This problem happend with me after host with ADDM was unexpectedly. After startup system can not load tomcat end stucks on it like:

Starting local Tideway application services
    Starting Security service:                             [  OK  ]
    Starting Model service:                                [  OK  ]
    Starting Vault service:                                [  OK  ]
    Starting Discovery service:                            [  OK  ]
    Starting Mainframe Provider service:                   [  OK  ]
    Starting Phurnace Integration service:                 [  OK  ]
    Starting SQL Provider service:                         [  OK  ]
    Starting vSphere Proxy service:                        [  OK  ]
    Starting CMDB Sync (Exporter) service:                 [  OK  ]
    Starting CMDB Sync (Transformer) service:              [  OK  ]
    Starting Reasoning service:                            [  OK  ]
    Starting Tomcat:

For now I am not sure where problem is and how to catch it, logs does not say anything, or maybe I still not found THAT log. So, the fastest way to get ADDM to work: Load in your appliance from livecd To to init.d and move file tideway.sh in any safety place Load into ADDM host without starting tideway services Then move previously copied tideway.sh to it's own place and run:

 /etc/init.d/tideway {start|stop|status|restart|reload|condrestart|condstart|help}

You probably can see that tomcat does not start still, but now you can cancel it and after run:

Starting local Tideway application services
 Starting Tomcat: 
[root@addm opt]# /etc/init.d/tideway condstart

This will try to start all services which not started yet, and may start tomcat also. This guide does not fix the problem, in the next reboot or appliance restart this shitty tomcal will freeze again, twis guide is just to force run ADDM.   UPD: Just like this magic looks:

[root@addm ~]# service tideway start

    Starting Security service:                             [  OK  ]

    Starting Vault service:                                [  OK  ]
    Starting Discovery service:                            [  OK  ]

    Starting Reasoning service:                            [  OK  ]
    Starting Tomcat: ^C
