PM96515: REDUCE PERFORMANCE IMPACT WHEN LARGE NUMBER OF LIBRARIES ARE CON FIGURED IN THE AUTHORING PORTLET

 

APAR status

  • Closed as program error.

Error description

  • In WCM environments that have many libraries (50+) it is
    possible to configure the WCM Authoring Portlet to allow users
    with the appropriate access to explore all of these available
    libraries.
    
    As the number of libraries available through the
    authoring portlet increases the impact of processing the access
    rights authoring capability increases increasing page rendering
    times.
    
    Typically the security checks and existence checks to
    determine the set of available libraries is cached and causes
    minimal impact to a request, but if the caches are cleared or
    items have yet to be cached then the impact to request
    performance can be noticeable.
    

Local fix

  • Reduce the number of available configured libraries within the
    Authoring portlet at any given instance.
    

Problem summary

  • In WCM environments that have many libraries (50+) it is
    possible to configure the WCM Authoring Portlet to allow users
    with the appropriate access to explore all of these available
    libraries.
    
    As the number of libraries available through the authoring
    portlet increases the impact of processing the access
    rights authoring capability increases increasing page rendering
    times.
    
    Typically the security checks and existence checks to determine
    the set of available libraries is cached and causes minimal
    impact to a request, but if the caches are cleared or items have
    yet to be cached then the impact to request performance can be
    noticeable.
    

Problem conclusion

  • To minimise the impact of configuring an authoring portlet to
    have a large number of available libraries the algorithm
    determining user rights to authoring capability has been
    optimised to reduce unnecessary access checking against all
    available libraries.
    

Temporary fix
