Prevent parallel sessions

Hi,

one of my customers is facing the problem, that sometimes users are opening multiple WebServices-sessions from multiple browsers.or multiple clients (Version 11)

This can lead to conflicts with global variables and other side effects.

I'm wondering if this can be prevented, so that when trying to open a second session, the user either gets an error like "you are already connected" or that the new connect just takes over the existing session.

Is this a common situation at other companies as well? How do you treat this? Just asking users not to open multiple sessions does not work...

Regards,

Ralf

Hi Ralf,

use a cube flag;

-create a control cube with 2 dimensions (or more if required)

-use a WBC to write a 1 on report load using report actions, use a 'Set parameters' as a action type, the action condition is usually set to true by default you can change this to an if statement, eg if(rwc<>1, true, false)

-create a second action, this time a jump, the action condition is usually set to true by default you can change this to an if statement, eg if(rwc=1, true, false)

-jump to a report designed like a error dialogue box

-key step here is capturing when you have left the report to then write a 0/null to the cube slice, can use a close button with an action to store this that simply jumps to the previous report.

Hi Ralf,

I have many customers and I haven't heard to anyone having problems. However I observe most users have one session open, most user don't think about a second session. For myself I regularly have multiple sessions open and I don't find it an issue. Normally the global variables are around years, versions, cost centres and it is convenient the second session uses the same settings. I suggest user training unless there is a specific use case where report variables may be more appropriate.

Hello Ralf,

We are facing the same issue, and we don't have a solution as yet. I raised a support incident on this, but the problem is that global variables are user specific, so when you change them, they are changed for all open sessions. This indeed can cause quite quickly confusions on the other sessions, which might change context in an unexpected way.

I understood this problem goes away in V12, where global variables will also be session specific, and will enable the users to run the different sessions independently.

In the meantime, let me know if you figure out a workaround.

Best regards, Zsolt

Hi,

Using a control cube would only be a workaround to prevent opening the same report twice. But as I cannot control the closing of a report, probably in won't help. Besides it is a lot of effort to create such actions in each of the hundreds of reports. Should be something on session level at one central point of the application.

What I was looking for is a session control on process level, meaning: at time of login the platform determines that this user already has a running session and won't allow a second one. I think in SAP there is such kind of session or license control. Even better: Let the number of parallel sessions be configureable on user level, so power user A is allowed to hold up to five parallel sessions, whereas user B is only allowed to hold 2 sessions and all others only one.

However, I understand that this is not available now, nor in V11 nor in V12, too bad. (Thinking back to good old Sentinel License Manager in DW 5.2..:-))

Good to hear that global variables in V12 are no longer in the user context but in session context. However, I haven't found anything about this in the documentation. Can anybody from Infor please confirm this?

And finally to Peter's suggestion of a user training: I totally agree, this was adressed to the users several times and repeated from time to time, but in Germany we have a saying "Your word in God's ear"... so nobody cares about it.

Thanks to all contributions

Ralf
