RE: Job Scheduler pattern

2002-01-25 Thread Paul Knepper


Joseph,

Very cool.  How do you stop a client-module that auto-started and then
restart it?  

Say you deployed the app (which also has ejb and web modules) and later
wanted to add another task to the scheduler.  Can you start and stop the
java client module, so that it would reload the properties file, without
affecting the web module?  I might have users logged in to the website and I
wouldn't want to redeploy everthing and messup any current sessions.

Thanks,
Paul

 I'd like to implement a job scheduler in J2EE. This would shcedule the

 Is it as simple as using the Timer and TimerTask in java.util to implement

 Does it matter as far as Orion goes whether I use a java.util.Timer as a

PMTo: Orion-InterestSubject: RE:
Clustering..
Clustering in orion is only for sessions. EJB clustering
is not yet provided.
The clustering mechanism in orion is based on
JMS(Topic/Subscriber). When every you keep information in session by
using setSessionAttribute(String name, Object object) the session information
is copied to all other clusters.
All objects in the seesion must be serializable inorder to
provide clustering. Once clustering is enabled if switch requests
between islands you will have session information valid.
Unfortuantely this mechanism is little expensive in terms of
memory since session information is kept in memory of all islands. So
adding one more machine or island into the cluster group doesn't reduce your
memory requirements rather it increase your memory requirements.
This mechanism have one drawback: If you keep an object
in session and later some place you get the reference of the object and modify
the object the modifications won't get reflect across islands:
Example:
UserInfo info = new UserInfo() // Some kind of
object... info.user_name = "oldName";
session.setAttribute("UserInfo", info) // At this point the info is
replicated to all cluster islands
//Later at any place of your code
UserInfo info =
session.getAttribute("UserInfo");
info.user_name =
"newName"; //This change won't replicated
//In some other program
UserInfo info =
session.getAttribute("UserInfo");
System.out.println(info.user_name) // If the request comes to the
same cluster where the modification occures you will get the "NewName" if the
request goes to another cluster you will get "oldname"
Work Around: If you do any kind of modifications to your
session objects put the objects again into session using
setSessionAttribute. Keep one thing in mind that when ever you call this
setSessionAttribute method the session info is going to replicate across
different islands.
I think this is too much to put down. If some one finds
boaring just ignore this mail.
This is the same problem which I faced and lead me to write my
own session management.

Hi all,
I know how to cluster Orion..after all, its pretty easy. What
I want to know from someone who knows..is if in the
1.5.2 version all the bugs (if there were actually
any) are worked out. Does Orion cluster with no problems? Does
session fail-over and application context fail-over work
without a hitch (providing all objects in the session
and/or context are serializable)? If you have two
machines in an island, and the session begins on one..does it automatically "copy" any session info to the other box for you? If you
shut that box off, and all requests go to the 2nd box,
does the session still exist with all objects still in
memory?
I take it each and every request on a clustered box requires
the session to be duplicated exactly as is to the
other machine? If this is the case, at what "rate"
does Orion copy out the session and anything else to another server in the island (or to each and every server in the island)? How
does this affect performance as compared to using just
a single box without clustering..is it 2 to 3 times
slower because of not only copying its session to one
or more boxes, but also having to deal with "merging" other boxes context/session information into its own? Or does a cluster
simply create the objects and session stuff on each
box as its generated (thus..its not some background
thread that copies session info when it has time to other boxes)?
Is it equally good at clustering on the EJB tier (so
scalability on the EJB tier or the front-end WEB tier
is equally as easy)?
Thanks.

Hi all,

This is an old question..I have asked it before. But the last few times I
saw this on the list, the products recommended to me didn't work well. I
forget which one, but one did work..partly. The service started fine, but
when you tried to shut it down, it would just hang. I also know of the
log-off problem and this one worked. What I am asking now..especially
since Oracle OC4J is basically Orion, is there a DEFINITE solution to
running Orion (and java for that matter) as a service that WORKS on WinNT
and Win2K (pro and server)?

Another thing..why does Orion not have its own service capability? I know it
needs to run on many platforms, but I would think it possible to create a
subfolder in the distribution for windows, linux, etc (or..even better to
keep the main distribution small, a separate add-on service
installer/deinstaller).

So, if someone could hook me up with a good link or two to service runners
that actually work with Win2K, and can run java programs, that would be
great. Ideally I would like the ability to see the output window show up in
a given Terminal session incase I have to Terminal in to a Win2K Server box
and start, stop or restart the service. But this is not mandatory.

   orion users,
  
   I've been using the test certificate from Thawte, as both the orion docs.
   and the OrionSupport suggested. That has been working fine. However, I am
   now ready to move to production with our e-commerce system and I have run
   into some major snags that leads me to think NO one is using Orion in a
   production SSL environment.
  
   After going through the Thawte process for getting a server cert, the
  'pick
   your web server' does not list Orion. After talking with Thawte support
  they
   suggested picking 'Apache SSL' as a choice. Ok, that seems fine to me.
   However, they also said I would need to pick the certificate type: x509v3.
  
   Since I've been using the 'SSL Chained CA Cert' for development, I wanted
  to
   try this out with a development cert to be sure it would work. I tried
  this
   using a X509v3 development cert but it will not work. Again, after getting
   back in touch with Thawte support regarding X509v3 not working, I said I
   will need to just use the 'SSL Chained CA Cert'.  They then informed me
  that
   they no longer sell this type of certificate, and that I must go to
  Verisign
   to obtain this type of certificate. Well, my first question to Thawte was
   'If you dont sell this type of certificate, why is it available on your
   developers cert pages?' Answer from Thawte: 'Yeah, I've been meaning to
  talk
   to our developers to take that off the website.'.
  
   Guess how much hair I've lost so far!?  Now I am in the 'process' of
  getting
   a certificate from Verisign. Of course they do not have 'Orion Server'
   listed in their pick list of valid webservers. Since I just started this
   process today I really dont know if they can/cannot support the type of
  SSL
   certificate I will need to work with Orion.
  
   I'll be the first to admit I'm not real familiar with the Java 1.3
  keytool,
   and different certificate meanings. But, if anyone has really obtained a
   valid production level SSL certificate, from any Certificate Authority,
  and
   successfully integrated this with Orion, please let me/us know how this
  was
   accomplished. The only docs I've see are related to development certs, and
   as I stated earlier, I've got this working fine. I now need to graduate to
   real e-commerce transactions. Please dont make me go back to Apache/JRun,
  I
   feel Orion is so much better but this is a real show-stopper. I have
  looked
   through the orion mail archives and it seems all discussions are related
  to
   trying to get the developer certs to work, not production certs.

  Connection conn = ds.getConnection();
  
  This will get you a connection from the pool, and return it when you
close
  the connection.

  Subject: SQL Server DB Pooling
  
  
  Hello,
  I am interested in setting up database pooling using INet's Opta driver
for
  SQL server, but I am having trouble with the configuration.
  
  I can get the driver manager for single connections to work, but if I
try
  any of the pooled conections I am getting a Cast exception.
  
  Any help would be appreciated!  Thanks,
  Dan
  
  Here is my configuration:
  
  
  data-source
   class="com.evermind.sql.ConnectionDataSource"
   location="jdbc/MyCoreDS"
   pooled-location="jdbc/pooled/MypooledDS"
   xa-location="jdbc/xa/MyXADS"
   ejb-location="jdbc/MyDS"
   name="My data-source"
   url="jdbc:inetdae:SQLSERVERA:1433"
   connection-driver="com.inet.tds.TdsDriver"
   username="sa"
   password=""
  /
  
  Here is the code I am using to test this connection:
  
  
   PooledConnection pcon = null;
   Connection con = null;
   int i=0;
  
   System.out.println("Starting");
   try {
  Context ctx = new InitialContext();
  
  /*
DataSource ds = (DataSource)ctx.lookup("jdbc/MyCoreDS");
con = ds.getConnection();
  */
  ConnectionPoolDataSource ds =
  (ConnectionPoolDataSource)ctx.lookup("jdbc/MyDS");
  pcon = ds.getPooledConnection();
  con = pcon.getConnection();
  
  Statement s = con.createStatement();
  ResultSet rs = s.executeQuery("select * from sysmessages");
  
  while (rs.next()) {
  %
  tr
   td%= i++ %/td
   td%= rs.getString(4) %/td
  /tr
  %
  }
  
  rs.close();
  s.close();
   }
  
   catch (NamingException e)
  
   System.out.println(e.toString());
   }
   catch (SQLException e) {
   System.out.println(e.toString());
   }
   finally
  
   if (pcon != null)
   try {
   pcon.close();
   }
   catch(Exception e) {
   System.out.println(e.toString());
   }
   }

EJB stub classes and stand-alone remote java client

2000-08-22 Thread Paul Knepper






I've been 
trying to get my standalone java client to access EJBs on a remote machine, but 
with no luck.I've deployed a J2EE 
application with my EJBs in it. But I can't figure out how to generate the 
stub classes.

I can't find 
the Orion tool to generate the stub classes that the client would normally 
reference from the CLASSPATH(as described in "Java 2 Enterprise 
Edition Developer's Guide" page 95). 
How do you generate the stub 
classes that enable the client to communicate with the enterprise bean? 
This is a simple thing to do with the deploytool that comes with Sun's J2EE 
Reference Implementation.During 
deployment you simply select a checkbox labelled "Return client Jar" when 
you deploy the application.

I don't 
understand how the client can resolve the EJB classes if you don't have the 
client stubs to include in your CLASSPATH. 
I keep getting a 
java.lang.ClassNotFoundExceptionexception. 

Also, what else do I need to deploy to my client 
machine, just orion.jar?


Thanks,
Paul
