I would caution against using the management portal to rebuild indices on a live system. Please see the word of warning from the documentation you linked:

https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=GSQLOPT_indices#GSQLOPT_indices_build_smp

"Do not rebuild indices while the table’s data is being accessed by other users. To rebuild indices on an active system, see below."

Further along on the page you can find more information about safe index rebuilding practices on a live system. I would recommend sticking to %SYS.Maint.Bitmap as that is safe to run on an active system.

Hello Stephen,

That documentation you linked to put you on the right track! If you click on the %SYS.Maint.Bitmap link it will take you to the class reference which contains some examples of how to run the bitmap cleanup:

https://docs.intersystems.com/latest/csp/documatic/%25CSP.Documatic.cls?PAGE=CLASS&LIBRARY=%25SYS&CLASSNAME=%25SYS.Maint.Bitmap

eg.

d ##class(%SYS.Maint.Bitmap).Namespace("Samples",1,1,"2014-01-17 09:00:00")

d ##class(%SYS.Maint.Bitmap).OneClass("BitMap.Test",1,1)

This utility was only added to the product around version 2015, I believe. It should run automatically as part of an Ensemble message purge. If you need to perform this maintenance on an older version, rebuilding the index can be done though this is a more involved process, especially on a live system.

If needed, you can reach out to the WRC who can provide a utility that performs a similar function to %SYS.Maint.Bitmap for older versions.

Hope that helps!

If you see an error message in brackets, this documentation would be a good place to look to find out what it means:

https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=RERR_system

<FILEFULL> can indicate issues with the actual disk filling up, but you can also run into it if you have configured and reached a maximum database size.

You can check that setting in the management portal at System Administration > Configuration > System Configuration > Local Databases, or you can use the ^DATABASE utility as documented here:
