Interface MaxThreadsConstraintMBean

All Superinterfaces:

public interface MaxThreadsConstraintMBean

extends DeploymentMBean

This MBean defines the max number of concurrent threads that can execute requests sharing this max constraint.

MaxThreadsConstraint can be used to tell the server that the requests are constrained by an external resource like a database and allocating more threads that the external resource limit is not going to help since the extra threads are just going to wait.

Since:

9.0.0.0

getCount

int getCount()

Maximum number of concurrent threads that can execute requests sharing this constraint.

A count of 0 or -1 is treated as if the constraint is not present. This means that no constraint is enforced 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)

Max number of concurrent threads that can execute requests sharing this constraint.

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

getConnectionPoolName

String getConnectionPoolName()

Name of the connection pool whose size is taken as the max constraint.

This can be the name of a JDBC data source. The max capacity of the data source is used as the constraint.

setConnectionPoolName

void setConnectionPoolName(String connectionPoolName)

Name of the connection pool whose size is taken as the max constraint.

This can be the name of a JDBC data source. The max capacity of the data source is used as the constraint.

setQueueSize

void setQueueSize(int queueSize)

Desired size of the MaxThreadsConstraint queue for requests pending execution.

Set the approximate size of the MaxThreadsConstraint requests queue. Requests are added to this queue if they are not yet eligible for execution due the the maximum number of concurrent threads that can execute requests sharing this constraint has been reached. The actual size of the queue created may be different from the value set here. For example, it may be rounded up to the nearest power of 2. Setting a large queue size would increase memory consumption. It is best to not set the queue size to be larger than necessary.

Since:

12.1.2.0

getQueueSize

int getQueueSize()

Desired size of the MaxThreadsConstraint queue for requests pending execution.

Since:

12.1.2.0
