This bean is used to configure an execute queue and its associated thread pool.
Fully Qualified Interface Name | If you use the getMBeanInfo operation in MBeanTypeServiceMBean, supply the following value as this MBean's fully qualified interface name:weblogic.management.configuration.ExecuteQueueMBean

Factory Methods |
This section describes the following attributes:
The user-specified name of this MBean instance.
This name is included as one of the key properties in the
MBean's javax.management.ObjectName
:
Name=user-specified-name
Privileges | Read/Write |
Type | java.lang.String |
Optional information that you can include to describe this configuration.
WebLogic Sever saves this note in the domain's configuration
file (config.xml
) as XML PCDATA. All left angle
brackets (<) are converted to the XML entity
<
. Carriage returns/line feeds are
preserved.
If you create or edit a note from the Administration Console, the Administration Console does not preserve carriage returns/line feeds.
Privileges | Read/Write |
Type | java.lang.String |
Return the immediate parent for this MBean
Privileges | Read/Write |
Type |
The maximum number of simultaneous requests that this server can hold in the queue.
Privileges | Read/Write |
Type | int |
Default Value | 65536 |
Minimum value | 256 |
Maximum value | 1073741824 |
The percentage of the Queue Length size that can be reached before this server indicates an overflow condition for the queue. If the overflow condition is reached and the current thread count has not reached the ThreadsMaximum value, then ThreadsIncrease number of threads are added.
Privileges | Read/Write |
Type | int |
Default Value | 90 |
Minimum value | 1 |
Maximum value | 99 |
The number of threads assigned to this queue.
Privileges | Read/Write |
Type | int |
Default Value | 15 |
Minimum value | 0 |
Maximum value | 65536 |
Specifies the number of threads to increase the queue length when the queue length theshold is reached. This threshold is determined by the QueueLengthThresholdPercent value.
The following consideration applies to the dynamic nature of ThreadsMaximum and ThreadsIncrease attributes. If any of these attributes change during runtime, the changed value comes into effect when the next request is submitted to the execute queue and the scheduler decides to increase threads depending on the queue threshold conditions.
Privileges | Read/Write |
Type | int |
Default Value | 0 |
Minimum value | 0 |
Maximum value | 65536 |
The maximum number of threads that this queue is allowed to have; this value prevents WebLogic Server from creating an overly high thread count in the queue in response to continual overflow conditions.
A note about dynamic nature of ThreadsMaximum and ThreadsIncrease attributes. If any of these attributes change during runtime, the changed value comes into effect when the next request is submitted to the execute queue and the scheduler decides to increase threads depending on the queue threshold conditions. Imagine a scenario where the queue capacity has already reached the max threshold and the current thread count is already equal to ThreadsMaximum value. If more work is coming into the queue and the administrator wishes to increase the ThreadsMaximum a little to add a few more threads, he/she can do so by changing these attributes dynamically. Please note that the changed value is evaluated when the next request is submitted.
Privileges | Read/Write |
Type | int |
Default Value | 400 |
Minimum value | 1 |
Maximum value | 65536 |
The minimum number of threads that WebLogic Server will maintain in the queue.
Privileges | Read/Write |
Type | int |
Default Value | 5 |
Minimum value | 0 |
Maximum value | 65536 |
Returns the type of the MBean.

Type | java.lang.String |
Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server. |
This section describes the following operations:
If the specified attribute has not been set explicitly, and if the attribute has a default value, this operation forces the MBean to persist the default value.
Unless you use this operation, the default value is not saved and is subject to change if you update to a newer release of WebLogic Server. Invoking this operation isolates this MBean from the effects of such changes.
To insure that you are freezing the default value, invoke the
restoreDefaultValue
operation before you invoke
this.
This operation has no effect if you invoke it on an attribute that does not provide a default value or on an attribute for which some other value has been set.
Deprecated.
Operation Name | "freezeCurrentValue" |
Parameters | Object [] { attributeName }
where:
|
Signature | String [] {
"java.lang.String" } |
Returns |
void
|
Exceptions |
|
Returns true if the specified attribute has been set explicitly in this MBean instance.
Operation Name | "isSet" |
Parameters | Object [] { propertyName }
where:
|
Signature | String [] {
"java.lang.String" } |
Returns |
boolean
|
If the specified attribute has a default value, this operation removes any value that has been set explicitly and causes the attribute to use the default value.
Default values are subject to change if you update to a newer
release of WebLogic Server. To prevent the value from changing if
you update to a newer release, invoke the
freezeCurrentValue
operation.
This operation has no effect if you invoke it on an attribute that does not provide a default value or on an attribute that is already using the default.
Deprecated.
Operation Name | "restoreDefaultValue" |
Parameters | Object [] { attributeName }
where:
|
Signature | String [] {
"java.lang.String" } |
Returns |
void
|
Exceptions |
|
Restore the given property to its default value.
Operation Name | "unSet" |
Parameters | Object [] { propertyName }
where:
|
Signature | String [] {
"java.lang.String" } |
Returns |
void
|
