         Welcome to IBM* DB2 Universal Database* (DB2*) Extenders
                             Version 5.2 PTF
 
    This PTF adds new function to and fixes problems in DB2 UDB Extenders
    V5.2 for AIX client and AIX server in a non-partitioned database server
    environment.

    1.0 New Function
    ________________

    A new environment variable, DB2MMCATALOGDELAY, has been added. The
    The environment variable is used to set the time interval, in seconds,
    for QBIC automatic cataloging. The range is 1 through an extremely large 
    number; the default value is 60.

 
    2.0 FIXES
    _________
 

    o If a database connection did not exist, commands issued through the 
      db2ext command-line processor, returned incorrect messages. 

    o The DBiBrowse API and DBaPlay API returned an SQL error code. For  
      example, the QBICDEMO sample program returned this SQL error code when 
      the DBiBrowse API was executed in the program.

    o QBIC administrative APIs sometimes returned SQL error codes and messages
      for a previously executed API. 

    o If the QbQuerySetFeatureData API was specified using a client file as the
      source for feature data, the API failed. For example, if a user specified
      AVERAGE FILE to the QBICDEMO sample program, (this runs an average
      color query based on feature data in a client file), the 
      QbQuerySetFeatureData( ) API in the program failed. 

    o The DBvBuildStoryBoardFile API returned errors such as trap and unable to 
      extract a frame from last scene.

    o The DBvOpen API returned errors such as unknown packet type.
