PM97266: ABENDAEIP CONNECTION_CLOSED IS RETURNED IF SERVER CLOSE THE CONNECTION AND CONNECTION POOLING IS USED.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• HTTP outbound connection pooling is used. When the server
  normally closes the connection ( for a time-out, for example),
  the application receives an ABENDAEIP, INVREQ
  CONNECTION-CLOSED, on the EXEC CICS WEB CONVERSE.
  Also abendAEIQ can happen if the close from the server arrives
  in a different stage of the converse flow.
  In this circumstance CICS must close the socket and either get a
  new socket out of the pool or create a new socket for the
  application, transparently, without any abend.
  .
  .
  The same implementation works fine if connection pooling is not
  used, and a new socked is acquired each time a request comes in.
  .
  The same problem can occur when using INVOKE SERVICE or
  INVOKE WEBSERVICE commands.  These commands will return
  RESP=16 and RESP2=41.
  

Local fix

• code CLOSESTATUS(CLOSE) in the WEBCONVERSE

  ****************************************************************
  CICS is using the outbound HTTP connection pooling support
  introduced at this release.In application, after WEB CLOSE
  API. The socket used will be put socket pool. By any reason,
  socket is closed by remote side, the socket is still left in
  pool. The next time application run WEB OPEN api. The socket
  saved in pool is chosen again. The routine which decide if
  socket is closed can not work as expected. So the closed
  socket is chosen again and used by later WEB CONVERSE api.
  The closed socket is detected by this api and AEIP abend is
  issued which means connection closed.
  

Problem conclusion

• DFHSOUS has been changed to in routine is_dead which is used to
  detect the status of connection.
