How can i improve my application using this features?

[Rafael P]

Greetings,

Currently, we are working on a application that already has a server setup (Windows Server 2012) loading a project like client-server adopting
IIS and HyperServer (along side uniGUI), and these one's are been configured into DataSnap.

But, a few days ago, my application starts to freezing and crash, and it's necessary to restart them again. uniGUI it's already attached into
HyperSever and stablished correctly into client. By the way, we have DataSnap in Server-Side (case this one will crash) all our services it will stop.

And i would like to know if there's any kind of settings i must be set into my application (or right into Datasnap, maybe?) or really should i search for another
kind of Data Transference which it would be eficient and responsive (more them this one) which i use today?

 

Best Regards!

Hello,

First of all, please tell us which build and edition of UniGUI are you using?

[Rafael P]

Hi Sherzod, 

version uniGUI 1.90.0.1531.

[Sherzod]

Thanks,

If you are not using trial edition, please adjust your forum email address:

 

[Rafael P]

Done. Can you verify now, please? 

[Sherzod]

Yes. Thanks.

[Sherzod]

Are there any errors in the log files?

[Rafael P]

Yes, the log errors will be attached below. These files contains settings of HyperServer. 

If you need some more information, please let me know and i will put them. 

Appreciate!

index.cfg

n1 A2020-07-09.log

n0 A2020-07-09.log

Index.dll A2020-07-09.log

[Rafael P]

Sorry to bother... Did you have find something?

Hi,

[TUniServerModule]:Access violation at address 0078E988 in module 'AgilizaNotaClient.exe'. Read of address 00000064

This is an error in your node log files.

Your Nodes may crash because of this error, but your HyperServer should never crash unless it is configured incorrectly.

Are you deploying HyperServer in DLL form?

[Farshad Mohajeri]

If it is a DLL make sure your Pool is runs under LocalSystem account.

[Rafael P]

Hi Farshad and Sherzod, is great to have some answers from you sirs! 

So, you have looked in a point at, meanwhile, we don't take the right attention to it. 

All the times that a node need to be restarted, the error will ocurred along trying to take down the service. 

By the way, it's not in this kind of situation that system's will freeze, but this starts to show that will came to be a prelude that something's gonna wrong. 

Will be attached below a file system's that keep our setting's on it. Please verify that.

Actually we are deploying the application using .exe file, but indicating on him into the IIS using HyperServer Index.dll.

Today, we have 4 applications loading into this server, and all of these ones are using HyperServer:

• Relation Http_Transport:

- App 01:  start_port=16384 - (it's gaining more access, and most of the times it would be crashing once per day);
 

All the other ones don't freeze, but the gain flux access is less than the other i have mentioned before:

• App: start_port=16994 
• App: start_port=17604
• App: start_port=18214

 

index - new.cfg

Hi again,

we are informing on IIS our administrator account.

[Farshad Mohajeri]

Hi,

I am referring to this setting:

http://www.unigui.com/doc/online_help/index.html?hyperserver-isapi-module-mode.htm

[Rafael P]

These are our settings. Please can you tell me it's only necessary change Identity to LocalSystem? 

[Farshad Mohajeri]

Administrator is OK.

[Wilton Ergon]

I would have already left datasnap, use restdatawhere, and totally free, and much more stable than datasnap

Sorry to persist on this... But, analyzing the index file, is there any kind of setting i must change on it?

Really appreciate any help!

[Farshad Mohajeri]

Hi,

Your CFG file seems OK.

You should stress test your EXE  against stability issues.

@Rafael,

1. Also, take care of Memory Leaks !

I had in the past this issue which was crashing the server. You can test with FastMM4.

2. An other point,  i did'nt understand : why are you using DataSnap ? 

(With Unigui you don't need this buldozer, as all is server side).
