The property values specified must match the values specified when configuring WebSphere MQ product JMS resources.

In WebSphere MQ, names can have a maximum of 48 characters, with the exception of channels which have a maximum of 20 characters.

MA0C broker: When creating a WAS v6 topic connection factory for the MA0C broker, you should consider the following attribute values:

BrokerControlQueue

This value is fixed at SYSTEM.BROKER.CONTROL.QUEUE for the MA0C broker and is the queue the broker reads from.

BrokerVersion

Set this value to BASIC for the MA0C broker.

ClientID

Set this value to whatever you like for the MA0C broker (the value is string and is merely an identifier for the client application).

XA Enabled

Set this value to TRUE or FALSE for the MA0C broker (the setting you use is a performance enhancement flag - you will probably want to set this to 'true' most of the time).

BrokerMessage Selection

This value is fixed at CLIENT for the MA0C broker because the broker relies on client side message selection.

Direct Broker Authorization Type

This value is not required by the MA0C broker.

A topic connection factory for the WebSphere MQ product JMS provider has the following properties.

Name

The name by which this topic connection factory is known for administrative purposes within IBM WAS. The name must be unique within the JMS provider.

Data type

String

Description

A description of this topic connection factory for administrative purposes within IBM WAS.

Data type

String

JNDI Name

The JNDI name used to bind the topic connection factory into the appserver name space.

As a convention, use the fully qualified JNDI name; for example, in the form jms/Name, where Name is the logical name of the resource.

This name is used to link the platform binding information. The binding associates the resources defined by the deployment descriptor of the module to the actual (physical) resources bound into JNDI by the platform.

SSL cipher suite

Cipher suite to use for SSL connection to WebSphere MQ.

Set this property to a valid cipher suite provided by the JSSE provider. The value must match the CipherSpec specified on the SVRCONN channel as the Channel property.

Set this property, if we set the SSL Peer Name property.

SSL certificate store

List of zero or more Certificate Revocation List (CRL) servers used to check for SSL certificate revocation. If we specify a value for this property, use WebSphere MQ JVM at Java 2 version 1.4.

The value is a space-delimited list of entries of the form:

ldap: //hostname:[port]

A single slash (/) follows this value. If port is omitted, the default LDAP port of 389 is assumed. At connect-time, the SSL certificate presented by the server is checked against the specified CRL servers.

SSL peer name

For SSL, a distinguished name skeleton that must match the name provided by the WebSphere MQ queue manager. The distinguished name is used to check the identifying certificate presented by the server at connection time.

If this property is not set, such certificate checking is performed.

The SSL peer name property is ignored if SSL Cipher Suite property is not specified.

Is a list of attribute name and value pairs separated by commas or semicolons. For example:

CN=QMGR.*, OU=IBM, OU=WEBSPHERE

The example given checks the identifying certificate presented by the server at connect-time. For the connection to succeed, the certificate must have a Common Name beginning QMGR., and must have at least two Organizational Unit names, the first of which is IBM and the second WEBSPHERE. Checking is not case-sensitive.

Connection pool

Specifies an optional set of connection pool settings.

Connection pool properties are common to all J2C connectors.

The appserver pools connections and sessions with the JMS provider

to improve performance. This is independent from any WebSphere MQ connection pooling. You need to configure the connection and session pool properties appropriately for the applications, otherwise you may not get the connection and session behavior that you want.

Change the size of the connection pool if concurrent server-side access to the JMS resource exceeds the default value. The size of the connection pool is set on a per queue or topic basis.

Default	Selected
