Default Provider topic connection factory settings
Use this panel to view or change the configuration properties of the selected JMS topic connection factory for use with the internal product Java Message Service (JMS) provider installed with WebSphere Application Server. These configuration properties control how connections are created between the JMS provider and the service integration bus that it uses.
To view this Application Client Resource Configuration Tool (ACRCT) page, click File > Open. After you browse for an EAR file, click Open. Expand the selected JAR file > Messaging Providers > Default Provider. Right-click Topic Connection Factories and click New. The following fields appear on the General tab.
Sets that have a default value display that appropriate value. Any settings that have fixed values have a drop down menu.
Name
The name of the topic connection factory.
Information Value Data type String
Description
A description of this topic connection factory for administrative purposes within IBM WAS.
Information Value Data type String
JNDI Name
The JNDI name used to match this topic connection factory definition to the deployment descriptor. This entry is a resource-ref name.
Information Value Data type String
User Name
The User Name used, with the Password property, for authentication if the calling application does not provide a userid and password explicitly. If this field is used, then the Properties field UserName is ignored.
If we specify a value for the User Name property, we must also specify a value for the Password property.
The connection factory User Name and Password properties are used if the calling application does not provide a userid and password explicitly. If a user name and password are specified, then an authentication alias is created for the factory where the password is encrypted.
Information Value Data type String
Password
The password used to create an encrypted. If we complete this field, then the Password field in the Properties box is ignored.
If we specify a value for the User Name property, we must also specify a value for the Password property.
Information Value Data type String
Re-Enter Password
Confirms the password.
Bus Name
The name of the bus to which the topic connection factory connects.
Information Value Data type String
Client Identifier
The name of the client. This field is required for topic subscriptions.
Information Value Data type String
Nonpersistent Messaging Reliability
The reliability applied to nonpersistent JMS messages sent using this connection factory.
If we want different reliability delivery options for individual JMS destinations, we can set this property to As bus destination. The reliability is then defined by the Reliability property of the bus destination to which the JMS destination is assigned.
Information Value Default ReliablePersistent Range
- None
- There is no message reliability for nonpersistent messages. If a nonpersistent message cannot be delivered, it is discarded.
- Best effort nonpersistent
- Messages are never written to disk, and are thrown away if memory cache overruns.
- Express nonpersistent
- Messages are written asynchronously to persistent storage if memory cache overruns, but are not kept over server restarts.
- Reliable nonpersistent
- Messages can be lost if a messaging engine fails, and can be lost under normal operating conditions.
- Reliable persistent
- Messages can be lost if a messaging engine fails, but are not lost under normal operating conditions.
- Assured persistent
- Highest degree of reliability where assured message delivery is supported.
- As Bus destination
- Use the delivery option configured for the bus destination.
Persistent Message Reliability
The reliability applied to persistent JMS messages sent using this connection factory.
If we want different reliability delivery options for individual JMS destinations, we can set this property to As bus destination. The reliability is then defined by the Reliability property of the bus destination to which the JMS destination is assigned.
Information Value Default ReliablePersistent Range
- None
- There is no message reliability for nonpersistent messages. If a nonpersistent message cannot be delivered, it is discarded.
- Best effort nonpersistent
- Messages are never written to disk, and are thrown away if memory cache overruns.
- Express nonpersistent
- Messages are written asynchronously to persistent storage if memory cache overruns, but are not kept over server restarts.
- Reliable nonpersistent
- Messages can be lost if a messaging engine fails, and can be lost under normal operating conditions.
- Reliable persistent
- Messages can be lost if a messaging engine fails, but are not lost under normal operating conditions.
- Assured persistent
- Highest degree of reliability where assured message delivery is supported.
- As Bus destination
- Use the delivery option configured for the bus destination.
Subscription Home
The name of the subscription home.
Information Value Data type String For shared non-durable subscription, the connection factory should be connected to the SubscriptionHome messaging engine during connection factory creation. To ensure that the connection factory is connected always to the SubscriptionHome messaging engine, set the Target field as the SubscriptionHome messaging engine name, Target type field as the Messaging engine name, and Target significance field as Required in the connection factory configuration.
When connection factory is not connected to the SubscriptionHome messaging engine due to improper connection factory settings, an attempt to create a shared non-durable subscription (createSharedConsumer API) results in the following exception:
WSIC8025E: Unable to create a shared nondurable subscription for destination <destination name> because the connection factory is not connected to the SubscriptionHome messagaing engine <subscription home messaging engine name>, but connected to the messaging engine <the messaging engine which the connection factory is connecting to>.
Share subscriptions
Controls whether subscriptions are shared across connections with members of a server cluster.
Normally, only one session at a time can have a TopicSubscriber for a particular subscription. Enable you to override this behavior, to enable a subscription to have multiple simultaneous consumers.
Information Value Data type Selection list Default In cluster Range
- In cluster
- Allows sharing of subscriptions when connections are made from within a server cluster.
- Always shared
- Subscriptions can be shared across connections.
- Never shared
- Subscriptions are never shared across connections.
Read Ahead
Controls the read-ahead optimization during message delivery.
Information Value Default Default Range Default, AlwaysOn and AlwaysOff
Target
The name of the Workload Manager target group containing the messaging engine.
Information Value Data type String
Target Type
The type of Workload Manager target group containing the messaging engine.
Information Value Default BusMember Range BusMember, Custom, ME
Target Significance
The priority of significance for the target specified.
Information Value Default Preferred Range Preferred, Required
Target Inbound Transport Chain
The name of the protocol that resolves to a group of messaging engines.
Information Value Data type String
Provider Endpoints
The list of comma separated endpoints used to connect to a bootstrap server.
Type a comma-separated list of endpoint triplets with the syntax: host:port:protocol.
Information Value Example BootstrapBasicMessaging corresponds to the remote protocol InboundBasicMessaging (JFAP-TCP/IP).
Default
- If the host name is not specified, then the default localhost is used as a default value.
- If the port number is not specified, then 7276 is used as a default value.
- If the chain name is not specified, a predefined chain, such as BootstrapBasicMessaging, is used as a default value.
Connection Proximity
The proximity that the messaging engine should have to the requester.
Information Value Default Bus Range Bus, Host, Cluster, Server
Temporary Topic Name Prefix
The prefix to apply to the names of temporary topics. This name is a maximum of 12 characters.
Information Value Data type String
