Error description

  • When the customer's applications use Trusted Connection and the
    configuration is client->DB2 Connect(concentrator On)->z/OS V9
    server, unperdictible errors can be hit by the applications. XA
    applications might see trap DB2 Connect.
    V9 DB2 Connect Concentrator is designed to pool a db2agent
    process after 8 continous transactions from an application are
    done, and the db2agent process can then be invoked to serve
    another application. However, when the connection established
    is trusted connection and no switch-user is done, the db2agent
    that is obtained from the pool to serve the second application
    doesn't re-establish connection to z/OS V9. As a result, the
    second application incorrectly inherits the connection
    established by the first application, such as special registry
    variables(CURRENT PATH, CURRENT PRECISION, etc) set on z/OS.
    XA applications could trap db2 connect. The output of SQL
    statements could be unexpected because they're affected by some
    registry variables that are not set in the applications.
