SIMS slow in RDSA2019

[mhaddon]

Clutching at straws here but hoping someone might know of a tweak that we're missing.

 

Migrating from RDS2012 to RDS2019 and testing SIMS as a published app. It's generally ok. Few seconds between clicking icons etc. But when you click the staff and/or student icons for the first time it can take several seconds before opening those pages. Sometimes the screen flickers and and sometimes we get a not responding message in the SIMS app.

 

Strangle enough we don't seem to get these issues when logging onto the session host server and launching SIMS locally.

 

We also don't seem to get these issues when logging onto a published desktop and launching SIMS from the desktop.

 

The session hosts are pretty beefy so we don't think it's a server sizing issue. Other published apps, including FMS, all seem to work fine.

 

Only other consideration is that we have installed SIMS onto a D: drive on the session host because the disk can fill and bring down the server when installed on C:. We did create the SIMSLink virtual mapping though so that the app knows where it is.

 

Struggling to fault find this one. Not even sure what process is called when you hit those buttons to see if something could be timing out but it's just strange that this only seems to happen with the published app.

Please check the SIMS.ini file when you access RDP and make sure no resources from local machine is redirect when using RDP.

Server 2019 would need considerable high resources to run SQL. That will normally shower the clients. It's not the case for you.

thanks for the suggestion. i'll have a look

There are two SIMS.ini files

 

one with redirect from my documents of the logged in user

Other one is in Program files\Windows

 

If you have resources please upgrade to Server 2020 and that seems a stable OS than 2019.

Don't do this - SIMS isn't officially supported on Server 2022 yet

If you publish a full desktop (via .rdp or the HTML5 webclient) does SIMS also behave erratically?

 

(We're trying to nail down whether launching SIMS as a remote user is a problem, or whether launching SIMS as a published application is a problem).

Seems to work fine if you run it from a published desktop (.rdp) but if you run it as a published app (.rdp) then these 2 functions (Staff and Student) are slow, the screen sometimes flickers and sometimes you get a Nor Responding message. I think my colleague also tested the published app through webclient and that had the same issues.

But your posted picture shows support from summer 2024 onwards - and in SIMS release chronology aren't we on it now?

No it's still the spring release - Summer upgrade usually comes out in July.

hmmm. Issue went away for a few days and then came back with no changes to the RDS environment. Starting to wonder if it's the SQL backend (which is on a separate SQL box). Also wondering whether it could be a pc issue e.g. AV kicking in but it's strange that it's only when you hit those 2 buttons. I think those buttons open up a query form for students or Staff though without actually doing anything? Dunno if that's just calling a saved form or something like that? I don't really know anything about SIMS
