Error description

  • Error description.
    Example.
    When performing the following set of commands.
    
    SET CHLAUTH('*') TYPE(BLOCKADDR) ADDRLIST('1.2.3.4')
    
    followed by
    
    SET CHLAUTH('*') TYPE(BLOCKADDR) ADDRLIST('1.2.3.4')
    ACTION(REMOVE)
    
    The blockaddr.ini file still contains the following entry.
    
    ChlAuth = Enabled
    Warn = No
    Addr = 1.2.3.4
    

Local fix

  • Edit the blockaddr.ini file manually.
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    MQ 7.5 users using SET CHLAUTH command to remove BLOCKADDR
    channel authentication records.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    A logic omission in the queue manager channel authentication
    management code caused a failure to update the blockaddr.ini
    file when removing BLOCKADDR records.  This meant that the file
    was not updated when the SET CHLAUTH TYPE(BLOCKADDR) ...
    ACTION(REMOVE) command was issued.
    

Problem conclusion

  • The IBM MQ queue manager code was changed so that BLOCKADDR
    records are correctly removed from the blockaddr.ini file when
    the SET CHLAUTH TYPE(BLOCKADDR) ... ACTION(REMOVE) command is
    issued.
