Finding the RES Workspace Manager Run Once GUIDS

Following on from the initial post on the Run Once Per Computer and Run Once Per Computer, Per User  GUID locations for the .ONCE files, it’s probably wise to let you know how to correlate the GUIDs used with their corresponding configuration items. There is no exposure to the GUIDs directly within the RES Workspace Manager GUI so to find these GUIDs we have to dig into the client database cache (there is a RES KB article but I can’t find it in the portal due to the search engine!).

All RES Workspace Manager agents download and cache a complete copy of the configuration database tables in the %RESPFDIR%\Data\DBCache\Objects folder as .XML files. In here are lots of files correlating to the configuration database tables within the database. The key to this process is to know what files you’re looking for! Here is a list of which files correspond to which object in the database that we’re interested in:

.XML File Object
apps.xml Applications (Notifications)
inst_mail.xml Email Templates
pl_reg.xml Registry Settings/Policies
pl_task.xml External Tasks

Armed with this information we can crack open the relevant file (pl_tasks.xml in this instance) with your favourite text/XML editor and perform a search for the “<runoncefile>” string to locate the relevant GUID.

To delete the .ONCE file for the “Per User Computer” external task, we need to delete the 132DBDF_34930_105A_TASK.ONE file from the %RESPFDIR%\Data (as it’s a related to the computer and not the user!) directory.

Note: @RESGuru has also pointed out that you can locate the relevant .ONCE files by exporting the item in question to a Building Block and then inspect the resulting .XML file. Thanks, Iain

RES Workspace Manager Run Once Per Computer, Per User

We all know that RES Workspace Manager stores the flag that determines if a Run Once task has completed for a given user in the \PWRMENU folder (at least by default). These files are named with the .ONCE file extension and given a (seemingly random) GUID, i.e. <SeeminglyRandomGUID>_task.once.

Unfortunately, there is no simple way of determining which .ONCE file relates to which task but that’s a post for another day! To force a task to rerun for a given user all we need to do is delete the relevant .ONCE file and the task will magically rerun. This avoids the necessity to check the “Clear History” checkbox and force it to run again for all users.

What about the Run Once Per User, Per Computer and Run Once Per Computer options? Logically they don’t live in the user’s \PWRMENU folder as they’re not a per user setting. So where do they live? After a discussion with RES Support it was discovered they live in the %RESPFDIR%\Data directory. Once you’ve determined which file relates to which task you can just delete it!

Here is an example of a Run Once Per Computer and Run Once Per Computer, Per User external tasks:

The 132DBDF_34930_105A_task.once file is a Per Computer external task. The 132DBDF_34981_1381_<domain>_<username>_task.once files are the Per Computer, Per User tasks for the LAB\Administrator and LAB\LOCAL01 user accounts.

Easy when you know how! Iain
