TDLite (CMIExplorer)
Note:
This document is a work in progress, we're posting it in it's present (and workable) state to help unblock customers ASAP, your feedback via the blog's contact link at the top of the page would be greatly appreciated.
TDLite (aka CMIExplorer) comes as a tool in the Value Add folder on your XP Embedded tool kit. For the purpose of this document it will be assumed that CMIExplorer is already installed on your XP Embedded build machine in the %ProgramFiles%\windows Embedded\utilities folder. You can use this tool to perform a lot of the core actions you can with Target Designer and DBMgr: Create a config, add/remove components to the config, import/delete components from the DB, resolve dependencies and build the configuration.
TDLite is a command line tool used to interact with CMI. It provides a simple shell that executes commands entered either on the command-line, interactively, or read from a response file.
This document covers a couple of the commands that can be used with cmiexp.wsf to perform operations such as build a runtime, check dependencies, check the dependency tree of a component etc. More to come later.
Usage:
The typical usage pattern for CMIExplorer looks like
CMIExp [macros] ["cmd" | @respfile ] ... [switches]
More information regarding each of these arguments can be found in the CMIExplorer help. To check this, you can run the command cmiexp.wsf /? at your command prompt.
If no command-line commands are specified, CMI Explorer will enter interactive mode, and read commands from the console. Each command is prompted for with a "*" prompt and executed immediately. For ex:, at the command prompt type cmiexp.wsf , you will see:
Microsoft (R) Windows Script Host Version 5.6
Copyright (C) Microsoft Corporation 1996-2001. All rights reserved
CMI Explorer version 3.14.620 (CMI revision 578)
Copyright (C) 1999-2001 Microsoft Corp. All Rights Reserved.
Platform GUID : {B784E719-C196-4DDB-B358-D9254426C38D}
Platform : (not in database)
*
You can now type your CMI commands at the “*” prompt.
CMI Explorer Response file
CMIExplorer can accept a response file as an input. This response file can contain the commands you want CMIExplorer to execute. It typically ends with a “res” extension. Each of these commands should appear on a single line in the response file. The CMIExplorer command to use with response file is...
cmiexp.wsf @myResponseFile.res
...where myResponseFile.res is the response file containing the commands that need to be executed.
Example of how a myResponseFile.res looks like is shown below (in the scripts below, 'myDatabasename' refers to your own DB Server name):
dbopen myDatabaseName
new c1 = 'comp:Fujitsu DL 5600'
deptree /2 c1
dbclose
quit
Note that you can also enter each of the commands interactively at the CMIExplorer * prompt to achieve the same results.
More information on each of these commands can be found in the later sections of the document.
The typical sequence of commands to be used with CMIExplorer is:
1) Open a database connection
2) Execute CMI commands
3) Activate the configuration, if you want to build, check dependency, or add a new component to an existing slx. This is a very important step which commonly gets missed.
4) Execute CMI commands if any
5) Close the Database connection
6) Quit
Note: Outlined below are a couple of sample CMIExplorer response files.
Finding the dependency tree of a component
dbopen myDatabaseName
new c1 = 'comp:Fujitsu DL 5600'
deptree /2 c1
Description of the above .res file:
Dbopen opens a database connection to myDatabaseName. The next command is basically creating a new CMI object of type comp which holds the name of the component I want to check the dependency . deptree is the command used to check the component dependency tree.
Notes:
You can control the level of dependency information you want to be dumped by changing the number from 2 to higher number. The numbers supported are 0 -7. More information on this command can be found by typing deptree /?
Building an image form an SLX file
dbopen myDatabaseName
new cfg Config
cfg=CMI.CreateFromFile("pathToMySLXFile")
cfg.activate
cfg.build 0, "pathToBuildImage"
dbclose
quit
Description:
An SLX file in CMI terms is nothing but a configuration. So to build an image, you first create a CMI Config object and point it to your SLX file. pathToMySLXFile looks like c:\winlon.slx. This path can also be on a network share. Cfg.Activate activates the configuration. Cfg.build builds the image in the folder you specified within the double quotes “ “. For ex:, pathToBuildImage can look like c:\buildfolder. Make sure this buildfolder is empty.
Notes:
1) Ensure that the build folder you specify is empty. CMIExplorer won’t clean up the folder if it is non-empty at this point. It will bail out with the following error
Error 1003 (0x3EB) in "Config::cmiOnBuild": Destination folder for build not empty
2) Do not forget to activate the configuration with cfg.activate before you try to build the image
Add a new component, Check dependency and Build image
dbopen myDatabaseName
NEW cfg Config
cfg=CMI.CreateFromFile("pathToMySLXFile")
cfg.activate
new newinst Instance
newinst = 'inst:.Net Framework 1.1’
cfg.instances.add(newinst)
cfg.checkdependencies(2)
cfg.resolvedependencies(2)
cfg.build 0, "pathToMyBuildFolder"
Dump Config info
dbopen myDatabaseName
NEW cfg Config
cfg=CMI.CreateFromFile("pathToMySLXFile")
dump cfg
