weblogic.management.configuration
Interface MinThreadsConstraintMBean

All Superinterfaces:
ConfigurationMBean, DeploymentMBean, DescriptorBean, DynamicMBean, MBeanRegistration, NotificationBroadcaster, SettableBean, WebLogicMBean

public interface MinThreadsConstraintMBean
extends DeploymentMBean

This MBean defines the minimum number of concurrent threads that should allocated to this constraint provided there are enough pending requests.

Multiple WorkManagers can share a common MinThreadsConstraint. MinThreadsConstraint perform their own bookkeeping and demand a thread when the constraint is not met and there are enough requests.

MinThreadsConstraint should be used to tell the WebLogic Server that a certain number of minimum threads are necessary to prevent server to server deadlocks. Although the server is self-tuning, specifying MinThreadsConstraint ensures that the server guarantees minimum threads to avoid the distributed deadlocks.

Method Detail

getCount

int getCount()
Minimum number of concurrent threads executing requests that share this constraint.

A count of 0 or -1 is treated as if the constraint is not present. This means that the constraint is ignored for these two values. A count > 0 can be dynamically changed to 0 to indicate that constraint enforcement is no longer needed.

Since:
9.0.0.0

setCount

void setCount(int count)
Min number of concurrent threads executing requests that share this constraint.

A count of 0 or -1 is treated as if the constraint is not present. This means that the constraint is ignored for these two values. A count > 0 can be dynamically changed to 0 to indicate that constraint enforcement is no longer needed.
