Therefore, this APAR provides a solution on the DB2 hopping
  server (Site2) to correctly determine whether or not the DB2
  downstream server (Site3) requires global variable command
  data to be encrypted.
  

Problem conclusion

• The DB2 hopping server (Site2) is corrected to generate the
  global variable command data stream based on the fields which
  contain accurate DB2 downstream server information.
