Interface Registry

  • public interface Registry
    The Coherence cluster management gateway is an abstraction of the basic JMX registration APIs that is specific to managing Coherence clustered resources. Though this interface is closely related to the JMX infrastructure, it is independent from javax.management.* classes. This enables remote management support for cluster nodes that are not co-located with any JMX services.

    MBean Names

    Each Coherence MBean has a unique ObjectName for registration in a MBeanServer that could either be co-located or remote in relation to the managed object. Each cluster node has a single instance of the following managed beans:
    Managed Bean ObjectName
    Managed Bean ObjectName
    ManagementMBean type=Management
    ReporterMBean type=Reporter
    ClusterMBean type=Cluster
    ClusterNodeMBean type=Node, nodeId=cluster node's id
    PointToPointMBean type=PointToPoint, nodeId=cluster node's id

    A cluster node may have zero or more instances of the following managed beans:

    Managed Bean ObjectName
    Managed Bean ObjectName
    ServiceMBean type=Service, name=service name,nodeId=cluster node's id
    CacheMBean type=Cache, service=service name,name=cache name, nodeId=cluster node's id[,tier=tier tag]
    StorageManagerMBean type=StorageManager, service=service name,cache=cache name, nodeId=cluster node's id
    ConnectionManagerMBean type=ConnectionManager, name=service name,nodeId=cluster node's id
    ConnectionMBean type=Connection, name=service name,nodeId=cluster node's id, UUID=connection's UUID 
    HealthCheckMBean type=Health, name=health check name,subType=health check subType,nodeId=cluster node's id
    The domain name for each managed bean will be assigned automatically (see getDomainName().)

A low utilization indicates that data is not being sent in large enough chunks to make efficient use of the network.
    ReceiverSuccessRate Float RO The receiver success rate for this cluster node since the node statistics were last reset. Receiver success rate is a ratio of the number of packets successfully acknowledged in a first attempt to the total number of received packets.

    ResendDelay Integer RW The minimum number of milliseconds that a packet will remain queued in the Publisher`s re-send queue before it is resent to the recipient(s) if the packet has not been acknowledged. Setting this value too low can overflow the network with unnecessary repetitions. Setting the value too high can increase the overall latency by delaying the re-sends of dropped packets. Additionally, change of this value may need to be accompanied by a change in SendAckDelay value.
    RoleName String RO A configured name that can be used to indicate the role of a Member to the application. While managed by Coherence, this property is used only by the application.
    SendAckDelay Integer RW The minimum number of milliseconds between the queueing of an Ack packet and the sending of the same. This value should be not more then a half of the ResendDelay value.
    SendQueueSize Integer RO The number of packets currently scheduled for delivery. This number includes both packets that are to be sent immediately and packets that have already been sent and awaiting for acknowledgment. Packets that do not receive an acknowledgment within ResendDelay interval will be automatically resent.

A queue entry is considered to be `ripe` for a write operation if it has been in the write-behind queue for no less than the QueueDelay interval. The `soft-ripe` time is the point in time prior to the actual `ripe` time after which an entry will be included in a batched asynchronous write operation to the CacheStore (along with all other `ripe` and `soft-ripe` entries). This attribute is only applicable if asynchronous writes are enabled (i.e. the value of the QueueDelay attribute is greater than zero) and the CacheStore implements the storeAll() method. The value of the element is expressed as a percentage of the QueueDelay interval. Valid values are doubles in the interval [0.0, 1.0].
    CacheHits Long RO The rough number of cache hits since the last time statistics were reset. A cache hit is a read operation invocation (i.e. get()) for which an entry exists in this map.

    Description String RO The cache description.
    ExpiryDelay Integer RW The time-to-live for cache entries in milliseconds. Value of zero indicates that the automatic expiry is disabled. Change of this attribute will not affect already-scheduled expiry of existing entries.
    HighUnits Integer RW The limit of the cache size measured in units. The cache will prune itself automatically once it reaches its maximum unit level. This is often referred to as the `high water mark` of the cache.
    HitProbability Double RO The rough probability (0 <= p <= 1) that the next invocation will be a hit, based on the statistics collected since the last time statistics were reset.
    LowUnits Integer RW The number of units to which the cache will shrink when it prunes. This is often referred to as a `low water mark` of the cache.

    PersistenceType String RO Deprecated - use attribute CacheStoreType instead.
    QueueDelay Integer RW The number of seconds that an entry added to a write-behind queue will sit in the queue before being stored via a CacheStore. Applicable only for WRITE-BEHIND persistence type.
    QueueSize Integer RO The size of the write-behind queue (if persistence type is WRITE-BEHIND) or the number of pending writes for non-blocking stores (stores implementing the NonBlockingEntryStore interface).
    RefreshFactor Double RW The RefreshFactor attribute is used to calculate the `soft-expiration` time for cache entries. Soft-expiration is the point in time prior to the actual expiration after which any access request for an entry will schedule an asynchronous load request for the entry. This attribute is only applicable for a ReadWriteBackingMap which has an internal LocalCache with scheduled automatic expiration. The value of this element is expressed as a percentage of the internal LocalCache expiration interval. Valid values are doubles in the interval[0.0, 1.0]. If zero, refresh-ahead scheduling will be disabled.
    RefreshTime Date RO The timestamp when this model was last retrieved from a corresponding node. For local servers it is the local time.
    RequeueThreshold Integer RW The maximum size of the write-behind queue for which failed CacheStore write operations are requeued. If zero, the write-behind requeueing will be disabled. Applicable only for WRITE-BEHIND persistence type.
    Size Integer RO The number of entries in the cache.
    StoreAverageBatchSize Long RO The average number of entries stored per CacheStore write operation. A call to the store() method is counted as a batch of one, whereas a call to the storeAll() method is counted as a batch of the passed Map size. The value of this attribute is -1 if the persistence type is NONE.
    StoreAverageReadMillis Long RO The average time (in millis) spent per read operation; -1 if persistence type is NONE. This statistic is only tracked for caches associated with a CacheStore.
    StoreAverageWriteMillis Long RO The average time (in millis) spent per write operation; -1 if persistence type is NONE. This statistic is only tracked for caches associated with a CacheStore.
    StoreFailures Long RO The total number of CacheStore failures (load, store and erase operations); -1 if persistence type is NONE.

    StoreWrites Long RO The total number of store and erase operations; -1 if persistence type is NONE or READ-ONLY.
    TotalGets Long RO The total number of get() operations since the last time statistics were reset.
    TotalGetsMillis Long RO The total number of milliseconds spent on get() operations since the last time statistics were reset. This statistic is only tracked for caches that may incur expensive hits (for example the front of a near cache).
    TotalPuts Long RO The total number of put() operations since the last time statistics were reset.
    TotalPutsMillis Long RO The total number of milliseconds spent on put() operations since the last time statistics were reset. This statistic is only tracked for caches that may incur expensive hits (for example the front of a near cache).
    UnitFactor Integer RO The factor by which the Units, LowUnits and HighUnits properties are adjusted. Using a BINARY unit calculator, for example, the factor of 1048576 could be used to count megabytes instead of bytes.
    Units Integer RO The size of the cache measured in units. This value needs to be adjusted by the UnitFactor.
    UnitsBytes Long RO The size of the cache measured in bytes.

    • Method Detail

      • getDomainName

        String getDomainName()
        Domain name for managed beans registered by Coherence clustered services. For cluster nodes that are co-located with an MBeanServer instance, the returned value is "Coherence" (or "Coherence@NNN" in a case of a name conflict when multiple clusters run within the same JVM). For the nodes that are managed remotely and do not run an MBeanServer, the returned value is an empty string.
        Returns:
        the domain name

      • ensureGlobalName

        String ensureGlobalName​(String sName)
        Convert the passed MBean name to a global name if necessary.

        A name is global if it satisfies either of the two conditions:

        1. it contains a nodeId key property that differentiates an MBean name from an otherwise identical MBean name registered by a different cluster node;
        2. it contains a responsibility key property and is guaranteed to be registered by no more than one cluster node.
        Parameters:
        sName - any valid MBean name
        Returns:
        a fully qualified version of the given MBean name

      • ensureGlobalName

        String ensureGlobalName​(String sName,
                        Member member)
        Convert the passed MBean name to a global name for a given cluster Member if necessary.

        A name is global if it satisfies either of the two conditions:

        1. it contains a nodeId key property that differentiates an MBean name from an otherwise identical MBean name registered by a different cluster node;
        2. it contains a responsibility key property and is guaranteed to be registered by no more than one cluster node.
        Parameters:
        sName - any valid MBean name
        member - a cluster member
        Returns:
        a fully qualified version of the given MBean name

      • isRegistered

        boolean isRegistered​(String sName)
        Check whether or not the specified name is already registered.
        Parameters:
        sName - the MBean's name
        Returns:
        true iff the specified name is already registered

      • register

        void register​(String sName,
              Object oBean)
        Register a manageable object. The object itself is not necessarily an MBean. If the object is not an MBean (standard or dynamic), the Registry will determine what MBean corresponds to the object and will instantiate and register the necessary MBean either locally or globally depending on the type of the managed object.

        If the given MBean name is a global name, the corresponding MBean will be registered with all available MBeanServers (local or remote); otherwise, the MBean will only be registered with the local MBeanServer.

        Parameters:
        sName - the MBean's name
        oBean - the managed object

      • unregister

        void unregister​(String sName)
        Unregister managed objects that match the specified object name or name pattern (query name).
        Parameters:
        sName - MBean's name or a name pattern

      • getNotificationManager

        NotificationManager getNotificationManager()
        Obtain a reference to the NotificationManager for this Registry.
        Returns:
        the NotificationManager object

      • getMBeanServerProxy

        MBeanServerProxy getMBeanServerProxy()
        Obtain a reference to the MBeanServerProxy for this Registry.
        Returns:
        the MBeanServerProxy

      • isExtendedMBeanName

        boolean isExtendedMBeanName()
        Return true iff extended global MBean names are to be used.
        Returns:
        true iff extended global MBean names are to be used
