  • Closed as program error.

Error description

  • Catalog navigation commands that show a list of packages related
    to the object (like the K line command on the table), can cause
    performance issues on systems with a large number of packages.
    This is due to an unoptimized SELECT query.

    * USERS AFFECTED: Users of Db2 Administration Tool for z/OS    *
    ****************************************************************
    * PROBLEM DESCRIPTION: Performance and consistency issues      *
    *                      occur when using catalog navigation     *
    *                      for packages.                           *
    ****************************************************************
    An unoptimized SQL query is used in catalog navigation to get
    the list of packages that depend on the selected object. This
    query results in a longer response time for some line commands
    that display the ADB21K (Packages) catalog navigation panel.
    
    Also, using line commands to navigate between the ADB21K panel
    and other object panels multiple times might result in
    inconsistent results for packages.
