Obtain the fix for this APAR.

APAR status

• Closed as program error.

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
  74610296
  
  
  
  
  
  
  
  
  Additional Symptom(s) Search Keyword(s): HealthChecker health
  checker
  

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.
