Weblogic RMI and Cluster

Hello,
We are deploying services that use legacy code via JNI. For safety, we want to
run these processes in separate JVMs and plan to have the application server(s)
access the code via RMI. To handle the system load we want to option to run multiple
instances (multiple JVMs) of these services.
WebLogic's rmi clustering support seems to be a good fit, but we are confused
on how to deploy the services.
In clustered environment when we run
java weblogic.rmic -clusterable classname
It created classnameRTD.xml file. Presumably this file needs to be put somewhere
to deploy the service? Where does it go? Do we have to do anything else to handle
the replica aware stubs and make them available to our client (in our case EJBs
running in the application server(s)?
Can we run replica aware stubs in a non-clustered application server? This would
allow us to have multiple instances of our service handle the load from a single
application server.
Thanks,
Tushar Shah

Problem with weblogic.deploy and cluster

 I'm having some problems with the weblogic.deploy class when trying to refresh
 a jsp file. Using the following command to redeploy the entire application works
 fine:
 java weblogic.deploy -port 9876 -host apptest01 update
 administrator portal c:\portal-site
 However using the following command to refresh just one jsp
 file:
 java weblogic.deploy -url t3://apptest01:9876 -username system
 -jspRefreshFiles ./index.jsp -jspRefreshComponentName portal
 refresh administrator portal
 produces the following stack trace:

 Hi John,
 How's tricks?
 It looks to me as though the olbcluster JNDI reference isn't being resolved from
 the tree. A similar error results when a Connection Pool cannot be resolved, the
 JNDI context env.jdbc is resolved but the particlar pool isn't. In my experience
 it often turns out to be an error in the correlation between the deployment descriptors,
 settings applied via the console and references made in the code.
 That's my tuppence worth,
 James :-)

Weblogic.rmi and java.rmi

Hi,
I would like to use weblogic to access a java object on another machine that
is using java.rmi. I am using the java "rmiregistry" on the non weblogic box.>
How can I write a java program that maintains state to that object at weblogic
startup and call it with a weblogic client?
Thanks

Weblogic plugin and cluster concepts

Hi,
I would like to clearly understand how the plugin and cluster work together in achieving load balancing.
For example if Apache proxies the request to each server instance in a cluster(if we use weblogic cluster parameter) on the round robin basis. How does the cluster do the the load balancing and how does it respond to webserver. I have read some documentation in edocs but couldnt find anything that would clearly explain how this works. All it talks about is the configuration of plugin and load balancing techniques in the cluster.Please throw some light on this and help me figure out how this thing works.
Thankyou very much.

Hi Hoze,
In Oracle Enterprise Manager lingo, a plug-in simply enables EM to monitor heterogeneous environments. In some cases this capability is available OOB or after the fact.
The table here
http://www.oracle.com/technology/products/oem/extensions/index.html
makes it clear if a plug-in is available OOB or available for download.
Thanks

Urgent help: how to create data source for Weblogic RMI driver

Hi,
Please let me how to create data source for Weblogic RMI driver using Administrator
console.
I understand that the following steps are required:
1.Create connection pool for the RMI driver by specfiying URL as
jdbc:weblogic:rmi and Driver as weblogic.jdbc.rmi.Driver. Now
comes the problem.. what do put in properties text area? I am
talking about key/value pairs required?
2. Having done step 1 ( which I was not able to do) , create a new DataSource
mapping to the connection pool created from step 1.
How to accomplish step 1 ? I want to finally connect to Oracle
database. Please help me.
pradeep bhat

DataSource will internally do that for you (It will use RMI internaly) . You
dont have to worry about the details of using RMI driver. Thats what is a
DataSource is for.

Hi Sree,
What u have written is abt configuting Datasource for type 2 and
4 drivers.
But I want to know how to create data source for RMI driver. If
I map this datasource to connection pool that is created for
type 2 or 4 drivers, i don't understand why RMI drivers are
required in first place. If i do map the data source to connection pool
created
for type 2 or 4 drivers then where i
would not have used the URL as jdbc:weblogic:rmi and Driver as
weblogic.jdbc.rmi.Driver.
Hope u will help me.

Hi Pradeep
To create a connection pool you have to use a database driver not RMI
driver. So use a thin driver or the WebLogic jDriver for Oracle to setup
your connection pool. Once the connection pool is created you can create
a
DataSource and use this datasource to connect to the database.
The RMI driver can be used to get connections from the database via the
connection pool and in that case you dont need a datasource. Recommended
approach is to use a DataSource.

Weblogic.rmi.internal.BasicRemoteRef and ClusterableRemoteRef

Hi,
I have a ejb3 stateless session bean deployed on a wls 10 mp1 cluster (1 Admin + 2 Managed Servers).
The client side reference is a:
weblogic.rmi.internal.BasicRemoteRef when invocations go to Managed Server1
and
ClusterableRemoteRef when invocations go to Managed Server2
Is this indicative of a problem in cluster setup etc. ?
Thanx,

Hi ! I have a similar problem.
I have an EJB3 stateless bean on a WLS clustered server, in the same machine, server1 and sever2.This EJB3 is deployed in a application called appli.ear
My client is messageDrivenBean mdb deployed in another ear application client.ear , in the same machine, in the same clustered server.
Sometimes, my client call is succesfull, but most often, my lookup fails with java.lang.class.cast Exception.This exception is thrown because i get weblogic.rmi.internal.BasicRemoteRef class from my lookup.When my call is succeful ,i get weblogic.rmi.internal.CollocatedRemoteRef class.
Is it the same problem ? Must i get patch you are talking about?

Questions on Weblogic RMI

Hi
          I've a few questions on WL RMI that I couldn't figure out from the
          documentation.
          Suppose I have a cluster containing Weblogic servers server1 and server2.
          Server1 hosts an RMI object o1 that is bind to the cluster wide JNDI tree.
          O1 implements remote interface i1 that has a method m1 which takes as an
          argument an object o2 implementing remote interface i2. That is:
          public class o1 implements i1 {...}
          public interface i1 extends weblogic.rmi.Remote {
          public void m1 (i2 _o2);
          public class o2 implements i2 {...}
          public interface i2 extends weblogic.rmi.Remote {...}
          Now if inside server2 I create o2 using the default constructor, lookup a
          reference to o1 and call method m1, will o2 get passed by value or by
          reference? Is there any way to control this? What if I don't use the
          constructor to create the object but the object is hosted in server2 and I
          get a reference to the object using JNDI lookup? In short, how does WL RMI
          decide when to pass an object by reference and when by value.
          I'm trying to increase the scalability of a system by distributing its
          modules as RMI objects to several machines running Weblogic server, and I
          need to know the details on how WL RMI works. The documentation seems to be
          rather inadequate...
          Thanks for reading this far :)
          - Juha


Actually, O2 will always be passed by reference because it is an RMI object
          (i.e., it implements weblogic.rmi.Remote). If O2 were a non-RMI object, it would
          be passed by value if O1 is in a different process and by reference if O1 and O2
          are in the same process.

Error when running weblogic 10 in cluster

I am testing out weblogic 10 and when I run it with a single managed server and an admin server then everything works fine. When I run it in a cluster with a valid test cluster license, I get the following error. Does anyone know what the cause of this error is and how to fix it? Thanks for the help.

We solved this by increasing the number of open files, by adding the following in the /etc/security/limits.conf

WebLogic 11g and Spring beens injected into EJB

All,
I am getting an error injecting spring managed beans into EJB's within WebLogic 11g. I am using an interceptor extending the SpringBeanAutowiringInterceptor to set the context name by overriding the getBeanFactoryLocatorKey method. This is configured within the ejb-jar.xml file as an interceptor-binding for all ejb's. The beanRefContext.xml is in the root of the ejb jar and on the class path.
The application deploys however when I can the remote ejb interface the following error occurs. The remote interface and model passed on the method call are deployed within a ejb-client jar file that within both the ejb and web applications class path. The ejb and web app are deployed separately i.e. the web app is deployed as a war out with the ejb ear.
Does anyone have an idea on what is causing this? I suspect it is something to do with the class loaders / classpath and where the sping managed context is being loaded from. The Spring jars are deployed within the root of the ear and referenced within the Class-Path manifest.
Regards
Neil

After some tinkering with this I am now getting a different error. I believe the error has changed as I am now deploying Spring 2.5.3 with my EJB. Does anyone have an idea on what is causing this?
Note I have also deployed the code onto OC4J and it works fine.

Single Client Access Name for Weblogic Forms and Reports.

I have a 2 node clustered system:
Windows 2008 R2 64-bit
Weblogic 10.3.3 (on each node)
Weblogic Forms and Reports 11.1.1.3 (on each node)
Database 11gR2 RAC 11.2.0.1 (on each node)
The forms and reports are clustered and I can connect to each from each of the two servers and the cluster is working well.
The database uses Single Client Access Name (SCAN) to present the database as if it were one server called dbserver1.
I was wondering if there was a similar thing for Weblogic and what everyone else uses to present their application as a single name to the user.
I tried using Windows Network Load Balancing, but this stops the database scan listeners from working.
Thanks.

Dear,
Did you find an answer to your question back in 2009?
We are facing the same installation architecture, but we do not find any concrete information regarding SCAN with Oracle Forms 11g

Weblogic 9.2 cluster install across 2 linux servers - authentication errors

Hello all,
 I am currently trying to install a 9.2 cluster across two Linux machines, but am having a few problems that I was hoping someone here could help with. I?ve been reading the documentation, but feel as though it?s getting me nowhere.
 I have two servers, on which I have installed weblogic portal 9.2. On the first I have then used the configuration wizard to great an admin server and cluster members 1, 2 and 3.
 A cluster is created and the three cluster members are assigned to it.
 Then I configure two unix machines, for the servers 1 and 2.
 I assign the admin server and cluster member 1 to the first server. Cluster members 2 and 3 are assigned to the second server.
 The connection pools and JMS stores I left as the default values.
 The configuration completes and a domain is created on the first server.
 I have copied the complete user_projects directory to the second server. I didn?t want to go through the configuration steps on each server that weblogic was to be installed on, so this looked like the easiest way to get the startManagedWeblogic scripts onto the second server. Also I didn?t find anything in the documentation that mentioned how to set up a cluster across multiple machines in any detail, only how to install multiple instances on a single server and run them as a cluster.
 I manage to start the admin server ok and can connect through the web based admin console.
 The first cluster member also starts up on the first server.
 Now I go to the second server again, and when I try to start the cluster members here I get Authentication errors:
 <Jan 31, 2007 2:56:22 PM CET> <Error> <Security> <BEA-090854> <SAMLCredentialMapper provider initialization failed: Could not retrieve credentials for AssertionSigningKey.>

Hello ,
 I can help you in this regard, (let me see).
 Let me start from the beginning.
 Assumptions:
 M1 is hosting 1-Admin server(AdminServer), 2-Managed Server(ms1,ms2),
 M2 is hosting 1 -managed server (ms3)
 1. Install WebLogic Server/Portal product on M1 and M2 say /home/user1/bea1 - on M1
 /home/user1/bea1 - on M2
 2. Create Cluster Domain using ConfigWiz/WLST.
 [ here I will talk abt Config Wiz)
 - Open config Wiz
 - Create domain in Production Mode.(ideally Cluster is not supported in Dev mode )
 - Create 1 Admin server, 3 Managed server Host = <M1> and config SSL port
 AdminServer ? Host_M1
 Ms1 ? Host_M1
 Ms2 ? Host_M1
 Ms3 ? Host_M2
 NOTE: *** Don't use IP addresses - use hostnames. The hostnames need to be specified in the correct format. When specifying a hostname, use the receiving server side's rules for SSL certificate hostname format when specifying the server address. The address that a client uses needs to match up with the server's SSL certificate host identity field ((example: pint21.bea.com on both server/client side, not just pint21 and other pint21.bea.com)
 Using the 'keytool' Java utility, verify the content of hostname identity embedded in the demo SSL certificate
 $ keytool -list -v -alias demoidentity -keystore DemoIdentity.jks
 Owner: CN=pisol18, OU=FOR TESTING ONLY, O=MyOrganization, L=MyTown, ST=MyState, C=US
 - Config Data Source (conn pool) to Any DB Type you like, test them and run the DB scripts if applicable (Run DB).
 3. Create Managed Server template Using Pack/Unpack tool
 3.1 Using <WL_HOME>\common\bin\pack.cmd with ?managed option create managed server template.
 3.2 Using <WL_HOME>\common\bin\unpack.cmd on M2 to create the domain on Host2
 4. Starting the Admin Server
 5. Start the Managed server in many way. As given on edocs.
 http://edocs.bea.com/wls/docs92/ConsoleHelp/taskhelp/clusters/StartOrStopAServer.html
 I hope this helps you,
 Thanks

I have a question about weblogic RMI , how can I resolve it.Thank you

I have a question about the weblogic RMI .
I have a program.web services+weblogic RMI +Data Sources When I run the program in the console application.it is ok.But When i run it with the web services(it 'is mean Get some parameter and run the different program).it's fail.The Exception is
cannot assign instance of yype weblogic.rmi.RMIServices_1033_WLStub to field demo.RMIServer_1033_WLStub.stubinfo of type weblogic.rmi.internal.StubInfo in instance of demo.RMIEsrver_1033_WLStub
how to resolve .Thank you.

Hi Charles,
Parental Controls has always had problems with https sites, no idea if it's fixed in 10.9.x or not.
When you setup your Mac it shouldv'e made an admin account, are you not running from that account, or did you somehow change it to a Managed account???

Weblogic - Fusion Middleware Cluster - Clarification - 11g

Hello All,
I've checked the forum and would need just a little clarification regarding weblogic cluster & fusion Middleware + Load Balancing.
My current Setup is:
==============
1 APP Server: Runs Fusion Middleware 11g Forms and Reports + Weblogic + OHS (windows 2008R2)
1 DB Server: Standalone database 11gR2 installation (windows 2008R2)
I've been asked to add a new app server and setup load balancing between the two app servers in order to split the incoming forms & reports requests.
What do I do? Do I install the new app server like the first one and just add it to an existing domain(clustering)? Is there a difference between fusion middleware clustering and weblogic clustering (as in database RAC - the whole idea being failover 24/7 no single point of failure?)
I would appreciate any assistance, and need not great detail, just need to make sense of the whole thing.
I'm already on with the following document: [http://docs.oracle.com/cd/E21764_01/web.1111/e13709/toc.htm]
Thanks in advance
Jan S.

Hi Jan
You are almost there. I would like to clarify some points for you.
1. You already have WLS + Forms/Reports and of course Backend RCU Database that has all the meta data for Forms/Reports. This RCU database is on single server Oracle database.
I've been asked to add a new app server and setup load balancing between the two app servers in order to split the incoming forms & reports requests.
2. The first question for above requirement is, do you need the new Server on the same Existing physical box or a different remote physical box. If on the same physical box (which I doubt), then there is NO need to install any new software like WLS, Forms/Reports etc. All you do is create a new Managed Server and add it to your existing Domain. NOW, do you currently have a Clustered Domain. If you, all you do is add this new server to that cluster. If not, then you need to add a New cluster and add your old and this NEW managed server to that Cluster. If your existing domain is only single server and is very recent, I would prefer create a brand new Cluster domain with Different Port numbers (you can change port numbers anytime later also). Then add/create one or two managed servers.
3. If you are give a new physical box for this new managed server, then YES, you do need to install exactly SAME version of Weblogic Server and same version of Forms/Reports server on this new machine. Then create a Cluster Domain with 2 managed servers. One managed server on first box where you will have Admin Server + Managed Server 1. Then run pack command. Go to other machine. Run unpack command to create second Managed Server. Now you got 2 managed servers in a Single Clustered Domain.
4. Now comes the Load Balancing Part. Never ever expose the individual managed server host and port and WebApp urls for any Clustered Domain. Instead install Apache Http Web App Server which I guess is same as Oracle Http Server. Oracle renamed it (there is no need for this, but it may be company policy). Anyhow all you do is, just install Apache Web Server. Copy some .dll (.so on linux) files to this apache installation. Then update httpd.conf file or weblogic.conf file with details of clustered weblogic domain managed servers host, port, url patterns etc.
5. All the External Requests will now go to Apache Web Server like http://apachehost:apacheport/xxxUrl. This Apache will take care of LOAD Balancing, Failover etc and based on input url pattern will redirect requests to back end cluster of weblogic managed servers.
6. The backend RCU database that has Metadata for Forms/Reports NEED NOT be Clustered. If you really have extremely heavy data, then you can have Oracle RAC database. Have multiple DB Nodes in RAC. For each Node, create a DataSource in Weblogic conolse and finally one master Multi Data Soiurce that uses all these single Datasources. But very rarely you really need RAC or clustered database for RCU. So for now, just go with single non-clustered Database that has RCU Schemas.
In conclusion, even though you have Forms/Reports, just follow the standard normal Weblogic Clustered domain Architecture for your requirement. All clustering is at application server level and nothing to do with any Oracles softwares like SOA/BPM, Forms/Report, BI etc etc.
Thanks
