We’re observing a potential issue with mac address retrieval on Windows machines, especially those with custom VMs installed that creates various virtual extra mac addresses. In the main test case, Vantage spent more than 10 seconds querying the list of mac addresses.
As an experimental workaround (that could cause less mac addresses to be seen – be warned for licensing purposes), one could add a
-J-Dims.suppress.native.macaddresses=true
or
-J-Dims.suppress.java.macaddresses=true
to your ims_<app>.conf file in C:\IMS\ims_<app>\etc\ims_<app>.conf . Importantly, only turn off one of the types of mac address checking – otherwise your licenses cannot be validated. The aim of this experiment is to determine which type of checking is more efficient. Additionally, an internal caching layer for mac address retrieval has been added – the hope is that this could improve startup (and initial license check time) significantly.
This option is available for IMS Commons 3.10.19.4.51 and later.
