Adjust startup parameters using promon or _DbParams VST

Ran into a pickle - added - SQLWidthUpdate ON in on a 11.6 database and having some performance issues.

Reading that it should be possible to update the parameter with the database online: Progress Documentation using either promon or _DbParams VST. I'm not seeing option 16 - adjust startup parameters under R&D / 4 in promon.

The last option on the menu is 11. Does anyone know in which version this was introduced?

If it's not available, is it still possible to update _DbParams, and if so, how to go about it - haven't found any good docs on it yet ?


Querying the DBParams table seems to indicate this paramater can't be modified???

DbParams-Id DbParams-Name DbParams-Value DbParams-dtype
DbParams-Desc
DbParams-Msg-Num Default value Modifiable DbParams-Misc

(We can't upgrade Progress to a later version because of the application that's running)

You are looking at the 12.2 documentation, so you are seeing promon options you don't have in 11.6.

In 11.6 you should have an _dbparams VST, though it is possible that you don't if your database was created with an earlier DLC and you haven't run proutil dbname -C updatevst since moving to 11.6.

You don't have the ability to adjust all adjustable broker parameters in promon. But you can adjust some values programmatically if you have the _dbparams VST. That said, -SQLWidthUpdate is a parameter that you can't adjust online in your release. You will have to stop the database, adjust the broker parameter, and restart.

I'd be very surprised if there is a valid technical reason why you can't successfully upgrade to 11.7. At least you would be on a non-retired release.
