A Oracle Coherence MBeans Reference

This appendix provides a reference of the MBeans for managing and monitoring different parts of Oracle Coherence. The reference provides a detailed description of the attributes and operations of the MBeans.

The Registration interface also includes descriptions of the MBeans. See the Registration interface in the Java API Reference for Oracle Coherence. An MBean-capable agent (such as JConsole) also shows MBean information. See Chapter 2, "Using JMX to Manage Oracle Coherence," for more information about accessing Oracle Coherence MBeans.

Table A-1 lists the MBeans for managing and monitoring Oracle Coherence.

CacheMBean

The CacheMBean MBean represents a cache. A cluster member includes zero or more instances of this managed bean depending on the number of caches that are configured for each data service type (distributed, replicated, and so on). This MBean provides operational and performance statistics for a cache. Some MBean attributes are writable and allow the behavior of a cache to be changed in real time.

The object name of the MBean is:

type=Cache,service=service name,name=cache name,nodeId=cluster node id,tier=tier tag

Note:

The CacheMBean MBean contains many attributes that are not applicable to transactional caches. A transactional cache returns a -1 value if attributes are invoked that do not apply. See Developing Applications with Oracle Coherence for a list of the supported attributes and transaction-specific descriptions.

Attributes

Table A-2 describes the attributes for CacheMBean.

Table A-2 CacheMBean Attributes

Attribute	Type	Access	Description
`AverageGetMillis`	`Double`	read-only	The average number of milliseconds per `get()` invocation since the statistics were last reset
`AverageHitMillis`	`Double`	read-only	The average number of milliseconds per `get()` invocation that is a hit since the statistics were last reset
`AverageMissMillis`	`Double`	read-only	The average number of milliseconds per `get()` invocation that is a miss since the statistics were last reset
`AveragePutMillis`	`Double`	read-only	The average number of milliseconds per `put()` invocation since the statistics were last reset
`BatchFactor`	`Double`	read/write	The `BatchFactor` attribute is used to calculate the soft-ripe time for write-behind queue entries. 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 before the actual ripe time after which an entry is included in a batch asynchronous write operation to the cache store (along with all other ripe and soft-ripe entries). This attribute is only applicable if asynchronous writes are enabled (that is, the value of the `QueueDelay` attribute is greater than zero) and the cache store 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`	read-only	The rough number of cache visits since the statistics were last reset. A cache hit is a read operation invocation (that is, `get()`) for which an entry exists in this map.
`CacheHitsMillis`	`Long`	read-only	The total number of milliseconds (since the statistics were last reset) for the `get()` operations for which an entry existed in this map
`CacheMisses`	`Long`	read-only	The rough number of cache misses since the statistics were last reset
`CacheMissesMillis`	`Long`	read-only	The total number of milliseconds (since the statistics were last reset) for the `get()` operations for which no entry existed in this map
`CachePrunes`	`Long`	read-only	The number of prune operations since the statistics were last reset. A prune operation occurs every time the cache reaches its high-water mark as specified by the `HighUnits` attribute.
`CachePrunesMillis`	`Long`	read-only	The total number of milliseconds for the prune operations since the statistics were last reset
`Description`	`String`	read-only	The cache description
`ExpiryDelay`	`Integer`	read/write	The time-to-live for cache entries in milliseconds. A value of zero indicates that the automatic expiry is disabled. Changing this attribute does not affect existing entries that are scheduled to expire.
`HighUnits`	`Integer`	read/write	The limit of the cache size measured in units. The cache prunes itself automatically after it reaches its maximum unit level. This is often referred to as the high-water mark of the cache.
`HitProbability`	`Double`	read-only	The rough probability (`0 <= p <= 1`) that the next invocation is a hit since the last time statistics were reset
`LowUnits`	`Integer`	read/write	The number of units to which the cache shrinks when it prunes. This is often referred to as a low-water mark of the cache
`PersistenceType`	`String`	read-only	The persistence type for this cache. Possible values include: `NONE`, `READ-ONLY`, `WRITE-THROUGH`, `WRITE-BEHIND`.
`QueueDelay`	`Integer`	read/write	The number of seconds that an entry added to a write-behind queue sits in the queue before being stored using a cache store. This attribute is only applicable if the persistence type is `WRITE-BEHIND`.
`QueueSize`	`Integer`	read-only	The size of the write-behind queue. This attribute is only applicable if the persistence type is `WRITE-BEHIND`.
`RefreshFactor`	`Double`	read/write	This attribute is used to calculate the soft-expiration time for cache entries. Soft-expiration is the point in time before the actual expiration after which any access request for an entry schedules an asynchronous load request for the entry. This attribute is only applicable for a read/write backing map that has an internal local cache with scheduled automatic expiration. The value of this element is expressed as a percentage of the internal local cache expiration interval. Valid values are doubles in the interval [0.0, 1.0]. If the factor is zero, refresh-ahead scheduling is disabled.
`RefreshTime`	`Date`	read-only	The timestamp when this model was last retrieved from a corresponding member. For local servers, it is the local time.
`RequeueThreshold`	`Integer`	read/write	The size of the write-behind queue at which additional actions could be taken. If the size is zero, write-behind requeuing is disabled. Otherwise, this value controls the frequency of the corresponding log messages. For example, a value of 100 produces a log message every time the size of the write queue is a multiple of 100.
`Size`	`Integer`	read-only	The number of entries in the cache
`StoreAverageBatchSize`	`Long`	read-only	The average number of entries stored for each cache store write operation since the statistics were last reset. 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 is `-1` if the persistence type is `NONE`.
`StoreAverageReadMillis`	`Long`	read-only	The average time (in milliseconds) spent per read operation since the statistics were last reset. The value is `-1` if the persistence type is `NONE`.

`StoreFailures`	`Long`	read-only	The total number of cache store failures (load, store, and erase operations) since the statistics were last reset. The value is `-1` if the persistence type is `NONE.`
`StoreReadMillis`	`Long`	read-only	The cumulative time (in milliseconds) spent on load operations since the statistics were last reset. The value is `-1` if the persistence type is `NONE`.
`StoreReads`	`Long`	read-only	The total number of load operations since the statistics were last reset. The value is `-1` if the persistence type is `NONE`.
`StoreWriteMillis`	`Long`	read-only	The cumulative time (in milliseconds) spent on store and erase operations since the statistics were last reset. The value is `-1` if the persistence type is `NONE` or `READ-ONLY`.
`StoreWrites`	`Long`	read-only	The total number of store and erase operations since the statistics were last reset. The value is `-1` if the persistence type is `NONE` or `READ-ONLY`.
`TotalGets`	`Long`	read-only	The total number of `get()` operations since the statistics were last reset
`TotalGetsMillis`	`Long`	read-only	The total number of milliseconds spent on `get()` operations since the statistics were last reset
`TotalPuts`	`Long`	read-only	The total number of `put()` operations since the statistics were last reset
`TotalPutsMillis`	`Long`	read-only	The total number of milliseconds spent on `put()` operations since the statistics were last reset
`UnitFactor`	`Integer`	read-only	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`	read-only	The size of the cache measured in units. This value must be adjusted by the `UnitFactor`.

A low utilization indicates that data is not being sent in large enough chunks to make efficient use of the network.
`PublisherSuccessRate`	`Float`	read-only	The publisher success rate for this cluster member since the member statistics were last reset. The publisher success rate is a ratio of the number of packets successfully delivered in a first attempt to the total number of sent packets.

The receiver success rate is a ratio of the number of packets that were successfully acknowledged in a first attempt to the total number of received packets. A failure count increments when a redelivery of a previously received packet is detected. Very high inbound network latency or lost ACK packets can cause a low success rate.
`RefreshTime`	`Date`	read-only	The timestamp when this model was last retrieved from a corresponding member. For local servers, it is the local time.
`ResendDelay`	`Integer`	read/write	The minimum number of milliseconds that a packet remains queued in the publisher`s resend queue before it is re-sent to any recipients 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-sending of dropped packets. Change of this value may require a change in the `SendAckDelay` value.
`RoleName`	`String`	read-only	A name that indicates the role of a cluster member to the application. Use a name that is meaningful to the application.
`SendAckDelay`	`Integer`	read/write	The minimum number of milliseconds between the queuing and sending of an ACK packet. This value should not be more then half of the `ResendDelay` value.
`SendQueueSize`	`Integer`	read-only	The number of packets that are currently scheduled for delivery. This number includes both packets that are to be sent immediately and packets that have been sent and are awaiting for an acknowledgment. Packets that do not receive an acknowledgment within the `ResendDelay` interval are automatically re-sent.
`SiteName`	`String`	read-only	A name for the site where the member is located. The name should be the same for members that are on the same physical site (for example, data center), and different for members that are on different physical sites

A recoverable disconnect is an abnormal event that is registered when the TcpRing peer drops the TCP connection, but recovers after no more than the maximum configured number of attempts. A value of `-1` indicates that TcpRing is disabled.
`Timestamp`	`Date`	read-only	The date/time value (in cluster time) that this member joined the cluster
`TrafficJamCount`	`Integer`	read/write	The maximum total number of packets in the send and resend queues that forces the publisher to pause client threads. A value of zero means no limit.
`TrafficJamDelay`	`Integer`	read/write	The number of milliseconds to pause client threads when a traffic jam condition has been reached. Anything less than one (for example, zero) is treated as one millisecond.
`UnicastAddress`	`String`	read-only	The datagram socket IP address that is used by this member for point-to-point communication
`UnicastPort`	`Integer`	read-only	The datagram socket port that is used by this member for point-to-point communication

The terms task and request have unique definitions within Oracle Coherence. Understand the terms before setting the task-related and request-related attributes for ServiceMBean.

Task – A task is an invoked object that executes on one or more members. The objects include filters, invocation agents (entry processors and aggregators), or single-pass agents (Invocable objects).
Request – A request is the round-trip required to complete a task. A request begins the moment a task is sent for execution by a client and includes the following:
- The time it takes to deliver the request to an executing member (server)
- The interval between the time the task is received and placed into a service queue until the execution starts
- The task execution time
- The time it takes to deliver a result back to the client

TransactionManagerMBean

The TransactionManagerMBean MBean represents a transaction manager and is specific to the transactional framework. A cluster member includes zero or more instances of this managed bean depending on the number of configured transactional caches. The MBean provides global transaction manager statics by aggregating service-level statistics from all transaction service instances. Each cluster member has one instance of the transaction manager MBean for each service.

The object name of the MBean is:

Note:

For certain transaction manager attributes, the coordinator member for the transaction maintains the count even though multiple members participate in the transaction. For example, a transaction may include modifications to entries stored on multiple members, but the TotalCommitted attribute only increments on the MBean on the member that coordinated the commit of that transaction.
