JR50131: Possible delay in invalidating WXS Near Caches when using clearall

APAR status

  • Closed as program error.

Error description

  • All the Data Cache objects are associated to the WCT+?
    dependency ID. When a cache clear is done, the WCT+?
    invalidation ID is fired and the caching backend (Dynacache or
    WXS) removes all the entries in that cache.
    
     For clients using WXS and the Near Cache function, this
    invalidation is not efficient and it can result in a flood of
    pub-sub traffic between the remote WXS grid and the WCS/WAS
    servers
     to invalidate the individual entries in the Near Cache
    

Local fix

  • Cache can be cleared using the Cache Monitor, or for WXS with
    this command: xscmd -c ClearGrid
    

Problem summary

  • Possible delay in invalidating WXS Near Caches when using
    clearall
    

Problem conclusion

  • The DynaCacheInvalidation Job has been improved so for a
    "clearall", the clear() API is used instead of the WCT+?
    invalidation ID.
    

Temporary fix
