WebSphere MQ agent settings
This dialog box enables you to configure the Service Virtualization WebSphere MQ agent. The agent handles communication between a client and a real or virtual service.

User interface elements
User interface elements are described below (unlabeled elements are shown in angle brackets):
UI Element | Description |
---|---|
<left pane> |
Displays the server configured for your project. Expand the server to display the available agents and configurations. |
Add |
Enables you to define additional configurations of the agent. |
Delete | Deletes the selected configuration. |
Duplicate |
Creates an additional configuration of the agent by copying the selected configuration. You can then modify the configuration settings. |
Export |
Saves the selected agent configuration as a file. The file is saved in the .agce file format, and can be imported to any Service Virtualization Server. |
Export All | Exports all agent configurations on the selected server. The file is saved in the .agce file format, and can be imported to any Service Virtualization Server. |
Import |
Enables you to select an exported agent configuration file stored on the file system. The file is saved in the .agce file format, and can be imported to any Service Virtualization Server. If the configuration file you are importing contains multiple configurations, you can select which configurations you want to import. If you choose to import an agent configuration that is identical to a configuration that already exists on your server, you can choose to overwrite your existing configuration, or create a new, additional configuration. |
Agent State | The current status of the agent. Values include Running, Not Running. |
Test Configuration link | Tests the configuration based on the settings you select. If Service Virtualization identifies any problems in your configuration, the details are displayed. |
Is Enabled | Turns the agent on and off. To enable the agent, the prerequisites must first be met. |
Name | Enter a name for the agent instance or accept the default name. |
Local Connection |
If the Service Virtualization Designer or Server is running on the same machine as the WebSphere MQ server, you can use a direct local connection to the MQ queue manager. Using the local connection may have a positive impact on performance and simplifies agent configuration. Local Connection allows direct connection to the queue manager specified by the Queue Manager Name property If you select this option, you do not need to configure the Host, Port, Channel Name, or SSL properties. |
Queue Manager Name |
The name of the queue manager for the agent to connect to. This option is necessary only if Local Connection is used. |
Channel Name |
The name of the TCP channel for the agent to use to connect to the queue manager. |
Host |
The name or IP address of the server hosting the queue manager. |
Port | The TCP port where the channel listens for client connections. |
CCSID |
The character set used by the host. It may be optional depending on the WebSphere MQ configuration. |
Username/Password |
The username and password for connecting to the queue manager. These values may be optional depending on the MQ channel configuration. For details, see MQ authentication. |
SSL | |
SSL Protocol | Secure protocol used for the MQ Server connection. For details, see SSL Configuration. |
MQ Channel Root CA File |
Path to a certificate file of the Root Certificate Authority which signed the SSL certificate bound to the MQ channel, or to a self-signed MQ channel certificate. Supported formats are Base64 PEM, and binary CRT (supported on Windows only). This certificate is added to the 'Trusted Root Certificate Authorities' certificate store. If the Service Virtualization Designer and Server are run "as Administrator", it puts the certificate in the Local Machine store; if the Designer is run as a non-admin user, it puts the certificate into the Current User certificate store. You can leave this property empty if the MQ channel certificate is already trusted by a machine running Service Virtualization. |
Thresholds | |
Max. Connections | The maximum number of cached connections to the queue manager allowed for handling messages. More connections enable more messages to be sent concurrently. |
Advanced Settings | |
Message Context Mode |
Options for accessing the MQ queue. See the WebSphere MQ documentation for details.
|
Strip XML Declarations | Removes XML declarations (<?xml ...>) from text messages before processing in Service Virtualization. Text messages are in Unicode. |
Use UTF Methods |
Service Virtualization considers MQ text messages as created by the WriteUTF() method instead of the WriteString() method. When using an XML service, the message can be either transferred as a string (with a specified character set) or as binary data (UTF). By default, the agent reads and writes messages as a string. Select this option to use binary messages with UTF content instead. |
Response Queue Access Mode |
Defines how Service Virtualization opens the response queue.
|
Listening Timeout (ms) |
The length of time Service Virtualization listens for a response or multi-response. If the response does not arrive within the timeout period, Service Virtualization stops the listening process, even if there are multiple responses expected. |
Maximum Responses per Request | Defines the number of response messages that are expected for each request message. Relevant when the Service Virtualization agent is configured to use Shared Response Queue Access Mode only. When the maximum responses per request are reached, Service Virtualization stops the listening process. |
Request-Response Matching Mode |
Defines the method used to match a response to the correct request.
|
MQ authentication
The MQ Queue Manager can use two methods of authentication:
-
MQCSP authentication. To use this method, you enter the credentials into the Username and Password fields. These credentials are managed by the MQ administrator.
-
Authentication via the local user running the SV process. The MQ Queue Manager can be configured to use this method in addition to or instead of MQSCP authentication. When using this method, you leave the Username and Password fields empty.
Tip: You can configure the SV process to run under a dedicated user, to make it easier to grant user permissions. For details, see How to run SV Server under a different user.
For both authentication methods, the MQ administrator manages the permissions for the virtual agent. If you are granted certain permissions, you can browse and search Websphere MQ queues and create or delete virtual destinations. For details, see WebSphere MQ and Browse Destinations Dialog Box.
To browse MQ destinations, the specified user must be able to perform the following in the WebSphere MQ client:
-
put and inq operations on the SYSTEM.ADMIN.COMMAND.QUEUE
-
get, inq, and dsp operations on the SYSTEM.DEFAULT.MODEL.QUEUE
-
dsp operations on queues to which the user has access permissions
To create or delete a virtual destination, the user requires additional permissions, such as administrator permissions. For details, contact the MQ administrator.
