Error description

• When SRCSSID=TRGSSID CAF connection is choosen instead of TCPIP
  and there is no way to force a TCPIP connection to the remote
  target DB2.
  
  When there are two DB2 subsystems with the same subsystem name
  and one is CAF connected and the other TCPIP connected, CT-TS
  assumes that the is only one subsystem. The CAF connection works
  and is used for the source and target subsystems.  This
  enhancement  allows the target to be connected using TCPIP when
  the subsystems names are the same.
  
  A new command SET REMOTE-CONNECT-TYPE(C|D|T) is available for
  this specification where  C=CAF, D=DDF and T=TCPIP.
  Specifying T indicates that the same named subsystem for the
  source and target is two different subsystems.
  
  If no SET command is specified, the normal C, D, T connection
  progression is used.
  
  Note that this command is now the preferred way to specify all
  DDF and TCPIP connections, not just when the two subsystems have
  the same name.  For example, if TCPIP is used and DDF fails,
  error messages are printed for the DDF failure. If  SET
  REMOTE-CONNECT-TYPE(T) then DDF is not attempted and thus there
  are no error messages.

  Code has been changed to correct this condition.
  When there are two DB2 subsystems with the same subsystem name
  and one is CAF connected and the other TCPIP connected, CT-TS
  assumes that the is only one subsystem. The CAF connection works
  and is used for the source and target subsystems.  This
  enhancement  allows the target to be connected using TCPIP when
  the subsystems names are the same.
