APAR status

  • Closed as program error.

Error description

  • When using the xa_recover function call from a client-
    connected program, and the client machine uses a native integer
    encoding different from the server, the XIDs are misreported to
    the client by WebSphere MQ. This might lead to transactions
    remaining indoubt, and so requiring manual action to resolve
    them.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of WebSphere MQ as an XA Resource Manager, using an
    external XA Transaction Manager, where the server runs on a
    machine with native integer encoding different from the server.
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows)
    ****************************************************************
    PROBLEM SUMMARY:
    The format ID in the XA transaction identifier (XID) was not
    being sent correctly to the client.  It was being sent in the
    encoding native to the server, which meant it was incorrect when
    being read by the software running on the client.
    

Problem conclusion

  • The format ID has been corrected before sending to the client.
