title: xa_open failure with SQLCODE=-1032
body: <p>I am using a Tuxedo(v12.2.2.0.0) on Linux（x64) to access DB2 on mainframe through DB2 Connect Server(v9.7).</p>
  
  <p>Now i meet a problem that the TMS_UDB can not start up。
  From Tuxedo ULOG, it says:</p>
  
  <blockquote>
    <p>ERROR: tpopen TPERMERR xa_open returned XAER_RMERR</p>
  </blockquote>
  
  <p>I checked db2dial log it shows:</p>

  <p>Any DB2 export, how can i make it fixed ? thanks</p>
  
  <p>I have verified DB2 client CONNECT command($ db2 connect to DBXX user USERxx using PASSXX), and query out data using SELECT statement.
  and also have following the Tuxedo guide to set DB2 configuration items.
