Error description

  • HealthChecker fails to create socket when started after TCPIP
    message EZAIN11I. The TCPIP stack being used is also configured
    for ATTLS but the message EZZ4250I AT-TLS SERVICES ARE
    AVAILABLE FOR xxx had not been issued yet. The following
    message is issued by Health Checker when the erro occurs
    EZBH900I INTERNAL ERROR: Function BPX1SOC RC 000 00070 RSN

Local fix

  • Grant read access to the HealthChecker address space for the
    EZB.INITSTACK.sysname.tcpname resource profile in the SERVAUTH
    class or start The HealthChecker address space after message
    EZZ4250I

    ****************************************************************
    z/OS Health Checker fails the initial TCP/IP health checks with
    diag code 00000070_74610296 when TCPCONFIG TTLS is configured.
    
    The TCP/IP stack initialization process detects TCPCONFIG TTLS
    is configured in the profile and blocks access to sockets
    until Pagent has installed the TTLS policy.  The blocking of
    sockets is accompanied by message "EZZ4248E TCPCS2 WAITING FOR
    PAGENT TTLS POLICY".  The stack initialization continues and
    when all core functions are initialized message "EZB6473I
    TCP/IP STACK FUNCTIONS INITIALIZATION COMPLETE" is issued.
    The stack initialization performs an internal Health Checker
    initialization now that the core stack functions are
    available.  Health Checker drives a TCP/IP health checking
    function that opens a socket, however the socket call fails
    if Pagent has not completed the installation of the TTLS
    policy.

Problem conclusion

  • EZBTIINI has been amended to defer the initialization call to
    HealthChecker until Pagent has installed the AT-TLS policy
    when TCPCONFIG TTLS is configured.
