Must supply a DBC file name

After re-applying TXK Rollup S for an issue with TNS described in a previous post, JSP ping test launched through System Administration responsibility failed with this message:

http://jupiter.justanexample.com/OA_HTML/jsp/fnd/fndping.jsp

Must supply a DBC file name.

$FND_SECURE pointed to $FND_TOP/secure. We had $CONTEXT_NAME.dbc, $TWO_TASK.dbc files in it. The aoljtest also has JSP ping. But those JSP ping gave the result "Test is no longer available".

If I create the URL manually and add the dbc clause:

http://jupiter.justanexample.com/OA_HTML/jsp/fnd/fndping.jsp?dbc=$CONTEXT_NAME.dbc

So now the question is, why is it not creating the URL correctly.

Node id does not exist for the current application server id.

I am doing sanity checks on an instance which has been converted to shared application file system.  The DBA was working on it till late night, so he is not available now.  I was unable to access the home page.  I saw some old Apache and Jserv process.  When I tried to stop apache, I got the following error:

$ adapcctl.sh stop

adapcctl.sh version 115.55

Node id does not exist for the current application server id.

Apache Web Server Listener is not running.

Node id does not exist for the current application server id.

Node id does not exist for the current application server id.

Apache Web Server Listener (PLSQL) is not running.

Node id does not exist for the current application server id.

A search on metalink yielded note 359998.1 which suggested a mismatch in fnd_nodes.server_id and APPLICATION_SERVER_ID variable in the dbc file.  Running adgendbc.sh was suggested as a solution.  So I manually ran $COMMON_TOP/admin/install/adgendbc.sh.  This recreated the dbc file.  After this I was able to successfully stop and restart Apache and get to the instance.
