AIMMS PRO 2.3 Release

AIMMS PRO 2.3 allows AIMMS WebUI apps to run on any node in a PRO cluster. Previously, the WebUI app would only run on the node on which it was published. Therefore we added the following features:

Publishing a WebUI application makes it available to all the nodes in a PRO cluster.

Additionally, running WebUI applications are now distributed evenly across all the nodes in the cluster (upon clicking Launch).

AIMMS PRO 2.3 allows the PRO administrator to understand how the cluster is configured and how the license profiles are used: the administrator has access to a set of monitoring pages. For more information, click here.

When upgrading from a previous version of PRO to 2.3, you should run the PRO configurator and start the PRO services from there.

If you want to use this version of PRO with WebUI apps, you should at least use AIMMS 4.6 for that. If you already have WebUI apps published with an earlier AIMMS version, please republish these with AIMMS 4.6.

Due to missing .dll’s, sometimes the services could not start.

Sometimes, a ‘data connection lost’ message was displayed when using WebUI apps.

There was a problem that would leave WebUI Data Sessions processes running upon stopping the service; upon stopping or restarting all active sessions are now killed.

The client licenses for WebUI sessions that are idle will be reclaimed after a configurable amount of time.

PRO 2.1

AIMMS PRO 2.1 Release

The AIMMS PRO 2.1 Release was released on March 30, 2015 (build 2.1.1.54).

The purpose of PRO 2.1 is to make the IT installation and roll-out to end-users easier. Therefore we added the following features:

In case you have setup AIMMS PRO to use Active Directory for user management, users no longer need to explicitly log into the PRO portal. When opening up the portal, users will automatically be routed to the overview of AIMMS apps assigned to them.

As browsers are dropping the plug-in support, we developed an ‘App Launcher’ as a replacement. Users only need to download and install this once.

To remove the need to open several firewalls ports to be able to run AIMMS apps over PRO, we have condensed all network traffic to one port. Using this feature requires AIMMS 4.4 or higher.

We now offer encrypted data transfer (SSL/https) for WebUI users.

Please note that when using WebUI with PRO 2.1 you do need AIMMS 4.4 or higher. Also, you need to republish all existing WebUI apps under PRO 2.1 to use AIMMS 4.4. You need to republish all existing PRO desktop apps if you want to benefit from the ‘one firewall port’ feature.
