IZ63639: HUB TO RTEMS CONNECT FAILS AFTER RTEMS EPHEMERAL ADDR CHANGE

APAR status

• Closed as program error.

Error description

• When the addressing mode of a remote TEMS changes and the HUB
  is not
    re-cycled with the remote TEMS to affect that change, the HUB
  fails
    to communicate back to the remote TEMS for distributed
  requests.  An
    address mode change is defined as the addition or removal of
    EPHEMERAL:Y on the KDE_TRANSPORT statement of the remote TEMS
  config.
  
  Detailed Recreation Procedure:
    Configure a HUB, remote TEMS and one agent reporting to the
  remote
    TEMS.  Configure the remote TEMS with the EPHEMERAL:Y keyword
  on
    the remote TEMS KDE_TRANSPORT environment variable.  Use the
  TEPS
    to distribute a request to the agent connected  to that remote
  TEMS.
    Assure the situation fires and data is seen at the TEPS.
    Reconfigure the remote TEMS by removing the EPHEMERAL:Y
  keyword.
    When restarting the remote TEMS with this addressing mode
  change,
    do NOT re-cycle the HUB.  Perform the TEPS query to the agent
  on
    the remote TEMS.  The query will fail.  The HUB TEMS RAS1 log
  has
    this message assocuated with the TEPS query failure:
    RUL11STM - Remote request communication failed ....
    and the message will contain the old, ephemeral:y address,
    0.0.0.1 for example.
  

Local fix

• Recycle the TEMS
  

Problem summary

• When the addressing mode of a remote management server changes
  and the HUB management server is not re-cycled with the remote
  management server to affect that change, the HUB management
  server may fail to communicate back to the remote management
  server for distributed requests.
  
  The following message may appear in the management server RAS1
  trace log:
  
     RUL11STM - Remote request communication failed ....
  

Problem conclusion

• The problem occurs because the HUB management server retains the
  addressing information related to the remote management server
  until the HUB management server is recycled.
  
  The communication code has been altered to cause the old address
  information associated with the remote management server to be
  removed from the HUB management server.
  
  
  The fix for this APAR is included in the following maintenance
  vehicle:
      | fix pack | 6.2.1-TIV-ITM-FP0002
      | fix pack | 6.2.2-TIV-ITM-FP0002
  

Temporary fix

• Recycle the HUB management server.
