Configure the WebSphere MQ Non-Intrusive agent

This task describes how to configure the Service Virtualization IBM WebSphere MQ Non-Intrusive agent, configure your WebSphere MQ Server, and virtualize MQ communication.

In this topic:

Overview

The Service Virtualization WebSphere MQ Non-Intrusive agent enables you to virtualize WebSphere MQ communication without the need for any reconfiguration of your applications under test. You need only to deploy several libraries to the MQ server and reconfigure a queue manager. No virtual queues are required.

In Standby and Learning modes, messages come untouched through the MQ server, but Service Virtualization is receiving message copies.

In Simulation mode, messages are processed by Service Virtualization while the real service is still running, but the real service does not receive any communication.

Configure the Service Virtualization agent

1. Configure the Service Virtualization agent settings

   From the main menu, select Tools > Options. On the Agents Page, select WebSphere MQ Non-Intrusive. For user interface details, see the WebSphere MQ Non-Intrusive agent settings.

2. Optional: Perform additional global configuration

   You can configure additional settings using the Service Virtualization configuration files.

   1. Open the appropriate file:

      • Standalone Server configuration file on Windows:

        %[INSTALLLOCATION]%\Server\bin\HP.SV.StandaloneServer.exe.config

      • Designer configuration file on Windows:

        %[INSTALLLOCATION]%\Designer\bin\VirtualServiceDesigner.exe.config

   2. You can define the following element in the appSettings section of the configuration files. This configuration element sets up global behavior for processing WebSphere MQ messages.

      • <add key="MQAgent.DefaultCharacterSet" value="0"/>

        Configures the default character set for simulated XML responses. Use this configuration if the character set is not recorded as message metadata. If the value is set to 0 the character set is not set.

Agent limitations

• The WebSphere MQ Non-Intrusive Agent instance can only use queues from a single Queue manager.

• The WebSphere MQ Non-Intrusive Agent instance can only use a single TCP channel to connect to the Queue manager.

• CCSID configuration in the WebSphere MQ Non-Intrusive Agent instance requires an application restart.

• CCSID configuration is global for whole the application. There cannot be two agents with different CCSIDs.

Configure the WebSphere MQ server

1. Extract the Service Virtualization MQ API Exit libraries.

   After you install Service Virtualization, the libraries are in the following locations:

   Designer	C:\Program Files\Micro Focus\Service Virtualization Designer\Tools\WebSphere MQ Extensions\HP.SV.WebSphere_MQ_API_Exits.zip
   Server	C:\Program Files\Micro Focus\Service Virtualization Server\Tools\WebSphere MQ Extensions\HP.SV.WebSphere_MQ_API_Exits.zip

2. Unzip the file and copy the appropriate SV MQ API Exit libraries to the following destination folders on your MQ server.

   Solaris	From <extracted root>/<solaris version>/32bit to /var/mqm/exits From <extracted root>/<solaris version>/64bit to /var/mqm/exits64
   Windows	From <extracted root>\<windows version>\32bit to C:\Program Files (x86)\IBM\WebSphere MQ\exits From <extracted root>\<windows version>\64bit to C:\Program Files (x86)\IBM\WebSphere MQ\exits64
   HP UX	From <extracted root>/<hpux version>/32bit to /var/mqm/exits From <extracted root>/<hpux version>/bit to /var/mqm/exits64
   IBM AIX	From <extracted root>/<AIX version>/32bit to /var/mqm/exits From <extracted root>/<AIX version>/64bit to /var/mqm/exits64

3. Enable the TCP/IP port.

   Enable your firewalls to connect from the MQ Server to the Service Virtualization Server on a port that you specify. This port must be the same port you use in the Service Virtualization WebSphere MQ Non-Intrusive Agent settings, in the Non-Intrusive Server Port field, as defined in step 2 above.

   Note: If the Service Virtualization WebSphere MQ Non-Intrusive Agent is not running and Service Virtualization Server is protected by Windows Firewall, you might experience slow performance. This is caused by the fact that the SV MQ API Exit library can not communicate with the Service Virtualization Server. This can be resolved by disabling Stealth Mode in Windows Firewall. For details, refer to Microsoft documentation.
   

4. On the MQ Server, update the queue manager configuration.

   Append the following lines to your queue manager configuration file. By default, the file is located on the MQ Server in <WebSphere MQ root>/qmgrs/<your QM>/qm.ini.

   Note: The Data parameter is limited to a maximum of 32 characters.

   Solaris, HP UX, AIX:

   ApiExitLocal:

   Module=sv_mq_api_exit

   Function=Init

   Name=SV

   Sequence=100

   Data=<Service Virtualization hostname or IP>:<Service Virtualization TCP/IP port>

   Windows:

   ApiExitLocal:

   Module=SvMqApiExits.dll

   Function=Init

   Name=SV

   Sequence=100

   Data=<Service Virtualization hostname or IP>:<Service Virtualization TCP/IP port>

   Where:

   • <hostname or IP address> = Hostname, DNS, or IP address of the Service Virtualization machine, such as example.com or 192.168.0.2.

     Note: Raw IPv6 addresses are not supported. As a workaround, you can map the IP address to a hostname in the machine's hosts file , and then use the hostname in the qm.ini file.

   • <TCP port> (mandatory) = The TCP port of the Service Virtualization agent, such as 5500 or 5000.

   For additional configuration parameters, see Additional queue manager configuration options.

5. Stop and then restart your queue manager. On a Windows system, you may need to also stop and restart the IBM MQ system service.

Additional queue manager configuration options

You can define additional configuration parameters in the queue manager configuration file for debugging and timeout settings.

In qm.ini, configure the Data section of MQ API Exit definition in the following format (up to 32 characters):

Where:

• <timeout> (optional) = The TCP connection timeout value, according to the table below.

• <loglevel> (optional) = The log level of the API exit, according to the table below.

  Note:
  • The logs can consume large quantities of your disk space. This feature should be enabled for debugging only, and should be turned off by default.

  • When logging is enabled, log files with the pattern sv_mqexit_*.log are created. Those files are placed in the following folders on the MQ server machine:

    • Windows: The default temp folder C:\temp.
    • UNIX: The default temp folder /tmp.

    You must assign write permissions for MUSR_ADMIN and other MQ-related user accounts in order to successfully generate log files and prevent the exit from crashing.

Create a new virtual service

Create a new virtual service, and select the appropriate WebSphere MQ Non-Intrusive option for your messaging protocol. For user interface details, see Create New Virtual Service Wizard.

You can now virtualize any request/response queue pair from the queue manager.
