Overview

If you associate a command script template with a task in your migration project, gmStudio will find it, edit processing parameters, and run it at key execution points during batch processing:

Pre/Post Translation
Pre/Post Deployment
Pre/Post Build
Functional Test Task

For example, one use of this facility might be to install the new system in a test environment and run a series of automated tests after each build.

Execution of the Batch Command Script

If a batch command script is associated with an upgrade task, it will be executed along with the major batch operations. For example, during the deploy operation, gmStudio executes the following command line:

cmd.exe /C pushd "C:\gmSpec\Lang\OverloadArg\proj\log" 
&& "migName-task-tag-lang.userCmdBatch.cmd" PRE-DEPLOY >"migName-task-tag-lang.bnd.log" 2>&1 
&& "C:\Program Files (x86)\GreatMigrations\gmStudio\\support\tools\deploy.exe" "migName-task-tag-lang.bnd" replace verbose >> "C:\gmSpec\Lang\OverloadArg\proj\log\migName-task-tag-lang.bnd.log" 2>&1 
&& "migName-task-tag-lang.userCmdBatch.cmd" POST-DEPLOY >>"migName-task-tag-lang.bnd.log" 2>&1 
&& popd
 
The command line executes five operations:
1) Make the workspace log folder the working folder
2) Run the batch command script passing PRE-DEPLOY 
3) Run the deployment tool
4) Run the batch command script passing POST-DEPLOY 
5) Reset the working folder

The standard and error output of the batch script is joined with the output generated by the associated batch operation.

Structure of the Batch Command Script

The batch command script is a text file written in Windows Command Script syntax and executed by the Windows command shell. Windows environment variables are also available to the batch command script.

The batch command script is a template file: it supports an extensive set of parameter variables (i.e. %parameter%) that will be replaced by actual values associated with the upgrade project/task to create an actual batch command script. The replacements produce the Actual Batch Command Script in the workspace\log folder. That Actual Batch Command Script is executed before and after the associated batch operation being performed by gmStudio. A listing of the actual batch script in the log folder may be viewed at the bottom of the Deploy Log display on the Information panel.

The default batch command script template is organized into sections using statement labels. The different sections are executed based on the command line parameters passed when the script is executed.

Batch Command Output

The console output generated by the batch process will be joined to the logs associated with each main batch operation. These logs can be reviewed in the by Clicking the appropriate buttons on the Information Panel.

The log from the TEST operation may be viewed at the bottom of the Build Log Text display.

Activating a Batch Command Script

The UsrCmds field on each task record is where you specify the name of your batch script template. You will not typically specify the full path to your batch file, rather you will specify just the filename then place the script in the workspace\usr folder.

The steps to associate a batch command script with an upgrade task are as follows:

Click the task you want to add user batch handling for
Client Edit Task Attributes in the Task Context menu
This will display the task information editor
Enter the name UserCmd.cmd in the UserCmd field
Click Save
The tool will copy a default UserCmd.cmd from to your workspace\usr folder if one is not already there.

Editing a Batch Command Script

Once you have associated a batch command script with a task, clicking [Edit Task Script(s)] on the Task context menu will open the file in the editor along with the main translation task script.

Sample Batch Command Script

A listing of a sample batch command script template is shown below. Notice there are examples of the script parameters and labeled sections that correspond to the different execution points.

This particular script has code in the TEST section which executes the .NET binary and compares its output with the output generated by running the VB6 code.
