Thanks for sharing knowledge, badass explanation.🤝

Thanks for the explanation, i have a couple of questions :
1. Does MS1 and MS2 need to have different names?
2 after unpacking to node 2, i run startweblogic on both nodes or just in node 1 and control everything from node 1?

1)in the process of upgradation if it is horizontal clustered installation first we will upgrade domain in one node after that we can copy entire domain to node 2 right ? if we copy like this how node 2 will be recognized that purticular domain ? after copying domain what is the process that weblogic admin need to do just i want know clearly please let me know it is very very usefull to me.

2)so if we copy domain to node2, initially it has existing domain as well right ? what about that domain should we delete or how it is please explain

[swamy]

If we have same domain in four nodes should we need to stop domain in four nodes or if we stop one node will it be populated to other nodes as well ?

[SwamyD-do]

if we want to do clustered domain upgrade first we have to upgrade in one node and copy the domain to node2, 3, 4.... right ? by using pack and unpack command it is only the fastest process right? and is it correct process ?

In the process of domain upgradation after copying domain from one node to anather node in which file we need to update ipadress of the node 2, let me know what are all the file we have to update after domain copying ?

[SwamyD-do]

Oracle_Home or middleware in this case these folders are just created by us right to install weblogic server inside this folder but not auto generated folders (in the sense if we install weblogic software wlserver folder is auto created)

[SwamyD-do]

So we have to do reconfig only one node after that we can copy domain to n number of nodes right ? so if we copy like that we can have two domain homes right ? can we delete this initial domain home? and if we install weblogic software can we get "Oracle_Home" or "wlserver" so we can have two oracle homes and two wlserver folders right ? can we delete old ones ? by using rm command ?

[SwamyD-do]

is jvm performance issue and application performance issue both are same ?

[SwamyD-do]

after upgrading java which file we need to update in weblogic side ?

[SwamyD-do]

if we have two node cluster in two nodes we have same domain which url we need to use node or node2 ?

[SwamyD-do]

If we have two node horizontal cluster domain will available in two nodes, so if we want to access the admin server url, which ip address ulr can we use either node1 or node2 ?

Sir one of the interviewers have asked me, if we copy domain from one node to anather node after copying what is the process ? is it ended with only copying the domain is that task finished ? this is the question which i have faced in the interview. please explain this sir

[SwamyD-do]

what is the difference between weblogic 11g and 12c "installation" ?

[swamy]

If we doing weblogic server migration to change ip address in all configuration files any single command is there in Linux or any other way is there ? Please let me know

[SwamyD-do]

sir what are stubs and heartbeats and what are their uses ?

Hi Sir, could you let me know how patching can be applied for Weblogic servers while on horizontal cluster, can we patch on one machine first, then patch cluster servers on second machine after a month? Or to be patched only on machine1 with Admin server or both machines to be patched at same time ?

[swamy]

If we copy domain one machine to anather machine we can have two domains right ? What about old domain what should we do to that?

How we can convert Managed Server running in single node to cluster configuration.

Hi Sir what is the difference between domain upgradation and domain migration ?
