Awhile back, I received a notification that I had to add this setting to my Pega 8.1 environments: -DNodeSettings="lac/traditionalLACRegisterSynch=true". This is a WebSphere JVM setting.Is this still needed for Pega 8.3 and beyond?Thanks!***Edited by Moderator Marissa to update platform capability tags**** Security System Administration ReplyI also have this Question (0) FacebookTwitterLinkedinEmail Copy Link Copied!
