cannot open webpage after I delete the server id from the database.

[Jason Yu]

HI, All:

I was following this procedure to change my second development server's ID. 

Shut down the second dev instance

Run the following queries in its database:

delete from cluster_server_uptime;

delete from cluster_server_action;

delete from cluster_server;

Start the instance again

Request and apply a new license

However, after I finished this procedure, I found I am not able to open the frontend webapge at all although I can start the startup.sh script. 

I checked the dotcms log file and found the following error. Since I don't want to restore my database, is there other way I can restore the server?

The above procedure is provided by the dotcms support. He was helping me to resolve the push function between two servers, the second server was a clone of the first one.

If you remove the cluster information from the database I think you also need to remove the server_id.dat and/or license.dat from the dotsecure directory... Not 100% sure though, but that's what we do when we have a license issue and I see something regarding the license manager in the stacktrace.

Kind regards,

Xander
