Using IBM WebSphere MQ Adapters with Ensemble
Settings for the IBM WebSphere MQ Adapters
Provides reference information for settings of the IBM WebSphere MQ adapters, EnsLib.MQSeries.InboundAdapter and EnsLib.MQSeries.OutboundAdapter.
For both the inbound and outbound adapters to IBM WebSphere MQ, you specify settings that describe the connection to a given queue. The details are nearly identical for both adapters.
Specify values for the following settings in order to specify the message queue of interest, the queue manager to use, and the channel to use:
(Required) Specifies the queue name; this should be a valid queue for the specified queue manager. Also, you must have permission to use this queue.
Specifies the queue manager; this should be a valid queue manager on the IBM WebSphere MQ server and you must have permission to use it.
If you omit this setting, the system uses the default queue manager, as configured in IBM WebSphere MQ. Or, if IBM WebSphere MQ has been the configured so that the queue manager is determined by the queue name, the system uses the queue manager that is appropriate for the given queue name.
The specification for the channel, in the following form:
is the name of the channel to use, transport
is the transport used by the channel, host_name
is the server name (or IP address) that is running the IBM WebSphere MQ server, and port
is the port that this channel should use.
If you omit this setting, the system uses the default channel specification, as configured in IBM WebSphere MQ. Or, if the system has been the configured so that the channel is determined by the queue name, the system uses the channel that is appropriate for the given queue name.
Use the following setting to specify the log file to write to.
Specifies the log file to write error messages to. If you omit this setting, no logging occurs.
You can specify the character set to use for message conversion.
Specifies an integer Coded Character Set ID (CCSID) as used in IBM WebSphere MQ.
For the inbound adapter, this is the character set to convert the messages to. If you do not specify a character set, the MQ system assumes the messages use the default character set specified for the MQ client.
For the outbound adapter, this setting specifies the character set that the messages are already in; no conversion is done.
This applies only to the inbound adapter. To specify how often to check for messages, use the following setting:
Number of seconds that the adapter will wait before checking again for new messages, before checking for a shutdown signal from the Ensemble framework.
If the adapter finds input, it acquires the data and passes it to the business service. The business service processes the data, and then the adapter immediately begins waiting for new input. This cycle continues whenever the production is running and the business service is enabled and scheduled to be active.
The default CallInterval
is 5 seconds. The minimum is 0.1 seconds.
The examples in this book used an IBM WebSphere MQ server running on a machine named antigua
, using the port 1414. The user ID under which the examples were run was authorized to use the queue manager QM_antigua
and a queue named cachetest
. Ensemble used a TCP channel named S_antigua
to communicate with the server. The following table lists the settings:
