How to divide equal load in Oracle Weblogic Cluster Node

Hello Friends..
I install Oracle weblogic 10.3.3.0 and oracle Forms [32 Bit] Version 11.1.1.3.0 (Production) on Two PC, PC-1 and PC-2.
I Create a cluster for load balancing and shifting the load from PC-1 to PC-2. Now I want to know which algorithm is best for equal load balance means i want to transfer equal load on both machine.
If PC-1 have 10 http request then next 10 request transfer to PC-2.
Please guide me.
Thanks,
Sachin

Hi Sachin
You need to have a load balancer or web server in front of your weblogic server cluster.
This is really a tunning excersise, so you need to try several options depending on the load of the enironment, however robin robin (default) should work for you.
You can see more details here:
Load Balancing in a Cluster

How to integrate Java SSO with Oracle Weblogic

Hi,
I am new to Oracle weblogic, but i want to do something like below.
I want to use Oracle weblogic as application server and want to integrate Java SSO into it. I think we can do it using Oracle access manager but since OAM itself is massive drop this plan.
I think we can use OC4j Java SSO into Oracle weblogic, but don't knw whether it is feasible.
Can somebody please guide me solve this problem.
Any suggestion or comment is most appreciated.

How to set autocommit false in Oracle Weblogic console?

Hi All,
While invoking the oracle Ebiz custom package from Oracle SOA 11g BPEL we are getting below error:-
java.sql.SQLSyntaxErrorException: ORA-02089: COMMIT is not allowed in a subordinate session.
Wondering if there is some properties through which we can set the autocommit false on the Oracle Weblogic Console.
Highly appreciate any pointers for the same.
Thanks in advance.

Yes I did set global transaction (XA) up in the db adapter. True, there are couple of commits in the API and from outside BPEL that works fine, the error i am getting when trying to access the API through BPEL. I am calling this only API from the BPEL.
Do you think there needs to setup explicit "autoCommit=false" somewhere in the weblogic console?

IIS 6 fails to load balance to weblogic cluster

Hi,
We have iis 6 which proxies request to weblogic cluster running on version 9.2 MP1. Recently we noticed the connections are overloaded on a weblogic instance while the other instance had lower connections.
I suspect it to be the IIS load balancing to the single instance. Can anyone help please.
I traced the IIS logs and can see the citrix IP as destination since the user access the application thru citrix sessions.
Thanks,

How To Integrate BPEL Process Into Oracle Weblogic Portal 10.3

Hi All,
I have bpel process which which has db adapters and Human Work Flow. I need to integrate this bpel process [ created using Oracle SOA Suite 10131] with Oralce weblogic portal 10.3
Please let me know how to achieve this.
Thanks,
Irfan Khan

Hi All,
I tried to call my BPEL Process thru JSP.
This is how my JSP looks like:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ page import = "com.oracle.bpel.client.Locator" %>
<%@ page import = "com.oracle.bpel.client.NormalizedMessage" %>
<%@ page import = "com.oracle.bpel.client.dispatch.IDeliveryService" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>InvokeHelloBPELProcess</title>
</head>
<body>
<%
String name = request.getParameter("name");
if(name == null) name = "HelloBPEL";
String xml = "<name xmlns=\"http://xmlns.oracle.com\">"+name+"</name>";
// Connect to the default BPEL domain using Locator
// Please set the password (bpel is initial password)
Locator locator = new Locator( "default", "welcome1" );
IDeliveryService deliveryService =
(IDeliveryService)locator.lookupService
(IDeliveryService.SERVICE_NAME);
//Construct the normalized messaged and send it to the oracle BPEL PM
NormalizedMessage nm = new NormalizedMessage();
System.out.println(" -=-=-=-=-=-=-= XML: "+ xml);
//attach the payload to the NormalizedMessage
nm.addPart("payload", xml);
//Post the message to the HelloBPEL process
deliveryService.post("HelloBPEL", "initiate", nm);
out.println("The BPEL process HelloBPEL initiated!!!");
%>
</body>
</html>
Now once i invoke this JSP page I am getting the 500 internal server error.
The error message is :
java.lang.Exception: Failed to create "ejb/collaxa/system/DeliveryBean" bean; exception reported is: "javax.naming.NameNotFoundException: While trying to lookup 'ejb.collaxa.system/DeliveryBean' didn't find subcontext 'collaxa'. Resolved 'ejb'; remaining name 'collaxa/system/DeliveryBean'
Here I have some doubts:
1) If xml payload that I am passing is correct?
2) In Locator, do I need to pass 'domain' along with 'password' as my password or it will always be "bpel". i.e.,
a) Locator locator = new Locator( "default", <password> );
OR
b) Locator locator = new Locator( "default", "bpel" );
Please let me know how to solve this error. I doubt that my xml payload constructed is wrong. could you tell me what is the correct xml payload for below BPEL process WSDL file:

Behavior of load balancers - Oracle weblogic 10.0 - immediate help required

Hi,
We have an environment where we have two load balancing servers for one application. We are facing an issue, where a request which comes from the front end (Ajax request) is re-submitted exactly after 3 minutes in this load balancing environment. At any time, one server is taking the requests, but the request is getting re-submitted after every 3 mins. First time, the request is taking more than 3 minutes to give the response, so, many requests are getting submitted each after 3 minutes. Can any one suggest me which setting/parameter of the load balancer cause this? And how to resolve this? We came to know that this is purely of load-balancing issue, as the same issue is not reproducible in normal environments (single server env)
Awaiting your immediate response,
Thanks in advance...
Gayathri.
Edited by: 900817 on Dec 29, 2011 9:34 PM

If I understand your scenario,
* a client at some other layer of your application submits an AJAX type request towards a service running on WebLogic 10.x
* that transaction IS expected to have a long execution time -- longer than 3 minutes
* your service on WebLogic is seeing the request submitted a second time (in error) after 3 minutes elapse while the prior thread is still running
It sounds like:
* the request was implemented as a synchronous call
* your AJAX framework is using a default TCP timeout of 180 seconds (3 minutes) -- pretty standard setting
* the client isn't seeing a response in 180 seconds and its TCP layer is assuming something errored out and is aborting the first TCP connection and resubmitting it.
Assuming the load balancer isn't implementing its own 180 second limit on connections without any traffic flowing, you may need to either
* find a way to tune your AJAX client to configure it to wait longer for responses
* alter the implementation of the service to be an asynchronous call so the AJAX client waits for a callback sent by your service when execution completes.
Hope that helps.

How to divide and load parts of Large Adobe AIR app for Android

Hi!
I want to create an app for Android but it will quite large. It will be larger than the 50MB offered by Google Play Store. This means that I need to find a way and break the app and load parts of it when I need them. Imagine it like minigames inside a bigger app.
It is not clear to me how to achieve this since every time on AIR, I can export and APK file for a mini-game let's say. Can I later download APKs and integrate them into my main app? How would this be possible? Another question that I have is: In order for a SWF to play on my app, it needs to be built by AIR for Android?
The best case would be to download content from In-App purchases and integrate in my app.
But these things are not so clear.
Thanks in advance for your help and support.

I don't know how your application is structured, but if you can split sections off into separate SWFs(plain AS3 document) then you could host those section SWFs online and require the user to download them on first run.
You could use the FileReference object to download the SWFs, save them to the File.applicationStorageDirectory, and then display/load them up with the Loader object when needed from the app storage directory. You would possibly need to check to see if the files are present at every boot of the app though as a user could "Clear Data" or "Clear Cache" of the app in the Settings of their device and one or both of those could/would delete the downloaded files.

How do you configure ORDS in a Weblogic Cluster? Getting "This installation has not yet been configured" on second server...

We currently have ORDS 2.0.9 installed on WLS 10.3.6 running on Windows 2008R2 behind an F5 load balancer. When the load balancer sends the connections to the server we configured first, everything works fine. When the load balancer sends the connections to the scaled out server, we get the ORDS page with "This installation has not yet been configured". The defaults.xml and related directories got created on the second server automatically. We tried changing the debug.debugger and debug.printDebugToScreen entries in the defaults.xml of the second server, but nothing happened. What are we missing? How do we configure the second server?

The issue has been resolved. After looking at the directories and defaults.xml that WLS created on the scaled out server, we figured that the configuration files were not created/copied from the original server. We ran the configuration from "java -jar ords.war setup" on the second server, restarted the application from WLS and everything started working as expected.

How to deploy WebLogic Cluster on a Blade?

Hi, I am looking for recommendations on how ( if it makes sense ) to deploy WebLogic
Cluster on the (Intel) Blade HW. The question is, actually, caused by the fact
that the Blade is totally redundant and load-balanced HW where the requests are
managed by a Big-IP module ( and redirected to the IPs on the internal Blade Cassettes
One of possible solutions, we discuss now, is "either-or", i.e. let's discard
the App.Server cluster and use the HW cluster. This might work for the request
load balance but we loose all other, out-of-the-box, cluster features like session,
EJB, JNDI and so on failover and balance features.
Any notes with this regard will be greatly appreciated.
Thanks, - Michael
P.S. I repeated the same question om "cluster" Newsgroup but have not seen any
responds so far.

It sounds like you're getting request routing and fail-over in front of
WLS with the Big-IP. Typically people would enable WLS clustering to
get replicated HTTP sessions in an environment like this.

Load balancing for BPEL Cluster

Can anybody tell how to configure the load balancer in BPEL Cluster ..? I am not able to get the correct documents for that. I want the request from the client can be redirect to any of the cluster server that will be having the PPEL Process deployed.
Can i use third party load balancer also or can i use oracle http server as load balancer ....how to configure in both the case?

Hi Dominik.
Thanks for responding to my message.
Where could i find more info relating to the WEB dispatcher.
I also posted a message on OSS and SAP did not mention
a WEB Dispatcher. (Startup Framework and the J2ee dispatcher handing the load balancing)
Is the WEB dispatcher a must or are there alternate solutions. I am still confused on this topic ??
On the current EP5 release, the load balancing is handled
via MS Load Balancing.
Thanks and appreciate the help !!

Admin Server Funcationality in a WebLogic Cluster

Is this a correct statement of how the Admin Server is handled in WebLogic Cluster:
"If you have a two node WebLogic 10.3 Cluster then you will have the Admin Server for the domain running on node1. The managed server within the domain will run on both node1 and node2. The managed server services your application(s).
If node1 fails then the managed server running on node2 will continue to operate, thus meeting your high availability requirement.
If you need to administer your WebLogic installation you will first have to restore node1 to an operational state so that you can access the Admin Server."
Thank you

Answers :-
Q>"If you have a two node WebLogic 10.3 Cluster then you will have the Admin Server for the domain running on node1. The managed server within the domain will run on both node1 and node2. The managed server services your application(s).
A>Admin server can be running on any node(Physical machine). One Managed server(say MS1) can run only on one node. Two nodes can host two different managed servers. Yes, managed servers services your applications.
Q>If node1 fails then the managed server running on node2 will continue to operate, thus meeting your high availability requirement.
A> Yes, that is the reason of using clustering : Load balancing and failover.
Q>If you need to administer your WebLogic installation you will first have to restore node1 to an operational state so that you can access the Admin Server."
Yes, if admin server was running on node1, then it needs to be up and running to administer the domain.
