Sorry, what is 'db sfn'?

Super. Thanks for that great tip!!

Yes both TESTTC01 and TESTTC02 existed.

Yes the process seems overly complicated but these were from some notes left by my predecessor

Thanks for your advice

Thanks

Thanks for the advice

I was running this from terminal - understood.

Thanks again.

set status=##Class(SYS.Mirror).AddDatabase("/db/iknow")

I get a syntax error when I do:
IF $$$ISOK(status) {w "OK"} else {w "not OK"}

Although this works OK:
IF status {w "OK"} else {w "not OK"}

Any idea why this is so?

Thanks for the fast reply

Thanks for the suggestion.

You mentioned "InterSystems internal interactive tools. So, most such tools have non-interactive endpoints".

Could you please provide an example?
Is there a listing of all such "tools"?
