This section lists and defines each of the standard connector configuration properties.
The queue that is used by the integration broker to send administrative messages to the connector.
The default value is CONNECTORNAME/ADMININQUEUE.
The queue that is used by the connector to send administrative messages to the integration broker.
The default value is CONNECTORNAME/ADMINOUTQUEUE.
Level of trace messages for the application-specific component. The default is 0. The connector delivers all trace messages applicable at the tracing level set or lower.
Name that uniquely identifies the connector's application. This name is used by the system administrator to monitor the WebSphere business integration system environment. This property must have a value before you can run the connector.
Identifies the integration broker type that you are using. Set to WMQIB for WebSphere MQ Integrator Broker.
Specifies the character code set used to map from a character (such as a letter of the alphabet, a numeric representation, or a punctuation mark) to a numeric value.
The default value is ascii.
This property allows a JMS-enabled connector with a JMS event store to provide guaranteed event delivery, in which an event is removed from the source queue and placed on the destination queue as a single JMS transaction.
The default value is JMS. It can also be set to no value.
When ContainerManagedEvents is set to JMS, you must configure the following properties to enable guaranteed event delivery:
You must also configure a data handler with the MimeType, DHClass, and DataHandlerConfigMOName (optional) properties. To set those values, use the Data Handler tab in Connector Configurator. The fields for the values under the Data Handler tab will be displayed only if you have set ContainerManagedEvents to JMS.
This property only appears if the DeliveryTransport property is set to the value JMS.
The queue that is used by the connector to send business objects to the integration broker.
The default value is DELIVERYQUEUE.
Specifies the transport mechanism for the delivery of events. Possible values are MQ for WebSphere MQ, IDL for CORBA IIOP, or JMS for Java Messaging Service.
If WMQIB is the broker type, the value may only be JMS.
The connector sends service call requests and administrative messages over CORBA IIOP if the value configured for the DeliveryTransport property is MQ or IDL.
Use WebSphere MQ rather than IDL for event delivery transport, unless you must have only one product. WebSphere MQ offers the following advantages over IDL:
Enables communication between the connector and client connector framework using Java Messaging Service (JMS).
If you select JMS as the delivery transport, additional JMS properties such as "jms.MessageBrokerName," "jms.FactoryClassName," "jms.Password," and "jms.UserName," display in Connector Configurator. The first two of these properties are required for this transport.
In this environment, you may experience difficulty starting the both the connector controller (on the server side) and the connector (on the client side) due to memory use within the WebSphere MQ client. If your installation uses less than 768M of process heap size, IBM recommends that you set:
This script resides in the \bin directory below the product directory. With a text editor, add the following line as the first line in the CWSharedEnv.sh script:
export LDR_CNTRL=MAXDATA=0x30000000
This line restricts heap memory usage to a maximum of 768 MB (3 segments * 256 MB). If the process memory grows more than this limit, page swapping can occur, which can adversely affect the performance of your system.
Setting this property to true enables a JMS-enabled connector to ensure that duplicate events are not delivered to the delivery queue. To use this feature, the connector must have a unique event identifier set as the business object's ObjectEventId attribute in the application specific code. This is done during connector development.
This property can also be set to false.
If the connector experiences an error while processing a message then the connector moves the message to the queue specified in this property, along with a status indicator and a description of the problem.
The default value is CONNECTORNAME/FAULTQUEUE.
The maximum heap size for the agent (in megabytes). This property is applicable only if the RepositoryDirectory value is <REMOTE>.
The default value is 128m.
The maximum native stack size for the agent (in kilobytes). This property is applicable only if the RepositoryDirectory value is <REMOTE>.
The default value is 128k.
The minimum heap size for the agent (in megabytes). This property is applicable only if the RepositoryDirectory value is <REMOTE>.
The default value is 1m.
Specifies the class name to instantiate for a JMS provider. You must set this connector property when you choose JMS as your delivery transport mechanism (DeliveryTransport).
The default is CxCommon.Messaging.jms.IBMMQSeriesFactory.
Specifies the broker name to use for the JMS provider. You must set this connector property when you choose JMS as your delivery transport mechanism (DeliveryTransport).
The default is crossworlds.queue.manager.
Specifies the maximum number of concurrent service call requests that can be sent to a connector at the same time. Once that maximum is reached, new service calls block and wait for another request to complete before proceeding.
The default value is 10.
Specifies the password for the JMS provider. A value for this property is optional.
There is no default.
Specifies the user name for the JMS provider. A value for this property is optional.
There is no default.
Specifies the language code, country or territory, and, optionally, the associated character code set. The value of this property determines such cultural conventions as collation and sort order of data, date and time formats, and the symbols used in monetary specifications.
A locale name has the following format:
ll_TT.codeset
where:
By default only a subset of supported locales display in the drop list. To add other supported values to the drop list, you must manually modify the \Data\Std\stdConnProps.xml file in the product directory. For more information, see the appendix on Connector Configurator.
The default value is en_US. If the connector has not been internationalized, the only valid value for this property is en_US. To determine whether a specific connector has been internationalized, see the connector version list (NEED WEB SITE).
Specifies whether to log errors to the integration broker's log destination. Logging to the broker's log destination also turns on e-mail notification, which generates e-mail messages for the MESSAGE_RECIPIENT specified in the InterchangeSystem.cfg file when errors or fatal errors occur.
As an example, when a connector loses its connection to its application, if LogAtInterChangeEnd is set to true, an e-mail message is sent to the specified message recipient. The default is false.
The maximum number of events in the controller buffer. This property is used by flow control and is applicable only if the value of the RepositoryDirectory property is <REMOTE>.
The value can be a positive integer between 1 and 2147483647. The default value is 2147483647.
The name of the connector message file. The standard location for the message file is \connectors\messages. Specify the message filename in an absolute path if the message file is not located in the standard location.
If a connector message file does not exist, the connector uses InterchangeSystem.txt as the message file. This file is located in the product directory.
The logical queue that the connector uses to monitor duplicate events. It is used only if the DeliveryTransport property value is JMS and DuplicateEventElimination is set to TRUE.
The default value is CONNECTORNAME/MONITORQUEUE
Time to stop polling the event queue. The format is HH:MM, where HH represents 0-23 hours, and MM represents 0-59 seconds.
You must provide a valid value for this property. The default value is HH:MM, but must be changed.
The amount of time between polling actions. Set PollFrequency to one of the following values:
The default is 10000.
Designates the number of items from the application that the connector should poll for. If the adapter has a connector-specific property for setting the poll quantity, the value set in the connector-specific property will override the standard property value.
The time to start polling the event queue. The format is HH:MM, where HH represents 0-23 hours, and MM represents 0-59 seconds.
You must provide a valid value for this property. The default value is HH:MM, but must be changed.
The queue that is used by the integration broker to send business objects to the connector.
The default value is REQUESTQUEUE.
The location of the repository from which the connector reads the XML schema documents that store the meta-data for business object definitions.
When the integration broker is WMQIB, this value must be set to <local directory>.
Designates the JMS response queue, which delivers a response message from the connector framework to the integration broker.
Causes the connector to shut down and restart automatically after it has processed a set number of events. You set the number of events in RestartCount. The connector must be in polling mode (set PollFrequency to "p") for this property to take effect.
Once the set number of events has passed through request processing, the connector is shut down and restarted the next time it polls.
Specifies the number of times the connector attempts to restart itself. When used for a parallel connector, specifies the number of times the master connector application-specific component attempts to restart the slave connector application-specific component.
The default is 3.
Specifies the interval in minutes at which the connector attempts to restart itself. When used for a parallel connector, specifies the interval at which the master connector application-specific component attempts to restart the slave connector application-specific component.
The default is 1.
This property allows you to configure the value of the field domain name in the JMS header. When data is sent to WebSphere MQ Integrator Broker over JMS transport, the connector framework writes JMS header information, with a domain name and a fixed value of mrm. A configurable domain name enables users to track how WebSphere MQ Integrator Broker processes the message data.
A sample header would look like this:
<mcd><Msd>mrm</Msd><Set>3</Set><Type> Retek_POPhyDesc</Type><Fmt>CwXML</Fmt></mcd>
The default value is mrm, but it may also be set to xml. This property only appears when DeliveryTransport is set to JMS and WireFormat is set to CwXML.
Designates the JMS source queue for the connector framework in support of guaranteed event delivery for JMS-enabled connectors that use a JMS event store. For further information, see ContainerManagedEvents.
The default value is SOURCEQUEUE.
Delivers request messages that require a synchronous response from the connector framework to the broker. This queue is necessary only if the connector uses synchronous execution. With synchronous execution, the connector framework sends a message to the SynchronousRequestQueue and waits for a response back from the broker on the SynchronousResponseQueue. The response message sent to the connector bears a correlation ID that matches the ID of the original message.
Delivers response messages sent in reply to a synchronous request from the broker to the connector framework. This queue is necessary only if the connector uses synchronous execution.
Specifies the time in minutes that the connector waits for a response to a synchronous request. If the response is not received within the specified time then the connector moves the original synchronous request message into the fault queue along with an error message.
The default value is 0.
Message format on the transport.
