Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users of WebSphere MQ 7.0.1 or 7.1.0 who are using the
    Client SupportPac (MQC7/MQC71), who are using an application
    which attempts to make use of XA functionality.
    
    This APAR is not applicable to users of the WebSphere MQ
    Resource Adapter, see APAR IV48023 for details on this
    component.
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows)
    ****************************************************************
    PROBLEM SUMMARY:
    In order to use XA functionality to allow for MQ to participate
    in distributed two-phase transactions, MQ requires certain
    libraries.
    
    When WebSphere MQ 7.0 and 7.1 first shipped, this functionality
    was provided by the WebSphere MQ Extended Transactional Client
    component of the product.
    
    With the announcement of WebSphere MQ V7.5, the WebSphere MQ
    Extended Transactional Client is available for use in all
    client deployments without additional entitlement. This
    includes all supported versions of WebSphere MQ client
    connecting to any supported version of WebSphere MQ queue
    manager.
    
    As part of this announcement, customers using WebSphere MQ
    V7.0.1 and V7.1 gain the benefit of use of the WebSphere MQ
    Extended Transactional Client with no additional entitlement
    required.
    
    For additional information on this, please see the WebSphere MQ
    V7.5 announcement letter:
    
    http://www.ibm.com/common/ssi/cgi-bin/ssialias?infotype=AN&subt
    ype=CA&htmlfid=897/ENUS212-091
    
    
    In order to obtain these XA specific libraries for client
    installations, the MQ Client SupportPacs MQC7/MQC71 was
    required to includes the necessary files.
    

Problem conclusion

  • The WebSphere MQ Client SupportPacs (MQC7 and MQC71)
    installations have been updated so that they now include the
    necessary XA libraries to permit applications to include WMQ in
    distributed transactions.
