I am getting confused these days some times assuming by hostnames(VIP name) some times by conetxt root, now i am thinking we use both .. bye1 depending on requirement EG: apps.americaa.com/items/firstpage.jsp ani undi..

micxas Posted September 10, 2014 Author Report Posted September 10, 2014 Nuvvu question inkosari sakkaga ardham ayyettatu chebthey poyyi DevOps team ollani adigi osthaa For suppose I have a web application items which is running on a middleware product ( assume websphere)... web app(Item) context root is items. App name : items conetxt root:items Middleware servers this app resides on : prdws12, prdws14 so if i want to access this app we can use ..... http:prdws12/items/* ... which will be the application URL for enduser( assuming port 80, 443 are opened for external use). But instead in general we use a common name called VIP to access the application ( to hide the backendservers names for security, load balancing) now i create a DNS entry(IP address) with a VIP(host name) for example apps.enterprise.com... Now if end user wants to access the web application, what he does ? he enters apps.enterprise.com/items/ which will be routing the traffic to backend middleware servers, To acheive this we need to perform some load balancing at network level.. So my question is how this happens ( using a rule by redirecting all apps.enterprise.com to backend servers or by using both apps.enterprise.com and conetxt root(items) or it depends ?? Hoping this helps .. bye1

Check if you have any irule or packet header modifications etc ex: vuu... Do we really add conetxt roots at NLB level ? Eg: <VIP-name>/<CTXroot> ll go to these list of nodes/ back end servers ... or its purely done at VIP(hostname) level... like this VIP name requests all go to this list of servers...
