Using IBM Rational Synergy Keywords in esql files

There are two different keyword forms that can be used in an objects source, the %keyword% form and the %keyword:% form. The %keyword% form permanently replaces the keyword with the attribute value when you initially create the object. The %keyword:% form is appended with the attribute value each time you create or check out/in the object. Also the %keyword% form is completely replaced in the object when expanded, but the %keyword:% form in only partially replaced; the keyword itself still remains in the object.

More informations can be found here

To use a Synergy Keyword in an esql file one can use it in a comment. Example:

-- %name: % %version: % %date_created: %

Message Broker Application Development – How to create a SOAP Fault in ESQL

mqsicreatebar command not giving any reponse

If you not getting any response from the command mqsicreatebar you can have a look at the log file whitch will be created in the Workspace directory, e.g. E:\MessageBrokerToolkitWorkspace\.metadata\.log.

You can also add the -cleanBuild parameter to refresh all the workspace projects and invoke a clean build or delete the .metadata directory.

Creating a bar file with mqsicreatebar

To create a bar file one can use the mqsicreatebar command:

C:\Program Files\IBM\WMBT700>mqsicreatebar -data <absolut_path_to_workspace_directory> -b <name_of_bar-file_to_create_or_replace> -p <projects_containing_files_to_include_in_the_bar_file_in_a_new_workspace> -o <workspace_relative_paths_of_the_resource_to_be_added>

If you have made changes to resources in the broker archive by using external tools, add the -cleanBuild parameter to refresh all the workspace projects and invoke a clean build.

If you want better output of the command, try the -debug and -trace switches.

Example:

C:\Program Files\IBM\WMBT700>mqsicreatebar -data E:\MessageBrokerToolkitWorkspace -b E:\MessageBrokerToolkitWorkspace\MyProject\MyFlow.bar -p MyProject -o MyProject\MyFlow.msgflow -cleanBuild -trace

WebSphere Message Broker Toolkit v8 introduces the ability to deploy message flows without needing to compile them into *.cmf files and the same feature is used by the mqsipackagebar command.

With the mqsicreatebar command one can compile the resources like .mset to .dictionary and .java to .jar before using the mqsipackagebar command by using the -compileOnly parameter.

Adding Remote Message Broker using .broker file

  • Stop the Message Broker Toolkit
  • Add the configuration file (.broker file) in Message Broker Toolkit workspace:
    <YOUR_WORKSPACE>\.metadata\.plugins\com.ibm.etools.mft.broker.runtime\
  • Start the Message Broker Toolkit again

The user environment was not adequately prepared to continue execution.

If you try to run a command like ‘mqsireportproperties'and got the error below you need to run mqsiprofile BEFORE you run your command.

The user environment was not adequately prepared to continue execution. Locate and run the profile supplied with the product. This file is called mqsiprofile, and is located in the bin subdirectory for the product.

SET "BROKER_HOME=C:\Program Files\IBM\MBroker\7.0"
SET "path=%path%;%BROKER_HOME%\bin"
