  • 1.  Web console access breaks every time I try to undeploy a component - iMC 7.2 (E403P10)

    Posted Mar 31, 2020 10:56 AM

    Hi,

     

    I have iMC 7.2 that I need to upgrade to 7.3 very soon, before doing that I am trying to trim the fat and remove uneeded components. We only use the main platform [iMC PLAT 7.2 (E0403P10)]  and the Network Traffic Analyzer [iMC NTA 7.2 (E0401P04)]. I would like to remove the  iMC QoSM 7.2 (E0403P03), iMC UAM 7.2 (E0411), and iMC WSM 7.2 (E0502P05). Every time I try to undeploy any of these componenets, either through batch undeploy or one at a time, the access to the platform breaks and I have to restore from a snapshot because redploying does not fix it. Looking at the proccesses tab only three proccesses would be running, and the error I get when trying to access the web console is this:

    This is a rather general error msg, but I have seen it when iMC didn't completely shutdown. Try to first to [Stop] iMC, make sure all processes are gone and then do the Undeploy.
