Error description

  • The eXtreme Scale mbean (ShardMBean) has a method
    (swapWithPrimary) that allows a replica shard to change roles
    with it's primary shard in another WXS container.   This can be
    used to balance the number of primaries in WXS Containers on the
    occasion where they have become imbalanced.     This APAR is
    intended to add the -swapShardWithPrimary option to the xsadmin
    utility so that the execution of ShardMBean.swapWithPrimary()
    becomes easier for the WXS end-user.

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of WebSphere eXtreme Scale.       *
    ****************************************************************
    * PROBLEM DESCRIPTION: Provide a way to run the                *
    *                      ShardMBean.swapWithPrimary() method     *
    *                      with the xsadmin tool.                  *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    Currently no way exists for users to invoke the
    ShardMBean.swapWithPrimary() mbean method with the xsadmin
    tool.
    Stopping and restarting individual containers within a
    data grid can result in an imbalance of primary and replica
    shards across the containers.  The swapWithPrimary() method
    provides a manual way to rebalance the shards.
    

Problem conclusion

  • The xsadmin tool was updated to include the
    -swapShardWithPrimary
    option.
