APAR status

  • Closed as program error.

Error description

  • This APAR addresses portal having synchronization issues with
    distributed map cache invalidation processing.
    Updates to public pages on a cluster that is under public pages
    read access usage, might lead to updates that are not correctly
    reflected on other cluster nodes.
    This is a portal enablement APAR that does not fix this issue
    completely but prepares code changes in WAS and Portal to
    finally address the issue.
    

Local fix

  • NA
    

Problem summary

  • This APAR addresses portal having synchronization issues with
    distributed map cache invalidation processing.
    Updates to public pages on a cluster that is under public
    pages read access usage, might lead to updates that are not
    correctly reflected on other cluster nodes.
    

Problem conclusion

  • This APAR introduces a new configuration setting for the 'WP
    CacheManagerService'.
    
    New setting:
    
        cacheglobal.asyncInvalidation=true|false (default=false)
    
    Setting
    
        cacheglobal.asyncInvalidation=true
    
    enables the usage of dynacache asynchronous invalidation events
    in portal cache infrastructure.
