Interface NodeHousekeepingMBean

  • public interface NodeHousekeepingMBean

    The NodeHousekeepingMBean MBean interface provides methods for inspecting Rhino SLEE state.

    Methods are provided for locating, inspecting, and in some cases removing Rhino SLEE internal state. These methods are intended to assist in application debugging in addition to preventing downtime caused by unexpected faults in a production system.

    Clients should obtain the ObjectName of a NodeHousekeepingMBean using RhinoHousekeepingMBean.getNodeHousekeeping(int) for a particular node. Operations invoked on a NodeHousekeepingMBean only apply to state visible to that node.

    Timestamps

    Search methods that accept time ranges accept timestamps as long values measured in milliseconds. Because timestamps are considered to be relative to the system time of the Rhino node processing the request some inaccuracy will occur if the system clock’s on client and all cluster nodes are out of sync. In the worst case this simply means too few results may be returned. In all cases where a timestamp parameter is available it is optional and will only be effective if the supplied value is greater than 0.

    Searching and result set sizes

    None of the search type methods in this MBean will return an unlimited number of entries. This is intended to prevent unacceptable system pauses or latency caused by collating and serialising a huge result set. All search type methods take a max parameter which allows the user to limit the result size.

        void cancelRemoteTimer​(String remoteTimerID)
                throws InvalidPKeyException,
                       UnknownTimerException,
                       ManagementException

        Cancel a remote timer.

        This method cancels a remotely armed timer. Cancelling a remote timer prevents the timer from triggering activity adoption by another node in the event that the target node of remote timer event callbacks fails. Cancelling a remote timer does not itself affect any associated local SLEE timer, ie. the local timer will still fire unless it is also cancelled (or it expires).

        This method requires the remote timer’s primary key as returned by getRemoteTimers(int, java.lang.String, long, long).

        Parameters:
        remoteTimerID - encoded remote timer id.
        Throws:
        UnknownTimerException - if no remote timer can be found with the specified primary key - may indicate that the timer has expired or the underlying activity has already ended and all its SLEE state removed.
        InvalidPKeyException - if the remote timer primary key is invalid.
        ManagementException - if a system failure occurs.

                           NameNotBoundException

        Remove an activity context naming facility binding.

        Caution: This method irrevocably removes application state.

        Names bound in the activity context naming facility can be located using getBoundActivities(int, long, long))

        Parameters:
        activityPKey - the bound activity.
        name - the bound name.
        nonResident - boolean flag indicating if activities not currently resident on any node in the cluster should be checked for the given name binding.
        Throws:
        UnknownActivityException - if no activity can be found with the specified primary key - may indicate that the activity has already ended and all its SLEE state removed.
        NameNotBoundException - if the name is not known to the activity context naming facility, or if the specified activity is not bound to it - may indicate that the name has already been unbound.
        InvalidPKeyException - if the activity primary key is invalid.

      • removeActivity

        void removeActivity​(String activityPKey)
             throws ManagementException,
                    InvalidPKeyException,
                    UnknownActivityException

        Remove an activity.

        Caution: This method irrevocably removes application state.

        This method forcibly ends an activity in the SLEE and should be used with caution. Stale activities or activities that might be considered candidates for forced removal can be found using getActivities(int, String, long, long, long, long, boolean).

        Note that Rhino’s own internal query liveness mechanism is sufficient for normal removal of stale activities. Removal of an activity using this method should only be required in the case of a resource adaptor or external resource error preventing Rhino’s query liveness from detecting that the activity is stale.

        Note that this method can only remove activities for which the invoked Rhino node (ie. the instance of this MBean as returned by RhinoHousekeepingMBean.getNodeHousekeeping(int)) is the processing node. An activity’s processing node can be queried using getActivityInfo(String, boolean).

        This method is equivalent to invoking removeActivity(String, boolean), passing the parameters removeActivity(activityPKey, false);.

        Parameters:
        activityPKey - string encoded activity primary key.
        Throws:
        UnknownActivityException - if no activity can be found with the specified primary key - may indicate that the activity has already ended and all its SLEE state removed.
        InvalidPKeyException - if the activity primary key is invalid.
        ManagementException - if a system failure occurs.

        This method forcibly ends an activity in the SLEE and should be used with caution. Stale activities or activities that might be considered candidates for forced removal can be found using getActivities(int, String, long, long, long, long, boolean).

        Note that Rhino’s own internal query liveness mechanism is sufficient for normal removal of stale activities. Removal of an activity using this method should only be required in the case of a resource adaptor or external resource error preventing Rhino’s query liveness from detecting that the activity is stale.

        Note that normally this method can only remove activities for which the invoked Rhino node (ie. the instance of this MBean as returned by RhinoHousekeepingMBean.getNodeHousekeeping(int)) is the processing node. An activity’s processing node can be queried using getActivityInfo(String, boolean, boolean). If the nonResident argument is true, this method will also check non-resident activities, such as those maintained externally by a key/value store, that are not currently owned by any active cluster node.

        Parameters:
        activityPKey - string encoded activity primary key.
        nonResident - boolean flag indicating if activities not currently resident on any active cluster node should be checked for presence of the specified activity.
        Throws:

        Replaced with getActiveTransactions(int, int) which is a more generalised version of this operation.

        Return summary information about long-running transactions in the SLEE. Long running transaction can occur when a profile MBean is left in the read-write state for a prolonged period of time, a client-demarcated user transaction is left active for a prolonged period of time, or a particular management operation takes a long time to complete.

        The results are returned as TabularData, where each entry is a CompositeData containing summary information about a transaction. Refer to Active Transaction Search Results in the interface descriptor for a descriptor of the CompositeData records returned by this method.

        Parameters:
        maxPerNode - maximum number of transactions to return from each node.
        minAge - minimum age, measured in seconds, of transactions to include in the return result. The minimum value for this argument is 30s.

        Force rollback of a long-running transaction. The transaction must still be active and must have been started at least 30s ago.

        When using the pool clustering mode, this method can only be used to affect transactions on this node. Specifying any other node ID will result in a ManagementException being thrown.

        Parameters:
        nodeID - The node ID of the cluster member on which the transaction was created.
        transactionID - the transaction ID of the transaction.
        Throws:
        javax.transaction.InvalidTransactionException - if the specified transaction does not exist, is not in the ACTIVE or MARKED FOR ROLLBACK state, or is less than 30s in age.
        ManagementException - if the specified node ID is not a current event router node, if the pool clustering mode is being used and nodeID is not equal to this node’s ID, or if a system failure occurs.

        Copy the current per-node desired state of services, resource adaptor entities, and the SLEE from this node to the specified target node. This will overwrite the current per-node settings of the target node, and will trigger convergence towards the new desired state if it differs from the current actual state. This will also delete any per-node state from the target which is not present on this node.

        If the pool clustering mode is being used, this method has no useful purpose and will always throw an UnsupportedOperationException.

        Parameters:
        targetNodeID - the node ID of the node to copy state to.
        Returns:
        true if per-node activation state changed for the target node, false if the target node already had the same per-node activation state.
        Throws:
        UnsupportedOperationException - if this method is invoked on an instance of a NodeHousekeepingMBean created for the cluster rather than a single node, or if this node is configured to use the pool clustering mode.
        InvalidArgumentException - if targetNodeID is an invalid node ID.

        Retrieve the current status of all event router threads.

        The returned table contains a breakdown of the current task of each event router thread at approximately the same point in time. Event router thread states are read concurrently without interrupting event processing so the result is not guaranteed to be an accurate point in time snapshot only an approximation.
