Thanks for sharing knowledge , badass explanation.🤝

Perfectly explained.. Thanks 😀

Thank you. Good information.

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. Yes 2. Yes, from node 1 because there is only one admin server each domain.

All managed servers are controlled from the admin console which use node manager.

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 ?

Upgrade has to be done on each node because upgrade update binaries. For current version you have to install binaries in new Oracle Home,. Then upgrade domain on primary node and then pack and unpack on all node

If you are upgrading weblogic server then it's not required.

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

You have to use pack and unpack command to move domain on each node after upgrading on primary node where you have admin server. Installation and domain should be on each machine in the cluster

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 ?

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

@digitak.middleware

create 2nd machine pointing to node 2, create 2nd managed server amd assign to 2nd machine, create cluster and add both managed servers, install weblogic on node 2 on same path, pack and unpack domain from node 1 to node2.

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 ?

We have to install weblogic on each host in the same path, and then the domain has to be copied on each host. That means we have to maintain Oracle and Domain home on each host

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 ?

@digitak.middleware

5 ай бұрын

You have to patch each node. To avoid downtime you can apply in rolling fashion one by one on each node. You can't have a gap of one month, you have to apply it at the same time otherwise your applications will not behave properly based on the fixes applied in the path.

Answer depend on multiple situations, what's the purpose of copying domain. If you copying using pack and unpack during horizontal clustering then nothing required. If you want to migrate domain on some other machine then you have replace i.p and hostname on each file inside domain with new host where you have copied the domain. If db host also changed then you have update jdbc XML files with new db host as well. further it depend on the domain configurations and the applications deployed.
