APAR status

  • Closed as program error.

Error description

  • The customised stitcher, ReplaceDisplayLabel, directly accesses
    an external database to retrieve the info used for the display
    label. That data is formatted and added to the scratchTopology
    data.
    
    Following a database disconnection, the connection from the
    stitcher code is not successfully re-established.
    
    It also occurs only in some circumstances - simply disconnecting
    and reconnecting the DB server does not necessarily generate a
    problem, whereas restarting the DB2 server process (dbstop
    force; db2start) reliably causes a failure

    * RECOMMENDATION:                                              *
    * From ITNM 3.9, the reconnection is automatically handled for *
    * all database connections. In 3.8 it had to be explicitly     *
    * hard-coded for each connection.                              *
    * | fix pack | 3.8.0-ITNMIP-FP0007                             *
    ****************************************************************
    

Problem conclusion

  • Added the standard 3.8 DB reconnection steps to the discovery
    stitcher library. From 3.9, this is already done within the db
    library.
