Type-Safe Access to BEA WebLogic Server 9.0 MBeans (Deprecated)

weblogic.management.runtime
Interface ThreadPoolRuntimeMBean

All Superinterfaces:

DynamicMBean, weblogic.health.HealthFeedback, MBeanRegistration, NotificationBroadcaster, weblogic.management.runtime.RuntimeMBean, WebLogicMBean

public interface ThreadPoolRuntimeMBean

extends weblogic.management.runtime.RuntimeMBean, weblogic.health.HealthFeedback

This bean is used to monitor the self-tuning queue

Deprecation of MBeanHome and Type-Safe Interfaces

This is a type-safe interface for a WebLogic Server MBean, which you can import into your client classes and access through weblogic.management.MBeanHome. As of 9.0, the MBeanHome interface and all type-safe interfaces for WebLogic Server MBeans are deprecated. Instead, client classes that interact with WebLogic Server MBeans should use standard JMX design patterns in which clients use the javax.management.MBeanServerConnection interface to discover MBeans, attributes, and attribute types at runtime. For more information, see "Developing Manageable Applications with JMX" on http://www.oracle.com/technology/documentation/index.html.

9.0.0.0

Method Detail

getCompletedRequestCount

public long getCompletedRequestCount()

The number of completed requests in the priority queue.

getExecuteThreadIdleCount

public int getExecuteThreadIdleCount()

The number of idle threads in the pool.

getExecuteThreads

public ExecuteThread[] getExecuteThreads()

An array of currently active threads in the pool.

See Also:

ExecuteThread

getExecuteThreadTotalCount

public int getExecuteThreadTotalCount()

The total number of threads in the pool.

getHealthState

public weblogic.health.HealthState getHealthState()

Specified by:

getHealthState in interface weblogic.health.HealthFeedback

getHoggingThreadCount

public int getHoggingThreadCount()

returns the threads that are being hogged by a request right now. These threads will either be declared as stuck after the configured timeout or will return to the pool before that. The self-tuning mechanism will backfill if necessary.

getMinThreadsConstraintsCompleted

public long getMinThreadsConstraintsCompleted()

Number of requests with min threads constraint picked up out of order for execution immediately since their min threads requirement was not met. This does not include the case where threads are idle during schedule.

getMinThreadsConstraintsPending

public int getMinThreadsConstraintsPending()

Number of requests that should be executed now to satisfy the min threads requirement

getPendingUserRequestCount

public int getPendingUserRequestCount()

The number of pending user requests in the priority queue. The priority queue contains requests from internal subsystems and users. This is just the count of all user requests.

getQueueLength

public int getQueueLength()

The number of pending requests in the priority queue. This is the total of internal system requests and user requests.

getSharedCapacityForWorkManagers

public int getSharedCapacityForWorkManagers()

Maximum amount of requests that can be accepted in the priority qeueue. Note that a request with higher priority will be accepted in place of a lower priority request already in the queue even after the threshold is reached. The lower priority request is kept waiting in the queue till all high priority requests are executed. Also note that further enqueues of the low priority requests are rejected right away.

getStandbyThreadCount

public int getStandbyThreadCount()

Returns the number of threads in the standby pool. Surplus threads that are not needed to handle the present work load are designated as standby and added to the standby pool. These threads are activated when more threads are needed.

getThroughput

public double getThroughput()

The mean number of requests completed per second

isSuspended

public boolean isSuspended()

Indicates if the RequestManager is suspended. A suspended manager will not dequeue work and dispatch threads till it is resumed.
