You might be better off asking this in the dedicated Weblogic area - http://www.experts-exchange.com/Web/Application_Servers/Weblogic/ - to find out what they mean by "application" and "admin" server.

They will probably be started by a script in one of the /etc/rc*  directories (Or it may just be a link to a script in /etc/init.d)
Those scripts can also be used to stop services - just run the with the syntax `scriptname stop`

Scripts in each of the rc* directories are run in (numeric) order as the system comes up thru the runlevels, i.e. /etc/rc1/S100, S101...S999,
then /etc/rc2/S100 and so on;  Once you've found the 2 relevant scripts, just use them in the reverse order in which they ran on startup to ensure they are stopped in the right order.

either weblogic comes with rc-script(s), simply check in /etc/init.d (for example try: grep -i weblogic /etc/init.d/* )
or weblogic is started by its own script  startWebLogic.sh
in the later case you have to kill the started processes yourself (either use
  ps -ef
or
  ps -ef|egrep -i 'weblogic|java|PID'

Hi Naveen,

Weblogic is a middleware , which acts as an interface between the Application server and the database server. This forms a three-tier environment. Thats why to stop the business, u must first stop the Application server, then the Weblogic server and then the database server.
Now the term servers is user for software engines...It doesnot means physically seperate servers.

It is possibe to have application and Middleware physically on the same SUN box and the database server on a diferent SUN box. or U can have all the three on 3 physically different boxes.... This helps in having a heterogenous environment. eg : Database running on Solaris...application running on say - NT / 2000 and weblogic running on AIX....this is very much possible...

Ur startup and shutdown scripts exists in /etc/init.d directory

Hpe this helps...

regards
Sandeep
