PH45134: CWSIJ0047E THROWN AFTER CONNECTION TO MESSAGING ENGINE IS REPLACED

APAR status

• Closed as program error.

Error description

• The JCA connection pool contains connections to several
  different messaging engines. SIB detects that two connections
  for different messaging engines are being used in the same
  transaction and replaces one of them. The message ordering is
  then being enforced for the connection that is being replaced so
  that several sessions can be used consistently within a JCA
  container. Since the connection no longer exists, "CWSIJ0047E:
  An operation was attempted on a connection that is already
  closed" is thrown.
