What exactly is regarded as a "concurrent" session?

In Xpert.ivy a session is a http or ulc session. This means that every time a user starts a new web browser a new session is created.

However since Xpert.ivy 4.3 the counting of the concurrent sessions for licensing has changed. It is more likely to be concurrent users instead of concurrent sessions now.

In details:

• All sessions in which the same user is logged in are counted as one concurrent session as long as there are less than 10 open sessions for a user. In case there are 11 open session it is counted as 2 concurrent sessions. 12->3, 13->4, etc.
• Sessions in which no user is logged in (anonymous sessions) are also counted as above.

Consequences:

• If you exceed the concurrent sessions of your license a licence warning is reported.
• If you exceed it by more than 50% no new sessions can be created and a licence error is reported.

Regarding Named Users:

• Engine Admin User do NOT count as Named Users.
• The three Portal default users (admin, guest, demo) do count as Named Users.

The easiest way to check how many Named Users or how many Concurrent Users are currently defined or logged in is to use Java VisualVM (comes with every JDK, to be found in %JDK_HOME%/bin). You need to install the Axon.ivy Engine Monitor Plugin, to be found in %ENGINE_HOME%/misc/visualvm/visualvm-plugin.nbm.

Then open the running Ivy Engine in Java VisualVM, go to the tab Axon.ivy und look under License. Unless you have an unlimited Named Users and Concurrent Users license, the tab should look like this:
