There are multiple things we need to do when we use the Loadbalancer
1) Change the access url in the CMC:
Login to CMC- Applications-- Webservices properties
Change the Access url to the Loadbalancer url.
2) Running the WSDL Generator:
Once you migrate the QAAWS or Crate the QAAWS, execute the below url in all your 3 tomcat nodes individually by changing the host name.
http://<hostname>: <port>/dswsbobje/qaawsservices/wsdlGenerator
Here Hostname is the Server name where Web application Server is deployed.
This url will Regenerate all the WSDLs.
This (WSDL generator) simply creates qaawsWSDL.zip on the Tomcat by retrieving query information from CMS so you don't loose any query.
or
we can configure common shared location for qaawsWSDL.zip to avoid the WSDL generator activity.
