If your database is supported on VMWare, yes.

But why do you do it this way? Since a database server needs much more resources I would do it vice-versa, database server on bare metal and all other instances (CI and DI) on VMWare...

Thank you Markus.We will take your suggestion in to consider.

We already have sap (CI+DB) on same server and now we want to move just the DB server on to vmware.

1. SAP Supports or we will have any issues having sap on 2 different environments like one is on physical & another on vmware ?

2. If supports,how we can go ahead moving DB on to vmware ?

a) install new DB with same DB hostname on vmware then copy the data files , point to CI

b/ fresh distributed install then copy the DB ?

How we can go for it.Anybody suggestions that would be really appreciate.

Thanks

No support issues as long as your database is supported under VMWare.

You can use both approaches - again depending on what database system you use.

I would always put the database server on bare metal.

We use MS SQL.

install new DB with same DB hostname on vmware then copy the data files , point to CI

What is the procedure to connect DB to CI

If we move datafiles to new server and install SQL Server...How can we connect to Central Instance on different host.What is the configuration file name ?

[former_member204746 · Accepted solution]

check SAP profiles in /usr/sap/SID/SYS/profile

it's the SAP system that connects to your database... not the other way around.

So, Do i have to do this ?

For moving DB to new server,

1.Install MS SQL on new host

2.Copy data files to new host and then make sure SQL server is up and running.

3.Change the Profiles in CI server related to new DB

Currently, our server is local installation. do we have any issues with that ? If yes how can we resolve ?

Thanks

your strategy looks fine, but I never attempted moving a DB server. so, test this out with a test server first.

Also, you might need to change a few things here and there in SAP after the change. look at post-processing steps from the homogeneous system copy guide to see if some of those steps apply to you.
