IT26533: IIB NODE MIGRATED TO V10 FAILS TO START AFTER ENABLED MQTT SERVER FAILS TO CONNECT

APAR status

• Closed as program error.

Error description

• After an in place migration from IIB V9 to IIB V10, an
  Integration Node is unable to start because of a failure
  starting an enabled MQTT Server.
  

Local fix

• Configure a port number for the MQTTServer as follows:
    mqsichangeproperties -b pubsub -o MQTTServer  -n port -v true
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users migrating an existing Integration Node to V10 when an
  MQTT server was previously enabled at the earlier product level.
  
  
  Platforms affected:
  z/OS, MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  When starting the migrated Integration Node which had a MQTT
  server enabled at the earlier level , the following sequence of
  errors may be seen:
  
  BIP9152S: Unable to connect to the MQTT broker owned by node:
  '<Integration Node Name>'
  
  BIP2826E: Integration server termination wait timer reached.
  There are '<number>' threads still executing.
  
  BIP2228E: Severe error:
  /build/S1000_slot1/S1000_P/src/CommonServices/Unix/ImbAbend.cpp
  1318 non-fatal signal received Abend file:
  /var/mqsi/common/errors/TBCOM.agent.12427.1.abend action: abort
  
  It was not possible to shut down the Integration node using the
  mqsistop command, because it will not terminate the biproker and
  bibpservice processes.
  
  It may be necessary to terminate the brokers processes manually
  using the kill -9 system command.
  
  The problem is caused by an incorrect default value for the port
  number of the MQTT server that is set during the migration
  process.
  

Problem conclusion

• The product now automatically starts an embedded MQTT server
  for an Integration Node that has been migrated to V10, and which
  previously ran with an MQTT server enabled.
