Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server  using cache replication and cache   *
    *                  aliases.                                    *
    ****************************************************************
    * PROBLEM DESCRIPTION: Aliases added to a cache instance may   *
    *                      not be replicated to other              *
    *                      application servers.                    *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    If an alias is added to the cache after the original cache
    entry is created the alias may not be replicated.
    

Problem conclusion

  • A new JVM custom property is being introduced to always
    replicate cache aliases.
    
    From the WebSphere administrative console, click Servers >
    Server Types, and WebSphere application servers >
    server_name . Then, under Server Infrastructure, click Java and
    process management > Process definition > Java virtual machine
    > Custom properties.  Add property
    com.ibm.ws.cache.CacheConfig.replicateAliasEntries with a
    value of true.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 7.0.0.45, 8.0.0.14, 8.5.5.13 and 9.0.0.5.  Please
