I’ve written some scripts to automatically export all your unsealed management packs if there is something changed, write a version number and email the new managementpack with a summary of all differences.
Another script will import your version controlled management packs (if there is something changed).
Scripts are updated on 12-11-2009
To setup version control for Management Packs, you need the following:
- ExportUnsealedMPs.ps1
- ExportUnsealedMPs_Simple.ps1
- ImportMPs.ps1
- SCOMSettings.xml
- A folder structure to save management packs
- SVN and TortoiseSVN
Folder Structure
SVN\SCOM
Scripts
SVNControlledMPs
UnsealedMPs
– diff
– temp
– test1
– test2
SVN
SVN is needed to do commits directly from within the script. TortoiseSVN helps you to commit, update and compare files within the Explorer.
Setup
After you setup SVN and Tortoise SVN and created the folder structure. You can create scheduled tasks to run the import and export jobs. It is a good idea to run the export at the end of the day to capture all changes of that day, I export them at 19:00.
Best time to import the management packs is 13:30, you don’t want to get suprised at night if some import causes pages.
First run ExportUnsealedMPs_Simple.ps1 to get all unsealed management packs without version control.
Commit your Unsealed Folder in SVN (before you do that, make sure you have marked xml files as text:
Edit Tortoise Settings file, add the following lines
Under [miscellany]:
enable-auto-props = yes
Under [auto-props]:
*.xml = svn:mime-type=text/xml;svn:eol-style=native;svn:keywords=Rev Date
Run the export job, it should not export anything, since you are up-to-date.
Change something in a management pack, update a description will do.
Run the export job again, you should see it is updated, committed and an email is sent to the address mentioned in your settings file..
