I am very close to running my application in production, however, in tests with my team, I am facing some problems with simultaneous access in COM mode. If 2 users perform actions at the same time, this is showing me an ajax error. In file mode this problem does not occur. Does anyone have any idea what it might be? I'm uploading a video of the error.

Hi Arcadio

Congratulation for going to production!

From what I can see (video a little blurred), the error occurs in one of your programs. Please share the full error text so that we can discuss:

use wwRequestLog
browse for error
go bottom
&& locate the error near the end of the log
_cliptext = queryStr
&& the paste here

Thanks! Without help from everyone here on the forum this would not be possible. As for the problem, I realized that it is related to _screen.handle, since the same value is different between users and this is related to the connection to the database. Is there any treatment that I should do specifically for objects _screen ?

The error occurs exactly in this method below where the _screen is different between users.

If I remove a part where it passes through the _screen.handle leaving a fixed value the problem does not occur

Arcadio,

You need to use one handle per server, shared by every users; make sure to set _screen.handle in xxxSets.init() and keep it unchanged; you can exclude it from the custom _screen.properties that FoxInCloud saves automatically for each user like this:

define class xxxServer as awServer
…
_ScreenPropertiesSaveNot = 'handle, …'

Please read the documentation on _ScreenPropertiesSave and _ScreenPropertiesSaveNot in xxxServer.prg

All your remote views or CAD share the same _screen.handle ; eg. with views:

procedure dataEnvironment.OpenTables
…
USE v_ordonnance IN 0 NODATA AGAIN CONNSTRING(_screen.handle) SHARED
…

Gilles has used this technique against a PostGre Database without any issue for almost 10 years.

Cheers

The "handle" property is created in xxxinit and it has different values ??between users. Do I need to inform her in _ScreenPropertiesSave? I had understood that this was not necessary. Only if it has the same value among users should it be informed in _ScreenPropertiesSaveNot. Is my thinking correct or not? Follow below my xxxinit.

It seems that the error is related to the time to update the environment and the connection between users, due to the value of handle being different between them because they are different databases. I includes a "While" in the command that generates the sequential and apparently solved the problem.

OK, I now understand that each user (I guess based on the company he/she belongs to/works for) needs a specific database handle.

As we have no experience with such an architecture I would rather install one site and one application per client company: company1.easysoft.com, company2.easysoft.com, etc., each in a separate folder with a separate EXE; it'd require that you either have one project per company (just for generating specific COM object GUID) or manipulate _VFP.activeProject.GUID programmatically when generating the web EXEs per company.

However, your system should theoretically work fine, for the reasons hereafter.

FoxInCloud restores the application environment, including _Screen.properties, as a VERY FIRST STEP before doing anything on the application; you can see it on the FoxInCloud Web App Dashboard such as this one, column restoring app. state for user.

So, if your server saves _Screen.handle (thus not add handle it to xxxServer._ScreenPropertiesSaveNot as I wrote earlier, before having the full picture), FoxInCloud restores it before querying any view or CAD, and it should always be so.

Of course, as the user can call any master form in any order (using an URL in history), he/she can query a form while having _screen.handle = 0 and get into trouble. To overcome this, you NEED to check that ONLY THE LOGIN FORM (setting _screen.handle for the user) has .wlAnonymousAllowed = .T..

That's all I can tell for now…

Update: a side benefit of having one site and app per company is that it makes it easier to upgrade a company on another server when traffic increases. By merging all companies into a single application you may get into troubles at some point down the road.

Hi Thierry,

I understood what you said. I will think here. However, I don't think I should be no "handle" errors just because of the fact that there are quick actions between different user sessions. As for my idea of several customers using the same installation, this would not be mandatory, it would be just another way of using our app. We are considering all possible scenarios and the scenario of several customers in a single installation would be more possible for smaller customers.

quick actions between different user sessions

whether user actions are quick or slow makes NO difference at all.

User status, including app environment:

• is saved after EACH user action
• is restored before executing user action whenever the current user is different from the previous user on the current server.

Please keep in mind that, in production, you'll run several logical servers (COM/EXE) on the same machine (WC supports up to 32). So users will switch between logical servers.

Arcadio

In this case, what are the reasons why the users of the different client companies would not use the same database with the same PostGresQL handle? This is what I do, I just add in each table a column to identify the company of the connected customer and all my views or SQLEXE commands () use this column to filter the records accessible by the user. This requires, of course, that the data structure of the database is the same for all tables and for all client companies.

Gilles

Hello Giles,

We would have to totally rewrite our software for that. My idea is good as long as it works, since the customer's postrgresql database could in theory be anywhere.

For some reason, if access quickly enters the sessions, the _screen.tipobanco property is going blank and that is the reason for the problem. However, I did not identify the cause of this. It is reported correctly in xxxsets.ini. Follow below the link video with the problem.

Hi Arcadio,

For STRTOFILE(), you should have a different file for each screen, right ?

I used the strtofile to debug, as it is a difficult problem to find. The right thing would be to generate only A.txt and never d.txt and e.txt. Something is erasing the _screen.tipobanco property

It is reported correctly in xxxsets.ini

do you mean xxxSets.init()?

I see no reason why the problem would occur in COM mode and not in IDE mode.

As you know the reason for the problem (empty(_Screen.tipobanco)), you can:

0- to be sure your *.fxp are in sync, do atPJcompile

1- set a breakpoint on this condition (ctrl+B opens the form) :

2- disable the breakpoint, close the debugger and start the server:

3- when your test case is ready (both browsers on the test user and the test form), re-enable the breakpoint and open the debugger:

The program will stop on the instruction that blanks _Screen.tipoBanco.

Just a guess, I suspect an *_assign() method that is not adapted.

Hi Arcadio It is possible that the connection to the database server is busy and that the SQLEXEC () command is not executed by the database. Before launching an SQLEXEC () command, I test the status of the database engine with the BUSY function (at least for PostGresql):

FUNCTION SqlPasBloque AS Boolean

regards Gilles

Perfect Gilles,

I will implement this in my system, Thanks. However the biggest problem is to lose the value contained in the property. Thierry will help me find this out in a private consultation.

Hi Arcadio,

Regarding the ability to switch connection across users, as you use CursorAdapters, you can change .dataSource at run time.

If you really need to do that, I have several possible solutions to be discussed in private support.

The multiple datasource is even working the way I showed in the topic, https://support.west-wind.com/Thread5GN1DN3X5.wwt, I don't know if it's the best way, but it's working. Just informing the datasource in init simply, it didn't work. Perhaps it is related to the same problem as the property "_screen.tipobanco"

Hi Arcadio,

This multi-database handles scenario is quite touchy and I suggest you run full tests (combining all scenarios) before putting it in production.

To make it work you need to swap cursorAdapter.DataSource for each user and one simple way to do that is to make sure that your cursorAdapters are members of form.dataEnvironment and add ”dataSource” to cursorAdapter.wcPropSave.

But again, as we have never experienced such a scenario, it requires heavy testing.

Also, You need to consider the many-to-many relation between servers and users; if a user gets a handle on one server, you’ll need to somehow get him another handle on another server.

To overcome this, I would create a pool of connections with a table between companies, users and handles; upon each request, I would set _screen.handle to what is appropriate to the user and set CAD.dataSource to _screen.handle in CAD.dataSource_assign(), thus ignoring what was saved.

Update: forgot about the 2019 thread you mention. All this is confusing. Please take some time to clearly state your issues. Thanks.

cursorAdapter.wcPropSave.

I'll check that out.

Thanks!
