## Overview

This class represents a JMS session pool, a server-managed pool of server sessions that enables an application to process messages concurrently.

Deprecated. 9.0.0.0 Replaced with message-dirven beans. This functionality will be removed in a future release.

## Related MBeans

This section describes attributes that provide access to other MBeans. For more information about the MBean hierarchy, refer to WebLogic Server MBean Data Model.

ConnectionConsumers JMSConnectionConsumers |

### ConnectionConsumers

The connection consumers for this JMS session pool. JMS connection consumers are queues (Point-To-Point) or topics (Pub/Sub) that retrieve server sessions and process messages. Once you have defined a session pool, you can configure one or more connection consumers for each session pool. This method is provided for backward compatibility.

Deprecated. 9.0.0.0 Replaced with message-driven beans.

Lookup Operation | `lookupJMSConnectionConsumer(String name)` Returns a `javax.management.ObjectName` for the instance of `JMSConnectionConsumerMBean` named `name`.
Privileges | Read/Write
Type | JMSConnectionConsumerMBean[]
Relationship type: | Reference.
Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server.

Factory Methods | `createJMSConnectionConsumer (java.lang.String name)` `destroyJMSConnectionConsumer (String connectionConsumer)` Factory methods do not return objects. See Using factory methods.
Lookup Operation | `lookupJMSConnectionConsumer(String name)` Returns a `javax.management.ObjectName` for the instance of `JMSConnectionConsumerMBean` named `name`.

## Attributes

This section describes the following attributes:

AcknowledgeMode ConnectionFactory ListenerClass Name Notes | Parent SessionsMaximum Transacted Type

### AcknowledgeMode

The acknowledge mode used by non-transacted sessions within this JMS session pool.

For transacted sessions, messages are acknowledged automatically when the session is committed and this value is ignored.

Privileges | Read/Write
Type | java.lang.String
Default Value | Auto

### ConnectionFactory

The JNDI name of the connection factory for this JMS session pool. Connection factories are used to create connections with predefined attributes.

Privileges | Read/Write
Type | java.lang.String

### ListenerClass

The name of the server-side listener class for this JMS session pool, which is used to receive and process messages concurrently.

Privileges | Read/Write
Type | java.lang.String

### Name

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

### Notes

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 `&lt;`. Carriage returns/line feeds are preserved.

Note:

  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

### Parent

Return the immediate parent for this MBean

Privileges | Read/Write
Type |

### SessionsMaximum

The maximum number of sessions allowed for this JMS session pool. A value of `-1` indicates that there is no maximum.

This attribute is dynamically configurable; however, it does not take effect until the session pool is restarted.

Privileges | Read/Write
Type | int
Default Value | -1
Minimum value | -1
Maximum value | 2147483647

### Transacted

Indicates whether this JMS session pool creates transacted sessions.

Privileges | Read/Write
Type | boolean

### Type

Returns the type of the MBean.

Privileges | Read only
Type | java.lang.String
Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server.

## Operations

This section describes the following operations:

freezeCurrentValue isSet restoreDefaultValue | unSet

### freezeCurrentValue

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.

Note:

  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. 9.0.0.0

Operation Name | `"freezeCurrentValue"`
Parameters | `Object [] { attributeName }` where: `attributeName` is an object of type `java.lang.String` that specifies: attributeName
Signature | `String [] { "java.lang.String" }`
Returns | `void`
Exceptions | `javax.management.AttributeNotFoundException` `javax.management.MBeanException`

### isSet

Returns true if the specified attribute has been set explicitly in this MBean instance.

Operation Name | `"isSet"`
Parameters | `Object [] { propertyName }` where: `propertyName` is an object of type `java.lang.String` that specifies: property to check
Signature | `String [] { "java.lang.String" }`
Returns | `boolean`

### restoreDefaultValue

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. 9.0.0.0

Operation Name | `"restoreDefaultValue"`
Parameters | `Object [] { attributeName }` where: `attributeName` is an object of type `java.lang.String` that specifies: attributeName
Signature | `String [] { "java.lang.String" }`
Returns | `void`
Exceptions | `javax.management.AttributeNotFoundException`

### unSet

Restore the given property to its default value.

Operation Name | `"unSet"`
Parameters | `Object [] { propertyName }` where: `propertyName` is an object of type `java.lang.String` that specifies: property to restore
Signature | `String [] { "java.lang.String" }`
Returns | `void`
