When a node for some reason is set to disabled status (the command 'tibcohost describeNodes -nodeName DevNode' returns node start mode as 'disabled'), one of the following two solutions can be folowed tto change it back to enable/automatic state.

Solution 1:
------------
You can use Tibco host CLI to change node status. Go to &ltconfig_home>/tibcohost/&lthostname>/host/bin and run the command-

tibcohost setNodeStartMode -nodeName DevNode -startMode auto


Solution 2:
------------

1).  Log into AMX Admin GUI --> Infrastructure --> Nodes .

2).  Select your node from list.

3). The node startup mode will be still show ‘Automatic’ ( Default ) in AMX Admin - where in this case it should have shown ‘Disabled’ .

4). Change it to 'Manual' .. hit 'Save' .. and hit 'Install' .

5).  Refresh the page – the synchronization state should go to ‘In Sync’ .

6).  Change it back to ‘Automatic’ – again hit ‘Save’ and then ‘Install’ --> Refresh.

Now your node status should be ‘Automatic’ and admin should be able to start node fine. If you see the node getting stuck in "starting" runtime state,  restart the tibcohost hosting that node.
