Hot execution of a startupclass???????

Question

Hi all ..
I have a java class registered using "weblogic.system.startupClass"
property in WL 5.1 which basically loads few tables from teh database
using two of the connection pools defined in teh same property file.
Now my problem is something like this ---
restarting the server is a major pain for me as i have arnd 100+ EJBS
and lotta other activities during startup.
when ever i have something inserted in that database i have to restart
the entire server which easily turns out to be more than 15 mins job.
To avoid this i would like to have some event which would tell me
weblogic server to reexecute that particular startupclass.
and i dont have slightest of idea how to do it . any help in this
regard would save me loads of mytime.
something like hot deployment .......... ???
thanking u all in advance

Answer 1

Remember, a weblogic startup class is just a Java class that gets
instantiated by WLS on startup and has a couple of methods invoked on the
instance. Why not simply do something like this (this is intended as an
example only)?
import weblogic.rmi.*;
public interface DbCacheManager extends Remote
public void reloadCache() throws RemoteException;
++++ end of file ++++
import weblogic.rmi.*;
public class MyStartupClass implements T3StartupDef, DbCacheManager
public void setServices(T3ServicesDef services) { }
public String startup(String name, Hashtable args) throws Exception
reloadCache();
InitialContext ctx = new InitialContext();
ctx.bind("MyDbCacheManager", this);
public void reloadCache() throws RemoteException
// do whatever was being done by the startup class
Now, you can write a client utility that looks up the DbCacheManager from
JNDI and invokes reloadCache()...
Hope this helps,
