Error description

  • The WebSphere Commerce Sales Center normally caches customer
    related information in the Dynamic Cache facility, and issues
    customer related invalidation messages to DynaCache when the
    customer related information changes in the database.  When the
    Sales Center is not frequently used, while customer related
    information does frequently change in the database, the
    occasional performance benefits of Sales Center caching may be
    less than the constant slight performance degradation resulting
    from frequent processing of the invalidation messages.

Problem summary

  • USERS AFFECTED:
     WebSphere Commerce users on Version 7.0
    
     PROBLEM ABSTRACT:
     How to turn off Sales Center customer related caching and its
    associated invalidation messages.
    
     BUSINESS IMPACT:
     Slight performance degradation due to frequent processing of
    Sales Center customer related cache invalidation messages.
    
     RECOMMENDATION:
    

Problem conclusion

  • fix adds a new wc-server.xml customization tag in the
    InstanceProperties tag.  Add the new tag just after the opening
    InstanceProperties tag, like this:
    
     <InstanceProperties name="Instance Properties">
    
    <com.ibm.commerce.telesales.messaging.bodreply.ShowCustomerCache
    CmdImpl enabled="false"/>
    
     When enabled="false", the ShowCustomerCacheCmdImpl command sets
    its cache expiry to the current time, thus immediately
    invalidating its cache entry, and effectively disabling caching
    for that command.
    
     The commands that normally issue the "Customers" invalidation
    to the baseCache have been changed to not issue it when
    enabled="false".
