Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 8 * * Release 0 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: Message ICH408I issued when starting an * * MQ listener with TCPSTACK=SINGLE * **************************************************************** * RECOMMENDATION: * **************************************************************** When starting an MQ TCP/IP listener with TCPSTACK=SINGLE, a TCP/IP socket is opened before the listener TCB has established affinity to the TCP/IP stack named in the TCPNAME parameter. Where access to any additional TCP/IP stacks on the system is prohibited by RACF security controls on the EZB.STACKACCESS.**, EZB.INITSTACK.**, or EZB.** profiles for class SERVAUTH then message ICH408I may be issued. This is caused by the listener TCB failing to set an affinity to the configured TCP/IP stack, prior to opening a socket to test the available protocols.
Problem conclusion
Processing has been amended to ensure that affinity to the TCP/IP stack named in the TCPNAME parameter is established prior to opening a socket. 000Y CSQXRCTL
