I'm getting an ElevateDB Error #504 The maximum number of concurrent sessions (2) has been reached when I run my application from within the IDE.

Is this because I have ElevateDB Manager open and connected to MyDBSession and my application is also trying to connect to the same MyDBSession?

That depends on wether you're running a trial version or not. If so it right if not there's a problem. The most likely in the latter case is an old trial version hanging around. Uninstall, zap any elevate bpls and reinstall.

Roy, it is not the trial version, It is the fully paid for standard version. I have totally uninstalled the trial version.

I read a previous post regarding the 504 error, I think by Tim, that mentions the EDManager uses two hidden sessions to keep track of internal stuff. That leaves three sessions available. If I connect to another session called  MyDBSession inside EDBManager that is three sessions. There should be two more concurrent sessions available for use.

So If I have my IDE running and it has an Active connecttion to the same MyDBSession That's a total of four concurrent sessions. However, when I run my application from within the IDE It won't let me because it says I have used up all availabe sessions even though there are only 4 sessions in use.

If I then go back to the EDManager and close the MyDBSession and then run my application from the IDE it works.

I was asking for clarification as to why I'm getting the error message.

Because the 540 error message references (2) I'm thinking it's counting the EDManager session as one, the Active IDE sessiona as two and then from inside the IDE when I run the application as three.

If that's not it the only other thing I can suggest before I totally disappear under the water is threads. Beyond that its over to Tim.

Neither do I

Go to the on-line forums http://www.elevatesoft.com/forums?category=edb in the search field type 504 and (for me) it was the last entry on the first page.

If you're using local sessions only, check your TEDBEngine component in your
application, and make sure that it has its LicensedSessions property is set
to 4096:

http://www.elevatesoft.com/manual?action=viewprop&id=edb2&product=d&version=7&comp=TEDBEngine&prop=LicensedSessions

If you can't change the value to 4096, then the problem is that you still
have the trial version design-time package installed into the IDE.

I tried to change it from 2 to 4096 but it won't accept that value. It
reverts back to 2. (Yes, I did set the Active property to false first)

So, how do I uninstall the trial version design-time package and get
the real version installed?

I did goto the Add/Remove Programs section an uninstall the trial
version before I installed the new version. If I need to do something
else please let me know.  Thank you.

Things sometimes get left around so:

1. Uninstall the full version using Add/Remove Programs
2. Search for and delete any edb*.bpl file
3. Belt and braces - delete the install directory
4. Reinstall

That "should" sort it.

Michael,

Just uninstalling from the Control Panel will do it, but if you left the
Delphi IDE open, then the uninstall may not have been able to delete the
design-time BPL file, so it may still be loaded.  If you go into
Component/Install Packages, you will see the design-time package listed
under Design Packages.  Click on the EDB design-time package for the trial
version (you can tell by the path at the bottom of the list), and then click
on Remove.  Then, if the full standard version's design-time package is also
listed, you can just click on its check box to enable it.
