Loadbalancing Weblogic Managed servers using Loadmaster-KEMP

 

 Loadbalancing Weblogic Managed servers using Loadmaster-KEMP

One of the problems I encountered while testing weblogic cluster was not the weblogic cluster setup but getting a LB to test it. This was super easy with free LB from https://freeloadbalancer.com/


Weblogic Cluster is configured on the same server with two managed servers running on different ports. Application can be accessed with individual ports but to balance the load and access the application with single URL we need LB. Below we will see how it can be done

Oracle apex(ORDS) has been deployed on these two managed servers 

 

Once Weblogic manged server is configured properly  and application deployment is done. We can do the necessary setup at LB

 

Set up load balancing with Kemp


It's super easy to setup KEMP load-balancer with a virtualbox appliance.  Just download the vm image for virtualbox from https://kemptechnologies.com/free-vlm-download and follow the installation guide that comes with the download

  

Create a Virtual IP address to access the weblogic deployed application, in this case oracle Apex

 

 

 

User will access the page with http://192.168.43.60:80 and LB will direct traffic either to 192.168.43.95:7010 or 192.168.43.95:7020

 

 

 

 

 

 

 

 

Add real servers

Make sure “TCP Connection Only”

 

 

 

 

Server Ip or host name can be give, if host name is given make sure it can be resolved

 

 add mange server listening on port 7010

 

 Both managed servers are running on same machine with diff ports

 

 add managed server listening on port 7020

 

 

 

Let's check the status of these servers

Both managed servers are down now 

 

 

 

Start the Weblogic managed servers

 

 

Now the real servers status changed to “UP”


 

 

Let's access the application using virtual IP configured on KEMP Loadmaster

http://192.168.43.60/apex/apex_admin



 Test accessing the page with different scenarios like Acess the application when only managed server 1 is up, only when the managed er 2 is up, etc

APP-FND-01436: List of Values cannot find any values for you to choose error from concurrent request program parameter (R12 12.1.3)

APP-FND-01436: List of Values cannot find any values for you to choose error from concurrent request program parameter After upgrading oracle application 11i(11.5.10.2) to R12(12.1.3) running concurrent program request caused this issue When concurrent program is run for a concurrent request after upgrading to R12 12.1.3 the lov, which is attached to a parameter, gives APP-FND-01436: “List of Values cannot find any values for you to choose”. When the same request is run from oracle applications 11i 11.5.10.2 the same value set is working fine. The value set is based on a table. If you go and test the value set query from the value set definition screen it returns complete successful message yet if you go to the parameter of the concurrent request program form where the particular value set is used it gives you the above error. After searching google and oracle support I found metalink note 1400963.1, EBS R12.1: Parameter for Concurrent Request Using Table Based LOV G
