APAR status

  • Closed as program error.

Error description

  • Probe PU522020 may be generated during broker startup or a
    Probe PU522010 or SIGSEGV will be generated during
    publish/subscribe.
    

Local fix

  • 1)  Until we provide a fix, please remove   iseries qmgr from
    other linux qmgr machines from the broker topology
    2)   Remove the messages from
    'SYSTEM.BROKER.INTER.BROKER.COMMUNICATIONS' with correlid prefix
     C1D4D8E8)
    3) issue clrmqbrk
    .
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users running broker in a mixed OS environment where the
    character set of one OS differs from other. The operating
    systems like AS400 uses EBCDIC whereas UNIX/LINUX/WINDOWS uses
    ASCII character set.
    
    Platforms affected:
     All Distributed (iSeries, all Unix and Windows)
    ****************************************************************
    PROBLEM SUMMARY:
    1. The pub/sub broker fails to start when different types of
    control messages(ASCII AND EBCDIC) are exchanged between
    brokers. This problem occurs when the broker receives control
    message in non-native character set. Operating systems like
    AS400 use EBCDIC whereas UNIX/LINUX/WINDOWS use the ASCII
    character set. Typically Probe PU522020 will be generated for
    this problem.
    
    2. When an AS400 broker extracts the request type from the
    control message, the request might be converted to an invalid
    value. Typically Probe PU522010 or SIGSEGV will be generated
    for this problem.
    

Problem conclusion

  • 1. Control message processing has been modified to support
    both ASCII and EBCDIC control messages.
    2. Appropriate code changes have been made to correct the
    invalid request type or the SIGSEGV.
