Overview
Requests to a server instance are placed in an execute queue. Each request is assigned to a thread within the queue that performs the work.
By default, a new server instance is configured with a default execute queue, weblogic.kernel.default, that contains 15 threads. In addition, WebLogic Server provides two other pre-configured queues:
weblogic.admin.HTTP—Available only on Administration Servers, this queue is reserved for communicating with the Administration Console; you cannot reconfigure it.
weblogic.admin.RMI—Both Administration Servers and Managed Servers have this queue; it is reserved for administrative traffic; you cannot reconfigure it.
Unless you configure additional execute queues, and assign applications to them, web applications and RMI objects use weblogic.kernel.default.
Use this page to configure a new, user-defined execute queue for use with applications on this server, or to edit an existing execute queue.

Queue Length
|
The maximum number of simultaneous requests that the server instance can hold in the queue.
|
Minimum: 256
Maximum: 1073741824
Default: 65536
|
|
Queue Length Threshold Percent
|
The percentage (from 1-99) of the Queue Length size that can be reached before the server indicates an overflow condition for the queue. All actual queue length sizes below the threshold percentage are considered normal; sizes above the threshold percentage indicate an overflow. When an overflow condition is reached, WebLogic Server logs an error message and increases the number of threads in the queue by the value of the Threads Increase attribute to help reduce the workload.

Minimum: 1
Maximum: 99
Default: 90

Thread Count

Default: 15
|
|
Threads Increase
|
The number of threads to be added to the queue when an overflow condition occurs. If you specify zero threads (the default), the server instance changes its health state to "warning" in response to an overflow condition in the thread, but it does not increase the thread count.
|
Minimum: 0
Maximum: 65536
Default: 0
|
|
Threads Maximum
|
The maximum number of threads that this queue can have; this value prevents WebLogic Server from creating an overly high thread count in the queue in response to continual overflow conditions.
