Error description

  • Products and items are imported via WebSphere Commerce BOD
    Services into the database, but without category or
    category-relations.  Using the Management Center products are
    distributed to the categories, which are maintained in
    Management Center only.  On maintaining the sales catalogs,
    products are related to the categories, and WebSphere Commerce
    automatically relates the items as well to the categories.
    Having for example 50 products in a category, and 10 items per
    product then there are 550 CATGPENREL records for this category.
     Furthermore, the customer can use a catalog filter to define
    which products can be purchased under which contracts.  If the
    customer only adds products, but not the corresponding items to
    the catalog filters, then the items are not filtered.  When the
    CategoryDisplay URL command is called, the CategoryDataBean is
    used and this CategoryDataBean has an issue when accessing
    products.  The  CategoryDataBean.getProducts() method
    pre-fetches all catalog entries for the category, including all
    the items.  Note, that items are not filtered, because only
    products are contained in the contracts and catalog filters.
    Thus when there are many items in the category, calling the
    getProducts() method can lead to an out of memory condition.
    

Local fix

Problem summary

  • USERS AFFECTED:
    WebSphere Commerce customers who use the
    CategoryDataBean.getProducts() method without also using the
    getItems() method.
    
    PROBLEM ABSTRACT:
    CategoryDataBean pre-fetching of item catalog entries can result
    in an out of memory condition.
    
    BUSINESS IMPACT:
    Out of memory crash due to CatalogDataBean retrieving all
    catalog data.
    
    RECOMMENDATION:
    

Problem conclusion

  • The CategoryDataBean.getProducts() method was changed to not
    pre-fetch items, and the getItems() method was changed to
    not-pre-fetch  products and other kinds of catalog entries.
