Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All * **************************************************************** * PROBLEM DESCRIPTION: TCPIPSERVICE closed after message * * DFHSO0114 is incorrectly displayed. * **************************************************************** * RECOMMENDATION: * **************************************************************** The sockets listener task ( CSOL ) attaches a CICS web receiver task ( CWXN ) in response to a new connection from an HTTP client. CWXN runs immediately and encounters an error as the client has closed the connection. CWXN terminates and dissociates itself from the CICS socket object before CSOL relinquishes its reserve on the socket. When CSOL relinquishes its reserve, there are no other CICS tasks referencing the socket. As no socket receive is in progress the doclose flag is set indicating that the client socket should be closed. . The doclose flag causes CSOL to assume that there is a basic problem with the TCPIPSERVICE environment so it then closes the TCPIPSERVICE. This action is inappropriate in these circumstances. ADDITIONAL KEYWORDS : MSGDFHSO0114 DFHSO0108 MSGDFHSO0108
Problem conclusion
DFHSOLS has been changed so that it no longer attempts to close the TCPIPSERVICE just because it has been told to close a newly connected client socket.
