Previously i saw an article that there was another way to change the configuration but editing the Toad.ini file but that was for Toad version 9. So i thought it would have the same resolution as well.
Not to sure how to change the OS User Name since this is an office laptop and the Toad license was register under this OS User Name(technically belong to my company).
Is there a way to change the OS User Name for a shorter one?
You really ought to pursue the "getting the plan table changed’ route before you mess with your OS Username. Changing the table is by far the easiest solution to this problem. I tried to change my OS Username once and I was left with remnants of the old name - it wasn’t a complete change - it was messy. I ended up changing it back.
The next easiest thing to do would be to upgrade your Toad. Starting in Toad version 10.6, we only take the first 17 characters of OS Username (we add 13 characters to it to form the Statement ID) so you won’t get a “value too large” error if you upgrade your Toad to at least 10.6.
But, if you want to try changing your OS Username, you can do that in Control Panel under “User Accounts”. Change it to something 17 characters or less. I don’t think it will affect your Toad registration, but you might want to check with your IT department first to make sure it won’t cause any problems with their infrastructure.
